在简单液体的分布函数理论中引入了一个新的量--液体结构因子的等温压力导数。结果表明，三重态关联函数和某些其他量可以用这个实验量和通常的液体结构因子来表示。通过对Rb、四氯化碳和Ar中液体结构因子及其压力导数的实验测量，作者研究了三重关联函数，并在可能的情况下测量了它的范围。此外，还将Born-Green方程、超网链方程和Percus-Yevick方程写成结构因子与其压力导数之间的关系。
A new quantity, the isothermal pressure derivative of the liquid structure factor, is introduced into the distribution function theory of simple liquids. It is shown how the triplet correlation function and certain other quantities may be expressed in terms of this experimental quantity and the usual liquid structure factor. From experimental measurements of the liquid structure factor and its pressure derivative in rubidium, carbon tetrachloride and argon, the authors have studied the triplet correlation function and, where possible, measured its range. In addition the Born-Green, hypernetted chain and Percus-Yevick equations are written as relationships between the structure factor and its pressure derivative.
