效果砍平均，簇缩放的率(ACS ) 和在部分控告的特级的镍粒子的 uni 系统和双性人系统的簇尺寸分布(CSD ) 被 Brownian 动力学调查，并且在这些系统聚类性质与在非极的系统的那些相比。结果证明在双极的系统的 ACS 比在非极的系统的那些大。在单极的系统，聚类性质的行为不同：在更低的离子的集中(10%) ，斥力不是足够强壮的打破簇，但是可以极大地削弱他们。仅仅当单极的控告的粒子的集中足够大时，簇最后被击碎进更小的。在这个工作，离子的集中是 20% 。在交流之间的关系并且砍率在 0.1760.276 的一个代表范围跟随幂定律。这个范围在与试验性的数据的范围的一个好协议，但是它稍微向更低的限制被偏导。

英文摘要：

Effects of shear rates on average cluster sizes （ACSs） and cluster size distributions （CSDs） in uni-and bi-systems of partly charged superfine nickel particles were investigated by Brownian dynamics, and clustering properties in these systems were compared with those in non-polar systems. The results show that the ACSs in bi-polar systems are larger than those in the non-polar systems. In uni-polar systems the behavior of clustering property differs： at the lower ionic concentration （10%）, repulsive force is not strong enough to break clusters, but may greatly weaken them. The clusters are eventually cracked into smaller ones only when concentration of uni-polar charged particles is large enough. In this work, the ionic concentration is 20%. The relationship between ACS and shear rates follows power law in a exponent range of 0.176-0.276. This range is in a good agreement with the range of experimental data, but it is biased towards the lower limit slightly.
