使用原位干涉显微镜方法研究了铁和铝杂质对层生长速率与溶液过饱和度的依赖性的影响。确定了过饱和死区以及当速率随不同杂质浓度急剧增加时的临界过饱和值。对这些杂质塞子的减速作用的分析表明，它们被牢固地吸附在表面上，并且Cabrera-Vermilyea机制正在发挥作用，但塞子如何被晶体捕获的问题仍然没有答案。
The influence of iron and aluminium impurities on the dependence of the layer growth rate versus the solution supersaturation was studied using the method of in situ interference microscopy. The dead zone of supersaturations was determined as well as the critical supersaturation value when the rate sharply increases with different impurity concentrations. Analysis of decelerating action of these impurity stoppers shows that they are firmly adsorbed by the surface and the Cabrera-Vermilyea mechanism is at work, the question of how the stopper is trapped by the crystal is still unanswered.
