Abstract
표면상에서의 흡착현상 중, 특정한 압력에서 흡착량이 불연속적으로 급격하게 증가하는 2상 공존현상을 이론적으로 설명하기 위하여 2차원 클러스트 응집모형을 도입하였다. 이 2차원 클러스트 응집모형에 기초적인 통계열역학과 미정계수법을 적용하여 흡착등온식을 유도하였으며, 유도된 흡착등온식은 표면흡착에서의 2상 공존현상이 흡착입자들 간의 강한 인력에 의한 것임을 정성적으로 잘 보여주었다. We have introduced two dimensional cluster aggregation model to explain theoretically two phase coexistence phenomena such that adsorption is increased sharply discontinuous in particular pressure on the surface. And then, we have derived adsorption isotherms by applying fundamental statistical thermodynamics and Lagrange multipliers to the our model. By analyzing the our derived adsorption isotherms, we can explain well qualitatively that two phase coexistence on the surface adsorption would be a phenomena that occurs with the strong attractive forces between the adsorbed particles.
