考虑了两种计算相互作用布朗粒子自扩散系数的方法。第一种方法是基于从Smoluchowski方程开始的布朗粒子的均方位移的计算。在第二种方法中，自扩散系数作为热力学驱动力和迁移率的乘积获得。讨论了这两种方法的优点和局限性。
We consider two ways to calculate the self-diffusion coefficient of interacting Brownian particles. The first approach is based on the calculation of the mean square displacement of a Brownian particle starting from the Smoluchowski equation. In the second approach the self-diffusion coefficient is obtained as the product of the thermodynamic driving force and the mobility. The advantages and limitations of the two methods are discussed.
