Deformation characteristics of a ring-stiffened cylindrical shell induced by shock waves and coalesced bubbles in double-charge underwater explosions

This study investigates the deformation characteristics of a ring-stiffened cylindrical shell induced by shock waves and coalesced bubbles in double-charge underwater explosions. A numerical model for coupling underwater multi-point explosion loads with the cylindrical shell is established by the Arbitrary Lagrange Euler method, and underwater explosion experiments with double charges are also conducted. The numerical model's effectiveness is validated by comparing shock wave superposition characteristics, bubble coalescence processes, and bubble pulsation periods with the experimental results. Based on the numerical model, the influences of detonation intervals and layout angles of charge on shock wave superposition effects, temporal and spatial distribution characteristics of shock waves, and the evolution process of coalesced bubbles in underwater explosions with double charges are explored. Additionally, the deformation characteristics of cylindrical shells induced by shock waves and coalesced bubbles for double charges with different detonation intervals and layout angles of charge are analyzed. The results indicate that double charges can induce more substantial deformation on the cylindrical shell at a specific detonation interval than a single charge with equal total mass. During the shock wave phase, the cylindrical shell's deformation decreases nonlinearly with an increased layout angle. Conversely, during the bubble load phase, the deformation of the cylindrical shell shows an approximately linear decrease with an increase in layout angle. A critical angle exists, below which the impact of double charges on the cylindrical shell is more substantial when detonated with an interval than simultaneous detonation.

Perturbing masses: A study of centered co-circular central configurations in power-law n-body problems

This research investigates centered co-circular central configurations in the general power-law potential n-body problem. Firstly, there are no centered co-circular central configurations exist when precisely n−2 of the masses are equal; secondly, unless all masses are equal, no such configurations exist when masses can be divided into two sets of equal masses; thirdly, no such configurations exist when masses is a mix of equal masses and some heavier (lighter) ones, arranged such that the heavier (lighter) ones are non-adjacent.

Preparation and Mechanism Analysis of Stainless Steel AOD Slag Mixture Base Materials.

To promote resourceful utilization of argon oxygen decarburization (AOD) slag, this research developed a new three-ash stabilized recycled aggregate with AOD slag, cement, fly ash (FA), and recycled aggregate (RA) as raw materials. The AOD slag was adopted as an equal mass replacement for fly ash. The application of this aggregate in a road base layer was investigated in terms of its mechanical properties and mechanistic analysis. First, based on a cement: FA ratio of 1:4, 20 sets of mixed proportion schemes were designed for four kinds of cement dosage and AOD slag replacement rates (R/%). Through compaction tests and the 7-day unconfined compressive strength test, it was found that a 3% cement dosage met the engineering requirements. Then, the unconfined compressive strength test, indirect tensile strength test, compressive rebound modulus test, and expansion rate test were carried out at different age thresholds. The results showed that the mixture's strength, modulus, and expansion rate increased initially and then stabilized with age, while the strength and modulus initially increased and then decreased with increasing R. Secondly, based on X-ray diffraction (XRD) and scanning electron microscopy (SEM) used to analyze the mechanism, it was found that the strength, modulus, and expansion rate of the new material can be promoted by blending AOD slag, due to its ability to fully stimulate the hydration reaction and pozzolanic reaction of the binder. Finally, based on the strength and modulus results, R = 3% was identified as the optimal ratio, which provides a reference point for the effective application of AOD slag and RA in road base materials.

Effects of the turbocharged Miller cycle strategy on the performance improvement and emission characteristics of diesel engines

