在最一般的情况下，导出了Wertheim形式中任意混合带电硬球在粘点吸引下的平均球近似热力学。结果表明，静电过剩热力学仍然可以由依赖于屏蔽参数ΓB的相对简单的公式计算。我们还引入了一个新的指数近似，与我们以前的工作中讨论的更简单的平均类球近似不同，它具有正确的低密度行为。明确讨论了具有单一缔合常数的二元混合物的限制情况。
The thermodynamics of mean spherical approximation for an arbitrary mixture of charged hard spheres with sticky‐point attraction in the Wertheim formalism is derived for the most general case. It is shown that the electrostatic excess thermodynamics can be still computed from relatively simple formulas which depend on the screening parameter ΓB. We introduce also a new exponential approximation, which unlike the simpler mean spherical‐like approximation discussed in our previous work, has the correct low density behavior. The restricted case of a binary mixture with a single association constant is discussed explicitly.
