菲克第二定律，作为菲克定律的进一步发展，它揭示了非稳态扩散过程中的重要关系。在距离x处，该定律表明，扩散物质浓度随时间的变化率，等于扩散通量随距离改变的负梯度。具体来说，我们可以用数学表达式来描述：(2) 式中，扩散通量与浓度和距离的关系可以写作：\[ \frac{\partial C}{\partial t} = ...
aFick’s second law. The time rate of change of concentration is proportional to the second derivative of concentration. This relationship is employed in nonsteady-state diffusion situations. Fick的第二法律。 集中的变动的时间率与集中第二种衍生物是比例。 这个关系在nonsteady状态扩散情况被使用。 [...
