我国卫星搭载晶体试验成绩显著据中国空间技术研究院透露，我国通过卫星搭载进行砷化镓晶体太空试验，取得重大成果，已获得一批在太空生长的优质半导体。砷化镓晶体是微波通信、特别是卫星通信的急需材料。我国于１９８７年秋，通过卫星搭载试验，获得了世界上第一块空间... China’s satellite equipped with crystal test results significantly According to the China Academy of Space Technology revealed that China carried out by a satellite space-GaAs crystal test, and achieved significant results, has been to obtain a number of high-quality space in the growth of semiconductors. Gallium arsenide crystals are a much needed material for microwave communications, especially for satellite communications. My country in the autumn of 1987, through the satellite carrying test, obtained the world’s first space ...
