我们描述了一个实用的方法来计算系统的胶体颗粒附近的硬壁的迁移率矩阵。该方法原则上可以进行到任意精度和粒子数。我们利用这种方法进行斯托克斯动力学计算机模拟的胶体悬浮液在无界和有界流体。我们研究有限的颗粒群沉降平行于附近的硬墙的影响下，一个统一的力量。新格式的收敛性，壁对胶体动力学的影响，以及粒子间势和壁粒子势的附加效应都进行了检查。
We describe a practical approach for computing the mobility matrix of a system of colloidal particles near a hard wall. The approach can be carried out in principle to arbitrary accuracy and number of particles. We make use of this approach to perform Stokesian dynamics computer simulations of colloidal suspensions in both unbounded and bounded fluids. We study finite clusters of particles sedimenting parallel to a nearby hard wall under the influence of a uniform force. The convergence properties of the new scheme, the effect of the wall on the colloidal dynamics, and the additional effect of interparticle and wall–particle potentials are all examined.
