测定了铜锌系a相中扩散系数和迁移率随浓度的变化。使用增量扩散偶来确定不同浓度下的Kirkendall效应。Darken的分析被用来计算这些数据中的个体扩散系数和迁移率。一般扩散系数是该体系中浓度的单值函数，在所用实验方法的精度范围内。各种浓度函数(扩散系数和迁移率)的形式在每种情况下都是相同的：它基本上与通常的D-C曲线相同。
Diffusion coefficients and mobilities were determined as functions of concentration in the a phase of the Cu-Zn system. Use was made of incremental diffusion couples to determine the Kirkendall effect at various concentrations. Darken’s analysis was used to calculate the individual diffusion coefficients and mobilities from these data. The general diffusion coefficient is a single-valued function of the concentration in this system to within the limits of accuracy of the experimental methods used. The form of the various functions (diffusion coefficients and mobilities) of concentration is the same in every case: it is essentially the same as the usual D vs c curve.
