Before launch, the secondary mirror support structure is folded or compressed, the telescope becomes short and compact. 在发射升空过程中,次镜支撑结构折叠或压缩,使得望远镜的长度减小,发射体积紧凑。
The analysis and computation show that folded waveguide circuit is available as slow wave structure for broadband high power TWT in short centimeter and millimeter wave range. 分析和计算表明,该电路很适合用作短厘米波和毫米波大功率行波管的慢波结构。
