本文导出了离子与库仑势和短程势相互作用的多组分溶液中溶质径向分布函数的精确形式积分方程。在某种意义上，这个方程类似于最近的流体理论的精确方程，但涉及平均力的德拜-休克尔势（即屏蔽库仑势加上短程势），而不是总的直接势。定义良好的近似产生类似于超网链和Percus-Yevick方程的方程。的离子溶液和离子晶体中的缺陷的方程的可能有用的指示。
An exact formal integral equation is derived for the solute radial distribution functions in a multi-component solution of ions interacting with a Coulomb potential plus a short-range potential. The equation resembles, in a certain sense defined by the use of a diagram formalism, the recent exact equation of the theory of fluids but involves the Debye-Hückel potential of average force (i.e. a shielded Coulomb potential plus the short-range potential) instead of the total direct potential. Well-defined approximations yield equations which are analogues of the hypernetted chain and Percus-Yevick equations. The possible usefulness of the equations for ionic solutions and defects in ionic crystals is indicated.
