晶体生长的台阶列运动的一个基本特点

An Character of the Movement of the Step Strains in Crystal Growth

本文介绍了用实时观察方法研究水溶液中晶体生长长机制的实验。通过对水溶液中ＣｄＩ＿２晶体的生长台阶运动的实时观察研究，首次提出了在过饱和度较小的条件下，生长台阶列的间距和生长界面上环境相的过饱和度成反比的结论。本文还给出了在一定的限制条件下，台阶列运动的这一特点的理论推导。

The experiment for study on the mechanism of crystal growth by in situ observation of CdI_2 crystal grown from the aqueous solution is reported in this paper. From the results of the experiment,we are concluded first time that at the low superaturation the distance between successive steps in the spiral is inversely proportional to the supersaturation of mother phase on the interface of crystal growth. This result can also be verified by theoretical analysis.