The turbocharged Miller cycle strategy is studied to improve the power density of diesel engines and reduce emissions. A thermodynamic model and a 1D simulation model of turbocharged diesel engine are established. Results show that the introduction of the Miller cycle reduces the thermal efficiency under naturally aspirated conditions because of the low effective compression ratio, whereas it increases the thermal efficiency under a turbocharged condition owing to the energy recovered by the turbocharger. Under restricted combustion pressure and fixed intake mass, the thermal efficiency first increases and then decreases with increasing Miller cycle ratio, and the peaks occur at approximately 30%–50%. The gain of isochoric combustion ratio overlaps the loss of effective compression ratio due to the Miller cycle on the lower side, whereas it reverses on the higher side. With maximum and equal intake mass, the maximum power initially increases and subsequently decreases with increasing Miller cycle ratio, reaching a peak at 40%. Under a fixed isochoric combustion ratio, the thermal efficiency first increases and then decreases with increasing intake mass, and the optimum intake mass corresponding to the highest thermal efficiency decreases with increasing Miller cycle ratio. The lower the restricted combustion pressure is, the higher the gain in power and thermal efficiency by the Miller cycle strategy. Based on the calculation of the 1D model validated using a practical engine, the power can be increased from 41.6 kW/L to 100 kW/L while the brake thermal efficiency can be increased from 34.98% into 38.55% by increasing the Miller cycle ratio from 19% to 30% and the combustion pressure from 17.7 MPa to 35 MPa. With the application of the supercharged Miller cycle, when the Miller cycle ratio is 30% and the power intensity is increased from 60 kW/L to 100 kW/L, NOx decreases by 32.4%, CO decreases by 28%, showing a tendency to decrease and then stabilize, and HC increases by 5.3%. When the power is 80 kW/L and the Miller cycle ratio is increased from 10% to 30%, NOx decreases by 8.6%, CO decreases by 2%, and HC increases by 0.04%.

Neutrino phenomenology in a model with generalized CP symmetry within type-I seesaw framework

We investigate the consequences of generalized CP (GCP) symmetry within the context of the two Higgs doublet model (2HDM), specifically focusing on the lepton sector. Utilizing the type-I seesaw framework, we study an intriguing connection between the Dirac Yukawa couplings originating from both Higgs fields, leading to a reduction in the number of independent Yukawa couplings and simplifying the scalar and Yukawa sectors when compared to the general 2HDM. The constraints coming from CP symmetry of class three (CP3) results in two right-handed neutrinos having equal masses and leads to a diagonal right-handed Majorana neutrino mass matrix. Notably, CP symmetry experiences a soft breaking due to the phase associated with the vacuum expectation value of the second Higgs doublet. The model aligns well with observed charged lepton masses and neutrino oscillation data, explaining both masses and mixing angles, and yields distinct predictions for normal and inverted neutrino mass hierarchies. It features a novel interplay between atmospheric mixing angle θ23 and neutrino mass hierarchy: The angle θ23 is below maximal for the normal hierarchy and above maximal for inverted hierarchy. Another interesting feature of the model is inherent CP violation for the inverted hierarchy. Published by the American Physical Society 2024

Adsorption of salicyl hydroxamic acid and octyl hydroxamic acid mixture on the cassiterite minerals

Salicylhydroxamic acid (SHA) and octyl hydroxamic acid (OHA) are two commonly used hydroxamic acid-based collectors in fine cassiterite flotation. While some reports suggest that a mixture of OHA and SHA yields superior results compared to their individual use, there is a lack of experimental exploration and theoretical analysis. In this study, the flotation performance and the associated adsorption mechanism of SHA, OHA and their mixture on fine cassiterite particles was systematically investigated. The results demonstrate a synergistic effect between SHA and OHA in enhancing fine cassiterite flotation, with the most significant enhancement occurring at a 1:1 mass ratio under the natural pH conditions. This finding is corroborated by contact angle and zeta potential tests. When both SHA and OHA are present, SHA likely attaches to the cassiterite surface via chemisorption in the form of a five-membered chelate ring, while OHA adheres through physical adsorption, primarily establishing hydrogen bonds with oxygen sites on the cassiterite surface or with SHA molecules. The adsorption ratio of SHA to OHA onto cassiterite surfaces is approximately 69%: 31% when an equal mass of SHA and OHA interact with cassiterite under the natural pH condition.

Advancing lithium neutron capture therapy: 6Li-loaded nanoparticles and laser-driven neutron sources

We report on 6Li neutron capture therapy (LiNCT) in anticipation of using carbon nanoparticles to deliver targeted, high linear energy transfer radiation to non-resectable tumors. Our investigations show that, compared with existing 10B neutron capture therapy (BNCT), 6Li offers similar dose potential for equal mass density (DLi∼DB when mLi=mB), for capture products that span 7 times more range and approximately three cell lengths. Consequently, 6Li-filled nanoparticles dispersed more than half-a-cell-length apart, better convey high doses and ultra-high dose-rates, as LiNCT generates substantially less γ-rays and becomes more targeted than BNCT. To this end, we propose a neutron production scheme involving laser-plasma driven protons incident on various 7Li targets, capable of producing >109 n/sr/pulse. For high repetition frequency, efficient neutron moderation, and ideal 6Li concentration, the modality offers greater precision than existing neutron capture therapy.

