实践十号将开展什么样的科学研究?《科学世界》就此采访了实践十号卫星工程项目首席科学家、中国科学院力学所胡文瑞院士。科学世界:实践十号主要的目标是什么?胡文瑞:目标就是在微重力环境里做长时间的实验。这样的实验在地面上做不了。我们地面上的微重力实验室,物体从高塔上以自由落体下落,能保持失重的时间只有几秒钟,而返回式卫星可以在微重力条件下做时间长达十几天的实验。科学世界:实践十号搭载的科学实验是如何筛选出来的?胡文瑞:筛选非常严格。很多研究,在地面上由于重力的
Practice on the 10th will be carried out what kind of scientific research? “Science World” interviewed this practice on the 10th satellite project chief scientist, Institute of Mechanics, Chinese Academy of Sciences Hu Wenrui academicians. Science World: What is the main goal of Practice No. 10? Hu Wenrui: The goal is to experiment with a long time in the micro-gravity environment. Such experiments can not be done on the ground. In our microgravity laboratory on the ground, objects fall free-fall from the tower and only allow a few seconds to remain in weightlessness, while return satellites can do experiments in microgravity for as long as a dozen days. Science World: Practice No. 10 carried scientific experiment is how to filter out? Hu Wenrui: screening is very strict. A lot of research, due to gravity on the ground
