摘要

本文用静态体视法测定了在饱和点为313.15K的水溶液中甲酸铵晶体不同晶面的生长速率与过饱和度之间关系的动力学数据.应用BCF面扩散模型计算了晶体生长四个步骤的活化能及有关参数.并用Gilmer、Ghez和Cabrera的耦合理论推算了甲酸铵生长过程的“阻抗”

从而探讨体扩散对甲酸铵单晶生长速率的影响.

Abstract

The growth rate data of HCOONH4 crystal faces as a function of supersat-uration at 313.15K were measured. Bennemas modification of BCF surface diffusion model was applied to crystal growth from solution

and the values of growth parameters were calculated. The influence of volume diffusion on the growth rate of HCOONH4 crystal was discussed in light of the coupling model Gilmer

Ghez

and Cabrera.
