摘　　要：在分散体系的研究中,也经常遇到园柱体型胶粒,例如蛋白质分子,海泡石和凸凹棒石粘土颗粒,它们都能用带电的园柱体型采近似处理。这种类型的颗粒以往研究不多,其原因大约有二,一是处理这类颗粒时,数学上的困难很大;二是这类颗粒之间的相互作用,和它们之间的取向有关。Sparnaay首先用Derjaguin法得出园柱体型颗粒处于平行和垂直位置时,相互排斥能的近似表达式。Brenner和McQuarrie(BM)A new method developed the double layer interaction free energe for two spherical particles by us, is extended, to the case of two cylindershape colloidal particles having equal radii(b). When a parallel body of the cylinder moves around other parallel body of cylinder, each orientation of anisometrie cylinder was taken account in calculating the interaction, energy, it is the average repulsive energy.This paper reports Monte Carlo (MC) computation on the two cylindershape colloidal particles in all relative position, MC simulation agrees with our results for kb=0.5 and kb=3