Analysis of albedo and disc effects in the generalized restricted four-body problem

This manuscript explores the Generalized Restricted Four-Body Problem within the context of radiation pressure, the albedo effect, oblateness, and a disc-like structure that orbits around the primary bodies. We have considered that one of the primaries is a bigger primary, and the rest of the two smaller primaries are of equal masses, in which one of the smaller primaries is considered as a black body. Moreover, the perturbing forces by the effect of radiation pressure and oblateness are considered in the bigger primary. The effect of albedo and oblateness due to the second smaller primary is also taken into count. This study yields nine equilibrium points corresponding to various parameter values, including three collinear and six non-collinear equilibria. We conduct an analysis of the equilibrium points, their linear stability, and the motion around them. In the context of the considered parameter set, certain collinear equilibrium points exhibit stability, while others are unstable. Additionally, most of the non-collinear equilibrium points display linear stability. We also investigate variations in Jacobi’s constant and the positions of existing equilibrium points caused by the albedo and disc effects. It is found that the value of Jacobi constant CLj decreases with an increase in the mass parameter μ at the collinear points, which results in an expansion in the prohibited region. The inhibited zone of motion of the infinitesimal body is shown for different sets of parameters.

Orbital evolution of close binary systems: comparing viscous and wind-driven circumbinary disc models

ABSTRACT Previous work has shown that interactions between a central binary system and a circumbinary disc (CBD) can lead to the binary orbit either shrinking or expanding, depending on the properties of the disc. In this work, we perform two-dimensional hydrodynamical simulations of CBDs surrounding equal mass binary systems that are on fixed circular orbits, using the athena++ code in Cartesian coordinates. Previous studies have focused on discs where viscosity drives angular momentum transport. The aim of this work is to examine how the evolution of a binary system changes when angular momentum is extracted from the disc by a magnetized wind. In this proof-of-concept study, we mimic the effects of a magnetic field by applying an external torque that results in a prescribed radial mass flux through the disc. For three different values of the radial mass flux, we compare how the binary system evolves when the disc is either viscous or wind driven. In all cases considered, our simulations predict that the binary orbit should shrink faster by a factor of a few when surrounded by a wind-driven CBD compared to a corresponding viscous CBD. In-spiral time-scales of ∼106–107 yr are obtained for circular binaries surrounded by CBDs with masses typical of protoplanetary discs, indicating that significant orbital shrinkage can occur through binary–disc interactions during Class I/II pre-main-sequence phases.

Fermion Proca Stars: Vector-Dark-Matter-Admixed Neutron Stars

Dark matter could accumulate around neutron stars in sufficient amounts to affect their global properties. In this work, we study the effect of a specific model for dark matter—a massive and self-interacting vector (spin-1) field—on neutron stars. We describe the combined systems of neutron stars and vector dark matter using Einstein–Proca theory coupled to a nuclear matter term and find scaling relations between the field and metric components in the equations of motion. We construct equilibrium solutions of the combined systems, compute their masses and radii, and also analyze their stability and higher modes. The combined systems admit dark matter (DM) core and cloud solutions. Core solutions compactify the neutron star component and tend to decrease the total mass of the combined system. Cloud solutions have the inverse effect. Electromagnetic observations of certain cloud-like configurations would appear to violate the Buchdahl limit. This could make Buchdahl-limit-violating objects smoking gun signals for dark matter in neutron stars. The self-interaction strength is found to significantly affect both mass and radius. We also compare fermion Proca stars to objects where the dark matter is modeled using a complex scalar field. We find that fermion Proca stars tend to be more massive and geometrically larger than their scalar field counterparts for equal boson masses and self-interaction strengths. Both systems can produce degenerate masses and radii for different amounts of DM and DM particle masses.

Analysis of environmental performance indicators for concrete block manufacturing: embodied energy, CO2 emissions, and water consumption.

