Abstract
액체에 관한 hole theory를 사용하여 여러가지 액체들의 표면장력과 표면 각층의 excess molar sulface entropy 들을 계산하였다. 표면 첫째층의 것은 이상적인 분자가 표면을 형성할 때의 값 Rln2보다 다소 큰 값을 보여주며 액체 내부에 들어감에 따라 점점 줄어들어 저온에서는 셋째층부터 거의 없어진다. 그리고 알곤, 질소, 메탄, 벤젠 및 할로겐들의 표면장력을 계산하여 측정치와 비교하였다.

The excess molar surface entropies of each surface layers are calculated applying the modified significant structure theory of liquid. The calculated excess molar surface entropy for the first top surface layer is slightly greater than the entropy of surface formation of ideal molecules, the latter is equal to Rln2. The excess entropy for the second surface layer is small and that for the third layer is negligible at low temperatures. The surface tensions of argon, nitrogen, methane, benzene and halogens are calculated applying the modified significant structure theory of liquid.
