1987年,我国首次成功地利用返回式卫星进行了空间微重力下的材料加工实验。在这次实验中,我们利用卫星的多用途加工炉成功地进行了三个偏晶合金样品的重熔实验,获得了地面无法得到的有大比重差的均
In 1987, for the first time, China successfully used the return satellites to carry out material processing experiments under the spatial microgravity. In this experiment, we successfully carried out the remelting experiment of three samples of deviatoric alloy by satellite multi-purpose processing furnace and obtained the results