Concrete block production significantly contributes to environmental degradation. A thorough understanding of its ecological implications is critical for sustainable development. This study investigates concrete block manufacturing's environmental impact by quantifying embodied energy, CO2 emissions, and water consumption via a comprehensive life cycle assessment. An extended life cycle assessment methodology is utilized to quantify the environmental indicators throughout the concrete block production lifecycle. Primary industry data and secondary research data ensure accuracy and reliability. Findings showed that concrete block manufacturing requires 2.5-4.1 times more embodied energy than equal clinker mass. Cement and aggregate production and transportation account for substantial energy needs. Limestone calcination during cement production causes significant CO2 emissions, 2.3-3.3 times higher than the minimum. Water consumption is concerning during curing and washing. Exploring alternative cementitious materials, optimized processes, and water recycling can reduce embodied energy by up to 75%, CO2 emissions by up to 67%, and water consumption by up to 80%. Concrete block manufacturing necessitates considerable energy and generates significant emissions. Implementing sustainable measures can minimize embodied energy, CO2 emissions, and water consumption, enabling environmentally responsible manufacturing. This research emphasizes adopting sustainability practices to mitigate environmental impact. Policymakers, industry professionals, and researchers can employ these insights to develop effective strategies promoting green manufacturing. The concrete block industry can contribute to a sustainable future through sustainable practices.

Tailoring mechanical fatigue behaviour of LPBF-produced metal lattice structures while maintaining high manufacturability

Laser Powder Bed Fusion (LPBF) is increasingly being used for producing metal lattice structures (MLS) which offer a large freedom in tailoring strength, stiffness, and fatigue life whilst reducing mass. This can be done not only by altering the parent material but especially by adapting the geometrical characteristics of the unit cells. Unfortunately, not all unit cells can be accurately produced by LPBF. This paper presents a new strategy for connecting the well-known diamond unit cells in different manners, and with a focus on the mechanical performance of resulting samples under cyclic loading. It is shown that by changing the angle between two connected diamond unit cells by 90°, the resulting mechanical behaviour can be significantly altered without affecting manufacturability. Initial results presented in this work indicate that stiffness and fatigue life can be significantly improved compared to conventional diamond based lattices without affecting manufacturability and for equal sample mass.

Formulation Development of Directly Compressible Tablets Incorporating Trisamo Extract With Synergistic Antioxidant Activity.

This work investigates the synergistic antioxidant activity of the compositions of Trisamo (TSM) herbal formula containing the dried fruits of Terminalia chebula, Terminalia arjuna, and Terminalia bellirica. An augmented simplex lattice design was utilized to investigate the synergistic antioxidant activity, finding an equal mass ratio among the three herbal drugs to exhibit optimal synergistic antioxidant activity, with a combination index of less than 0.8. The optimal TSM extract was used to prepare directly compressible tablets employing a Box-Behnken design response surface methodology, optimizing compressional force (500, 1000, and 1500 psi), sodium starch glycolate (0%, 2%, and 4%), and magnesium stearate (0.5%, 1.0%, and 1.5%). Optimal parameters were a compressional force of 1000 psi, 2% sodium starch glycolate, and 0.5% magnesium stearate. The TSM extract tablet had a weight of 600.06 mg, a diameter of 12.78 mm, a thickness of 4.12 mm, a hardness of 6.85 kP, a friability of 0.30%, and a disintegration time of 1.81 min. Computer model predictions were verified with a low percentage error (≤ 10.00%). After 6 h, phenolic compounds were dissolved to an extent of approximately 40%-80%, including gallic acid (57.11%), corilagin (38.64%), chebulagic acid (58.49%), and chebulinic acid (81.44%). Stability data revealed that the phenolic compounds were retained for 3 months compared to the initial time point, with gallic acid at 81.43% and 100.27%, corilagin at 94.81% and 87.85%, chebulagic acid at 92.22% and 69.83%, and chebulinic acid at 107.00% and 85.54% at 30°C/75% RH and 45°C/75% RH, respectively. The summation of these four compounds did not change significantly when stored under either set of conditions. In summary, mixture design and response surface design were successfully utilized in the optimization of TSM extract tablets with synergistic antioxidant activity.

Combination of aloe emodin, emodin, and rhein from Aloe with EDTA sensitizes the resistant Acinetobacter baumannii to polymyxins.

The continuous emergence and spread of polymyxin-resistant Acinetobacter baumannii pose a significant global health challenge, necessitating the development of novel therapeutic strategies. Aloe, with its long-standing history of medicinal use, has recently been the subject of substantial research for its efficacy against pathogenic infections. This study investigates the potential application of anthraquinone components in aloe against polymyxin-resistant A. baumannii by liquid chromatography-mass spectrometry, in vitro activity assessment, and construction of animal infection models. The findings demonstrate that aloe emodin, emodin, rhein, and their mixtures in equal mass ratios (EAR) exhibit strain-specific antibacterial activities against polymyxin-resistant A. baumannii. Co-administration of EAR with EDTA synergistically and universally enhanced the antibacterial activity and bactericidal efficacy of polymyxins against polymyxin-resistant A. baumannii, while also reducing the frequency of polymyxin-resistant mutations in polymyxinssensitive A. baumannii. Following toxicity assessment on human hepatic and renal cell lines, the combination therapy was applied to skin wounds in mice infected with polymyxin-resistant A. baumannii. Compared to monotherapy, the combination therapy significantly accelerated wound healing and reduced bacterial burden. The combination of EAR and EDTA with polymyxins offers a novel therapeutic approach for managing skin infections caused by polymyxinresistant A. baumannii.

