讨论了液滴热毛细迁移的空间实验装置,该实验是中国神舟号飞船中的一个项目.与国际上同类装置比较,它具有不需要宇航员直接操作,依靠程序自动控制及遥科学手段完成全部科学实验的能力.它不仅能完成大Reynolds数的液滴迁移实验,而且在这类空间装置上使用了等厚型光学干涉系统. The space experiment device for the thermal migration of liquid droplets is discussed, which is a project of Shenzhou spacecraft in China.Compared with other similar devices in the world, it has the advantages of direct operation without astronauts, automatic control and telematics The ability to conduct scientific experiments not only enables large Reynolds number droplet migration experiments, but also uses isoptical optical interferometry systems for such space devices.
