| Abstract | 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。 |
| Other Abstract | To study the growth kinetics and structural transformation of colloidal crystals under microgravity 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 device,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 successfully grown on the orbit. Preliminary results indicated that the on-orbit crystals were more stable than those on the ground. |
