摘要
在微重力环境中,重力的作用几乎消失,液体的表面张力起主导作用,微重力下液体的流动特性和平衡界面也会产生显著变化.为了使学生们能更真切、更直观地观察到微重力下的奇妙现象,我们搭建了短时微重力系统并开展了一些实验演示与观测研究.通过微重力系统模拟微重力环境,可以清楚地观察到液体表面的变化,更有助于同学们深入了解微重力下的物理规律和实验现象,对于激发同学们认识和发现新的规律和总结新的定律具有重要意义.
Under microgravity condition, the force of gravity almost disappeared, and the liquid surface tension played a leading role. Both fluid characteristics and balancing interface also have significantly changed. In order to let students observe the wonderful phenomenon more closely and visually under microgravity condition, we have built a short-term microgravity experimental system and carried out some experiments and observational research. Through the microgravity environment simulated by the microgravity system, it could be more clearly to observe the change of liquid surface, which resulted in better comprehension of the students in physical laws and experimental phenomenon. It had significance to motivate the students to discover new physical laws and summarize new rules.
