中文摘要：

设计了一套溶液降温法晶体生长显微实时观察装置,对快速生长KDP晶体{101}和{100}表面形貌的演化过程进行了实时观测分析。测量了晶体表面生长层切向生长速度随溶液过饱和度的变化曲线,并利用台阶生长动力学方程计算了相关动力学参数。进行了Fe3＋掺杂实验,结果表明Fe3＋的存在会影响到不同晶面上生长层的动力学系数,从而改变KDP晶体表面生长层的切向生长速度。

英文摘要：

A set of device for in-situ observing crystal growth by temperature lowering method in solution was designed.The evolution of the {100} and {101} surface morphology of the rapid growing KDP crystal was in-situ observed and analyzed.The curves of growth layers tangential velocity on the solution supersaturation were measured.Kinetic parameters were computed by steps growth kinetics formula.The Fe3＋ doping experiments were carried out.It was found that Fe3＋ could change the kinetics coefficients of growth layers on different crystal faces,and consequently affects the tangential growth velocity of the growth layers.