Preparation and mechanical characterization of multi-functional high-ductility engineered magnesium oxysulfate cement-based composites

Aiming at the integrated requirements of building energy saving and thermal insulation reinforcement in reinforcement engineering, the technology of preparing multi-functional high-ductility engineered magnesium oxysulfate cement-based composites (MOSC-ECC) by magnesium oxysulfate cement (MOSC) was proposed; the mechanism of industrial waste fly ash (FA) to improve the ductility of MOSC-ECC was explored; the effects of FA on the density, thermal conductivity and water resistance of MOSC-ECC were studied; the phase composition and microstructure of the hydration products of MOSC-ECC were analyzed. The results show that the incorporation of FA instead of light-burned magnesium oxide (LB-MgO) powder of equal mass can effectively reduce the cracking strength, fracture toughness, density and thermal conductivity of the matrix, and improve the ductility and multiple cracking ability of MOSC-ECC. The incorporation of hydrophobic agent made MOSC-ECC have excellent water resistance. The findings of this study provide useful knowledge for realizing the integrated design of thermal insulation and reinforcement of structures, which is of great significance for promoting the engineering application of ECC and the promotion of energy-saving green building materials.

Fabrication of Self-Standing Porous Foam-like PdM (M = Ni, Fe, Co) Nanocrystals for Boosted Ethanol Oxidation Electrocatalysis

Rational designing of self-standing porous foam-like PdM (M = Ni, Fe and Co) nanocrystals was achieved by a fast aqueous-solution method via the co-reduction of metal precursors using sodium borohydride. This was based on the crystallites’ coalescence growth mechanism, including quick nucleation of Pd that served as starting seeds for the nucleation of M, which attached directly along the specific crystallographic and lowered its high surface energy by diffusion of PdM atoms across the interface via Brownian motion to afford self-standing porous foam-like PdM nanocrystals. Amongst the as-prepared PdM nanocrystals, PdNi nanocrystals showed a superior alkaline ethanol oxidation reaction (EOR) activity and stability compared to PdFe, PdCo, Pd nanospheres (Pd-NSs) and commercial Pd/C (10 wt.%) catalysts. The EOR mass activity of PdNi was 1.32, 1.51, 2.01 and 24.05 times than those of PdFe, PdCo, Pd-NSs and Pd/C, respectively based on equal Pd mass. This was attributed to the lower synergistic effect in PdNi, which enhanced H2O activation/dissociation to give OH- species needed for rapid EOR kinetics, meanwhile, the porous foam-like morphology improved electron mobility and increased accessible active sites. This study revealed that low synergism in porous PdM nanocrystals is beneficial for enhancing the EOR activity and durability, which may allow the design of other binary Pd-based alloys for various electrocatalytic reactions.

Hydroisomerization of n‐dodecane over ZSM‐48 with different metal properties

AbstractThe distance between the two active sites of a bifunctional catalyst (acid sites and metal sites) is critical for the hydroisomerization performance. However, the influences of the dehydrogenation/hydrogenation species (Pt or Ni) and the intimacy between the acid sites and the metal sites over the distribution of the isomers have rarely been investigated. Herein, the bifunctional catalysts were prepared by loading the hydrogenation component (Pt or Ni) on γ‐Al2O3 or HZSM‐48 zeolite separately and then mixing them with equal mass of HZSM‐48 molecular sieves and γ‐Al2O3, respectively. The hydroisomerization performance of n‐dodecane was investigated on a fixed‐bed reactor. The loading position of the metal can directly affect the activity of the hydroisomerization reaction. However, the distribution of the isomer products is not affected by the loading position and the metal type (Pt or Ni) obviously, and the middle‐positioned isomer is the main isomer product regardless of the position and the type of the metal. The catalysis results indicate that the isomerization of n‐dodecane mainly follows the “Key‐Lock” catalysis mode on HZSM‐48.

