| 摘 要： | 1引言在电化学过程中，电迁移作用的存在使得离子的传质问题复杂化，这是因为近电极处的电势梯度与溶液中的各种高于分布有关。Newman［‘，‘］等曾研究过电化学溶液中离子迁移效应对离子传质的影响，并采用数值计算方法讨论了静止溶液中几种不同电报过程中的传质状况。对流场参数测量电极而言，理论分析的目的是希望得到可测量（电流）与流场参数的函数关系，故数值计算法不大适用。作者［’，‘］提出的稀电解质溶液中传递现象电化学测试法，给出了一种得到近似理论解的方法。本文进一步给出了迁移作用存在下驻点区域的传质理论解并将其…

| Abstract: | Under the existence of ionic migration effect, the differential equation describing mass transfer to stagnant point and its solution are deduced. Then the mathematical relation between current of measuring probe and liquid velocity is obtained. All the results in this paper can be also applied to the case without ionic migration effect. The theoretical result is verified by the experiment in which the ionic migration effect is changed by different concentrations of supporting electrolyte. |
