空间材料科学研究的主要目的在于利用空间环境,制备地面无法得到的新材料和在空间实现材料新工艺.然而,空间实验机会十分难得,且耗资甚巨.为此,各国科学家在地面建造了各种模拟空间环境的实验设施.落管就是其中之一.它是垂直安置并抽成真空(或根据需要充以某种惰性气体)的长管.样品在其顶部的熔化室熔化后成液滴状自由下落,并在下落时产生的失重和无容器过程中凝固,以进行空间材料研究的模拟实验.
The main purpose of space material science research is to make use of space environment, to prepare new materials that are not available on the ground and to realize new material technology in space, however, the space experiment opportunities are very rare and costly, therefore, scientists from all over the world built One of them is a test tube that mimics a space environment, one of which is a long tube that is placed vertically and evacuated (or filled with some inert gas if required). The sample melts into a liquid droplet at the top of the chamber Free-falling and solidifying during weightlessness and vessel-free processes on fall, for simulation experiments in space material research.
