讨论了研究复杂带电分子体系的一般变分方法。在这种方法中，自由能泛函的变分试验函数构造的渐近极限（AL）形式的直接相关函数。一些例子进行了讨论，并在每种情况下的变分形式的直接相关明确给出。详细讨论了与Onsager的将系统浸入无限导电流体中以获得能量界的过程的关系。
A general variational approach to study systems composed of complex charged molecules is discussed. In this approach the variational trial functions for the free energy functionals are constructed from the asymptotic limiting (AL) forms of the direct correlation functions. A number of examples are discussed, and in each case the variational form of the direct correlation is given explicitly. The relation to Onsager’s procedure of immersing the system in an infinite conducting fluid for obtaining an energy bound is discussed in detail.
