近年来,以航天为背景的命题时有出现,这类试题以社会热点问题为载体,富有时代感,符合“高起点、低落点”的命题思想,能够将与化学相关的实际问题分解,缩短了学科内容与高科技的距离。针对这一社会热点问题,本文精选一批与载人航天宇宙飞船(或运载火箭)材料、能源(燃料)、气体循 In recent years, propositions based on aerospace have appeared from time to time. These questions are based on social hot issues and are full of the sense of the times. They are consistent with the proposition of “high starting point and low falling point.” They can decompose and reduce the actual problems related to chemistry. The distance between subject content and high technology. In response to this social hotspot issue, this paper selects a batch of materials, energy (fuel), and gas circulation for manned space vehicles (or launch vehicles).
