在最近的出版物中，Horvath、Dyment和Mehrer（以下简称HDM）提出了-Zr的自扩散系数Dsub（m）随温度变化的测量结果。在单晶样品上进行的该研究的结果是异常的，因为log Dsub（m）与1/T（K）的曲线不仅是非线性的，而且随着1/T的增加显示出两个向下弯曲的区域。HDM表示，他们无法看到任何解释其异常的自扩散结果。这封信的目的是指出一种解释这些反常结果的方法，并建议进行一些实验来检验这一建议。（orig./ RK）。
In a very recent publication, Horvath, Dyment and Mehrer, henceforth HDM, presented measurements of the self-diffusion coefficient Dsub(m) for -Zr as a function of temperature. The results of that study, done on a single crystal sample, were anomalous in the sense that a plot of log Dsub(m) vs. 1/T(K ) was not only non-linear, but exhibited two regions of downward curvature with increasing 1/T. HDM indicated that they were unable to see any explanation of their anomalous self-diffusion results. It is the purpose of this letter to indicate a means whereby these anomalous results may be explained and to suggest some experiments which might be undertaken to test the proposal. (orig./RK).
