用激光散斑照相研究DKDP晶体生长过程

Study of the Growth Process of DKDP Crystal Using Laser Speckle Photography

溶液晶体生长与溶液的过饱和度及浓度变化有关。用激光散斑照相测定 DKDP 晶体的浓度扩散层和晶面浓度,以观察浓度变化,研究反应历程和反应机制,并决定生长所采用的方法。

Crystal growth in solution is related to the supersaturation degree of the solutionand the concentration variation of the solution.In the paper presented here,the concentrationdiffusion layer and the concetration about crystal face of DKDP crystal are measured by laserspeckle photography so that the concentration variation can be observed.This is very importantfor both the study of reaction process and reaction mechanism and the determination of the ap-proach used during growth.
