摘要

推导出了多粒子悬浮液中球形胶体粒子在突然施加阶跃外电场时随时间变化的瞬态电泳迁移率的拉普拉斯变换的一般表达式。根据一般迁移率表达式，我们得到了弱电荷球形胶体粒子在电解质溶液中随时间变化的瞬态电泳迁移率的拉普拉斯变换的简单封闭式表达式。得到的粒子瞬态电泳迁移率的拉普拉斯变换不涉及数值积分，因此可以使用计算软件轻松得到其逆向拉普拉斯变换。图解摘要多粒子悬浮液中球形胶体粒子随时间变化的瞬态亨利函数。

Transient electrophoresis of spherical colloidal particles in a multi-particle suspension

A general expression is derived for the Laplace transform of the time dependent transient electrophoretic mobility of spherical colloidal particles in a multi-particle suspension when a step external electric field is suddenly applied to the colloidal suspension. From the general mobility expression, we obtain a simple closed form expression for the Laplace transform of the time-dependent transient electrophoretic mobility of weakly charged spherical colloidal particles in an electrolyte solution. The obtained Laplace transform of the transient electrophoretic mobility of particles does not involve numerical integrations so that its inverse Laplace transform is easily obtained using calculation software.

Graphical Abstract
