九十七、我国卫星微生物材料实验成效显著 生物工程是当前高技术产业的热点之一,它将直接促进农业、医药和食品工业的发展。航天器上的微重力条件对各种微生物材料的培养和迅速增殖提供了理想的环境。因为要使各种微生物迅速、大量地增殖,需要均匀地供给养料和空气,地面上因密度差异,气体和液体有固定的分界面,流体中只溶入少量气体,妨碍了
97. Significant Achievements in Experiments of Satellite Microbial Materials in China Bioengineering is one of the hot spots in the current high-tech industry. It will directly promote the development of agriculture, medicine and food industries. The microgravity conditions on the spacecraft provide an ideal environment for the cultivation and rapid proliferation of various microbial materials. Because a variety of microorganisms are required to proliferate rapidly and in large quantities, nutrients and air need to be uniformly supplied. Due to differences in density on the ground and a fixed interface between the gas and the liquid, only a small amount of gas is dissolved in the fluid,
