中文摘要：

以便与它的微观结构在轻媒介并且到一个系统的连接宏性质学习重粒子的不同类型的分发性质，在单极、双极的系统在的部分控告的金属性的粒子的径向分布函数(RDF ) 各种各样砍率被 Brownian 动力学调查模拟。结果与在非极的系统和另外的工作的相比在协议品质上或份量上好。调查显示在高离子的集中的单极的系统的粒子的可分散性最大。因此，为降水长成簇是大多数 unfavored。在双极的系统的可分散性是不到那在单极的系统，但是比那大在非极的系统。而且，在一样的所有 RDF 砍在三个系统的率接近限制，它暗示阀值价值存在。

英文摘要：

In order to study distribution properties of different types of heavy particles in light media and to link macro-properties of a system with its micro-structures, radial distribution functions（RDF） of partly charged metallic particles in uni- and bi-polar systems at various shear rates were investigated by Brownian dynamics simulation. The results are good in agreement qualitatively or quantitatively compared with ones in non-polar systems and other works. The investigation indicates that dispersibility of the particles in the uni-polar system of high ionic concentrations is the largest. Therefore, it is the most unfavored to grow into clusters for precipitation. The dispersibility in the bi-polar systems is less than that in uni-polar systems, but larger than that in non-polar systems. Furthermore, all the RDFs at the same shear rates in three systems approach a limit, which implies that a threshold value exists.
