考察了多体效应（用Stutton－Chen势，SC．）对胶体聚团的影响并与双体（Lennard－Jones，LJ）势下的结果作了比较,研究表明，SC和LJ势下簇团的性质有其相似的一面，如，随着剪应力的增加，系统里颗粒的平均势能增加，而每个簇团的颗粒数减少；在较强的剪应力场里，簇团沿剪应力方向（X轴）被明显拉长且其主轴偏离X轴等.但它们间的差异也是明显的，在剪应力下SC系统内颗粒排列得更合理，从而使得平均位能比LJ系统低约1－3个对比能量单位，因而簇团较致密，分形维数较高；颗粒的平均位能，平均簇团大小和分形维数对剪应力的依赖均比LJ系统减弱．在某些条件下簇团的形貌特征也发生了一定程度的改变．
The effect of multi-body effect (Stutton-Chen potential, SC) on colloidal agglomeration was investigated and compared with that of the double body (Lennard-Jones, LJ). The results show that under SC and LJ potential, For example, with the increase of shear stress, the average potential energy of particles in the system increases, while the number of particles per cluster decreases; in the strong shear stress field, the cluster along the direction of shear stress (X-axis) is significantly elongated and the main axis deviates from the X-axis, etc. However, the difference between them is also obvious, and the particles in the SC system are arranged more rationally under shear stress, so that the average potential energy is about 1- 3 units of contrast energy. Therefore, the clusters are denser and the fractal dimension is higher. The dependence of average energy, average cluster size and fractal dimension on shear stress is weaker than that of LJ system. Under certain conditions, the morphological characteristics of the clusters also changed to some extent.
