为研究微重力条件下胶体晶体生长动力学和结构变化的规律，设计了空间胶体晶体生长实验装置。实验装置同时搭载三个实验样品，每个实验样品有两个实验工位。通过对胶体晶体的实空间成像及倒易空间衍射（ Kossel 衍射）成像分别实现样品形貌及样品晶体结构的观测。在完成的空间搭载飞行任务中，获得的大量空间及地面实验数据，结果表明微重力环境中的胶体晶体样品有更好的稳定性。

To study the growth kinetics and structural transformation of colloidal crystals under mi-crogravity condition , an experimental device with three crystallization cells , each with two working positions was designed .It uses direct-space imaging with white light to monitor morphology of the crystals and reciprocal-space laser diffraction ( Kossel lines ) to reveal the lattice structure .The de-vice , intended for colloidal crystal growth on Tiangong-1 target spacecraft , had run on-orbit for more than one year till the end of the mission .Hundreds of images and diffraction patterns were collected via the on-ground data receiving station .The data showed that single crystalline samples were suc-cessfully grown on the orbit .Preliminary results indicated that the on-orbit crystals were more stable than those on the ground .
