我们延长我们早期的工作在多极和离子势的理论中使用Pade逼近。新的特点是（i）我们的工作扩展到混合多极项和极化率的包含，（ii）制定和实施一个系统的方法来获得理论中出现的所有两体和三体项的解析近似，（iii）评估离子Pade结果在离子溶液应用中重要的低浓度区域，（iv）在该低浓度区域中，在改进精确度的混合扰动理论中使用Pade。（iii）和（iv）的结果被用来研究最近由Stell，Wu和Larsen发现的显著的低密度带电球临界点。
We extend earlier work of ours on the use of Pade approximants in the theory of multipolar and ionic potentials. The new features are (i) extension of our work to mixed multipole terms and inclusion of polarizability, (ii) formulation and implementation of a systematic means of getting analytic approximations for all the two-body and three-body terms appearing in the theory, (iii) assessment of the ionic Pade results in the low-concentration region important in ionic-solution applications, (iv) use of the Pade in a mixed perturbation theory of improved accuracy in that low-concentration regime. The results of (iii) and (iv) are used to study the remarkable lowdensity charged-sphere critical point recently discovered by Stell, Wu, and Larsen.