Light curves from symmetric, polytropic contact binaries

ABSTRACT We study the structure of contact binaries assuming a polytropic relation between pressure and density, restricting ourselves to the case of equal-mass components, i.e. symmetric contact binaries. In this case, matter is at rest in the corotating reference frame making this problem far simpler than the general case of non-symmetric contact binaries. We compute these structures assuming values of the polytropic index of n = 0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, and 3.5 employing a self-consistent technique due to Hachisu. As a part of the results, we find the shape of their surfaces. While for the case of n = 3.5, such surfaces are very close to those corresponding to equipotentials of the restricted Lagrangian three-body problem, for lower n values the departure is remarkable. We propose a generalized function to fit these surfaces, which allows us to perform an accurate integration of the light curve due to the object. Then, for values of n > 0.0 we computed a family of light curves considering different inclinations and values for the width of the neck connecting the components (or equivalently, the fillout factor) of the pair. We compare our calculations with the solution found for the symmetric contact binary V803 Aquilae by employing the popular phoebe code, that assumes the above-mentioned Lagrangian equipotential surfaces. We conclude that considering polytropic structures leads to parameters that may be appreciably different from those deduced by assuming that their surfaces correspond to equipotentials of the restricted three-body problem.

Effects of onset of phase transition on binary neutron star mergers

ABSTRACT Quantum Chromodynamics predicts phase transition from hadronic matter to quark matter at high density, which is highly probable in astrophysical systems like binary neutron star mergers. To explore the critical density where such phase transition can occur, we performed numerical relativity simulations of binary neutron star mergers with various masses (equal and unequal binaries). We aim to understand the effect of the onset of phase transition on the merger dynamics and gravitational wave spectra. We generated a set of equations of states by agnostically changing the onset of phase transition, having the hadronic matter part and quark matter part fixed. This particular arrangement of the equation of states explores the scenario of mergers where mixed phases of matter are achieved before or during the merger. Under these circumstances, if the matter properties with hadronic and quark degrees differ significantly, it is reflected in the stability of the final merger product for the intermediate mass binary. We performed a case study on mixed species merger, where one of the binary companions is hybrid star. If quark matter appears at low densities, we observe significant change in post-merger gravitational wave analysis in terms of higher peak frequencies and post-merger frequencies in power spectral density. We report indications expressed as spikes in phase difference plots at merger time for mixed mergers. We found that the expression of phase transition in post-merger gravitational wave signals is more significant for unequal mass binary than for equal mass binary having the same total baryonic mass.

Determination of organic and inorganic Cl in gaseous ethylene based on gas-liquid equal mass response followed by automatic quick furnace-ion chromatography

Herein, a practical method for the determination of organic and inorganic Cl in gaseous ethylene by liquid standard samples was established; and then, the effects of various speciation and matrices on results were investigated followed by automatic quick furnace-ion chromatography (AQF-IC) analysis. From the evaluation of speciation and matrices, unified equation was explored and the method for accurately determining trace HCl with strong adsorption was also developed. First, summarize regularity that the light oil liquid standards themselves conformed to equal Cl mass response by AQF-IC (R2=0.99993). Then, the actual Cl mass in standard gas at 4 levels with different speciation and matrices were calculated by the same regularity based on the assumption of not affected by speciation or matrix change. The gas mass was accurately calculated based on Van der Waals’ Equation. As a result, combined with the theoretical Cl mass calculated by equation, the recoveries of the organic and inorganic Cl were in the range of 93.0%-101.4% [2.0 µmol/mol of CH3Cl/(N2+ethylene)], 93.4%-104.9% (10.1 µmol/mol of CH3Cl/N2), 101.6%-111.2% (20.2 µmol/mol of CH3Cl/ethylene) and 95.3%-101.0% (11.0 mg/m3 of HCl/N2), respectively, indicating the successful verification of above assumption rather than applying more exploration to rebuild relationships between different systems. As proof of principle and for more verification, system of CH2Cl2/He gas standard sample was prepared to explore the quantitative accuracy in more speciation with recoveries in the range of 91.3%-98.5%. In addition, the detection limit of Cl content based on S/N = 3 for ethylene was 0.06 mg/kg. Intra-day and inter-day relative standard devations (RSDs) were in the range of 9.3%-12.0% (≤1.0 mg/kg) and 2.5%-4.4% (>1.0 mg/kg). Finally, the developed method based on gas-liquid equal mass response was successfully applied in the actual samples of light olefins such as ethylene and propylene.
