摘要：

In 1897, Kohlrausch formulated an electrophoretic mathematics model. By using the model conjoined with divergence theorem, electroneutrality condition and some assumptions, for instance constant relative mobility and no diffusion and convection, He derived the so-called beharrliche function,viz.,Kohlrausch' regulating function1. The function shows that, for a steady-state boundary, the sums of the ionic concentrations divided by their mobilities on either side homogeneity solutions of a boundary are the same values and instead constant as a function of time and location. The regulating function is of university importance. It is found the function is of validity for moving boundary electrophoresis, isotachophoresis (ITP), zone electrophoresis(ZE) and isoelectric focusing (IEF),including capillary electrophoresis(CE).
