Abstract	이 논문에서는 저자들이 앞서 발전시킨 다분자층물리흡착이론을 수정하여 새로운 흡착이론을 제안하였다. 이 새로운 이론을 여러가지 adsorbent-adsorbate 계에 적용시켜 본 결과 Type Ⅱ와 Type Ⅲ 흡착의 경우에는 이론치와 실험치가 잘 일치하였다. 뿐만 아니라 이미 발표한 이론으로써는 설명할 수 없었던 Type Ⅰ 흡착등온식도 새로운 이론으로는 설명할 수 있었다. 이 이론에 포함되어 있는 두 parameter q/q1과 a는 흡착열과 어떤 관계성이 있는 것으로 추측된다. In this paper a modified version of the theory of multilayer phsyical adsorption developed previously by the authors is presented. This new theory is applied to various adsorbent-adsorbate systems and excellent agreements between theoretical results and the observed data are obtained for Type Ⅱ and Type Ⅲ adsorption. In addition, the Type Ⅰ isotherm, which was not accounted for previously, can also be explained in terms of the newly derived isotherm. It is conjectured that two parameters involved in this theory, q/q1 and a, are somehow related to the heat of adsorption.
