Design and Implementation of a Virtual Experimental Teaching System for Deep Energy Exploitation Based on Digital Twin Technology

The exploration and development of deep oil and gas resources are becoming the primary focus in the fossil energy sector, thereby increasing the demand for highly skilled engineers. Colleges and universities play a crucial role in cultivating talent in petroleum engineering. However, the current traditional teaching systems, particularly in experimental practices, face significant challenges, such as low efficiency, limited environments, and a disconnect between theoretical knowledge and practical application. To address these issues and enhance learners’ practical abilities and comprehension, we introduced digital twin technology into the experimental teaching of deep energy exploitation. This paper analyzes innovative pedagogical approaches, with a special emphasis on the real-time visualization of hydraulic fracturing. Supported by the National Key Laboratory of Chengdu University of Technology, our research team developed multiple digital twin platforms for both indoor and onsite hydraulic fracturing. These platforms utilize advanced algorithms and models, enabling real-time data acquisition and visualization analysis. Pilot teaching results demonstrate that the virtual experimental system based on digital twin technology encourages active learner engagement, improves their understanding of digitalization in engineering, and enhances their professional skills in deep oil and gas exploration. The digital twin-based visualization system is a valuable tool for experimental teaching in deep energy exploitation, and its application could serve as a model for other engineering disciplines.

Research on Teaching Reform of Chemistry Experimental Course under New Engineering Background

With the proposal of new engineering education concept, new challenges are posed to the teaching reform of chemical experiment course. This study aims to explore the teaching reform path of chemistry experiment course under the new engineering background, so as to improve the students' practical ability and innovation ability. As an important part of engineering education, the teaching objectives of chemistry experiment should be consistent with the new engineering education concept, and pay attention to cultivating students' ability to solve practical problems and teamwork spirit. At present, there are some problems in chemistry experiment teaching, such as outdated curriculum system, too theoretical experiment content, lack of combination with engineering practice, and low participation of students. These problems restrict the improvement of teaching quality, and can not meet the needs of new engineering education for talent training. Therefore, the primary task of the reform is to update the experimental curriculum system and integrate more experimental projects with engineering background and cutting-edge technology, in order to improve the practicality and challenge of the experiment. In terms of reform strategies, it is suggested to implement the "student-centered" teaching mode, and encourage students to take the initiative to explore and innovate through project-driven and problem-oriented teaching methods. At the same time, strengthen the integration of experimental teaching and theoretical teaching, so that students can deepen the understanding of theoretical knowledge in the experiment, and use theoretical knowledge to solve practical problems. In addition, the information level of experimental teaching should be improved, and virtual simulation and other technologies should be used to expand the space-time dimension of experimental teaching and improve the teaching effect. The change of the role of teachers is also the key. Teachers should change from the teacher of knowledge to the guide and collaborator of students' learning. By building an open and interactive classroom environment, stimulate students' interest in learning and innovative thinking. At the same time, the establishment of a diversified evaluation system, in addition to the investigation of students' experimental skills, but also should pay attention to the evaluation of their innovative thinking, teamwork and solving practical problems. To sum up, the teaching reform of chemistry experimental curriculum under the background of new engineering should focus on the update of curriculum content, the transformation of teaching mode, the integration of teaching resources and the reform of evaluation system. Through the implementation of these strategies, it aims to build an experimental teaching system that can not only meet the needs of new engineering education, but also cultivate high-quality chemical engineering talents. Such reform is of great significance to enhance the competitiveness of chemical engineering education in China.

Application of Virtual Simulation Technology in Chemical Engineering Practice Teaching Under the Background of New Engineering and Technical Disciplines

With the development of computer simulation technology, virtual experiment, as an effective supplement to traditional practice and experimental teaching, is one of the important means to strengthen practice teaching and improve teaching quality. Because the raw materials and processes of chemical and pharmaceutical enterprises, especially the dangerous typical chemical processes under key supervision, have high risks such as flammability and explosion, college students have no basic training opportunities for the operation of such processes. The virtual experiment teaching system, virtual simulation technology and man-machine interaction are adopted to conduct simulation experiments, which provide students with safer, more free and more flexible experimental scenes. The systems of operation interaction, task guidance and timely evaluation make up for many limitations of chemical engineering practice teaching. Students have a strong sense of experience. Digital and networked applications can help teachers organize online and face-to-face teaching, improve teaching evaluation and form a diversified teaching network. Under the background of new engineering and technical disciplines, the construction of virtual laboratory is a safe, economical and efficient chemical practice scheme, which can better meet the demand of the society for chemical talents in the information age.

Research on the experimental principle of deep integration of LETS software and criminal procedure under the background of artificial intelligence

Abstract The teaching of law courses in Legal Experimental Teaching System (LETS) enables students to have a clearer understanding of the litigation process, master the format and production of various criminal litigation legal documents and train their communication and collaboration skills in litigation by cooperating to complete the experimental process. However, there are some shortcomings in experimental teaching using the LETS system, such as teachers being unable give real-time guidance and unable to reflect the principle of direct speech in litigation. Given these problems, this paper proposes a framework for the deep integration of LETS software and criminal litigation under the background of artificial intelligence (AI). First, it introduces the current situation and development of criminal litigation under the background of AI. Then, a set of AI parameters is designed based on the background of LETS software and criminal proceedings deep integration framework, and at the same time, the framework is used for intelligent learning criminal proceedings. The experimental results show that LETS software can better match the algorithm of the AI environment to push personalised criminal procedure learning courses. The experiment also shows that this framework can provide new ideas and development for the future study of criminal procedure.
