微重力条件下晶体生长过程的实时观察

IN SITU OBSERVATION OF THE CRYSTAL GROWTH PROCESS UNDER MICROGRAVITY

从材料科学的微重力效应和晶体生长基本过程等两个方面出发，阐明了一种新的生长技术（晶体生长过程的光学实时观察法）的必要性，并介绍了空间高温实时观察装置的基本特性．在我国的科学技术探测卫星上，该装置进行了搭载实验，并首次清楚地观察到了空间溶质扩散效应和高温溶液的表面张力对流图像．

The necessity for a new crystal growth technique with in situ optical observation is illustrated from two aspects:microgravity effects and the crystal growth process. We describe the features of a high temperature in situ space observation instrument in which a flight experiment has been successfully conducted aboard a Chinese scientific experimental satellite. The diffusion of the high temperature solute and the surface tension convection of the high temperature solution in space have been clearly observed for the first time.
