采用Ｍａｃｈ－Ｚｅｈｎｄｅｒ干涉加载波技术，对于ＴＧＳ晶体生长固－液界面边界层进行了实时原位观察和分析．在实验条件下，观察到了界面边界层的厚度约为０．１５ｍｍ．对照１９８５年美国宇航局在空间实验室３号上完成的ＴＧＳ晶体生长观察结果，研究了重力对ＴＧＳ固－液界面边界层的影响．实验结果表明：（０１０）界面上的溶液浓度比（０１０）界面上的溶液浓度高２～３倍，（０１０）面边界层厚度比（０１０）面边界层高，边界层作为晶体生长的重要特征参量，明显受重力影响．
Using Mach-Zehnder interference plus carrier wave technology, the solid-liquid interface boundary layer of TGS crystal was observed and analyzed in real time. Under the experimental conditions, it is observed that the interface boundary layer thickness is about 0.15mm. In contrast to the results of TGS crystal growth measured by NASA in Space Laboratory No.3 in 1985, the effect of gravity on the boundary layer of the TGS solid-liquid interface was studied. The experimental results show that the solution concentration on the (010) interface is 2-3 times higher than that on the (010) interface, and the boundary layer thickness is higher on the (010) plane than on the (010) plane. Characteristic parameters, obviously affected by gravity.
