湖南省资兴市州门司镇中学黄巧强同学问:“搭载‘嫦娥’一号的‘长征三号甲’运载火箭的工作原理是怎样的?”侯要权同学问:“火箭升空靠气体的反冲作用而获得动力,当火箭进入大气层外的真空环境后是靠什么来提供动力?”我们现在试着来回答两位同学的问题.
Mr. Huang Qiaoqiang, a member of the state school in Jixing Township, Zixing City, Hunan Province, asked: “What is the working principle of the ’Long March 3A’ carrier rocket carrying the No. 1 ’?’ The air is backed by the recoil effect and gains momentum. When the rocket enters the vacuum environment outside the atmosphere, what motivates it?" We are now trying to answer the questions of the two classmates.
