초록
저온 고압하에 있는 He-CF4 및 He-CClF3 계내에서의 기체, 액체간의 평형상태가 실험 및 이론적으로 연구되었다. 기체상의 조성을 예측하기 위해 기상의 평형조성에 대한 완전한 열역학적 관계식을 획득하고 몇가지 이론적인 model을 시험했다. 그중 Lennard-Jones（6-12） classical potential function과 mixture energy parameter의 기하학적 mixing rule에 보정상수를 사용한 Kihara potential function에 기본을 둔 virial 상태방정식이 가장 만족할만한 결과를 보여 주었다.
The gas-liquid phase equilibria at low temperatures and high pressures have been studied both experimentally and theoretically for the helium-carbon tetrafluoride and helium-chlorotrifluoromethane systems. An exact thermo-dynamic expression for the gas phase equilibrium composition was obtained for the prediction of the gas phase composition.
Of the various theoretical models used for the evaluation of this expression, the virial equation of state based on the Lennard-Jones（6-12） classical potential function and the Kihara potential function with a correction to the geometric mixing rule for its mixture energy parameter gave quite satisfactory prediction of the gas phase compositions.
