材料是现代科技的“四大支柱”之一,其可加工性能和使用性能在很大程度上依赖于环境条件的变化。把材料放到具有“微重力、无容器、超高真空”特性的空间环境中去研究,一些长期困扰和制约材料科学发展的难题将被攻破,从而为新型结构与功能材料的开发开辟了广阔而诱人的前景。为此,欧美等国的航空航天局从80年代以来,投入了大量的人才和巨资,进行着材料领域最尖端的研究。
Materials are one of the “four pillars” of modern science and technology. Their machinability and serviceability depend greatly on changes in environmental conditions. Put materials into the space environment with the characteristics of “microgravity, container-free and ultrahigh vacuum”, some of the problems that long plague and constrain the development of materials science will be broken, thus opening up vast areas for the development of new structures and functional materials And attractive prospect. To this end, NASA from Europe and the United States and other countries have invested a large amount of talents and huge sums of money since the 1980s to carry out the most advanced research in the field of materials.
