VVT Ventui Vacuum Transducer

The study status of technology of space vacuum measurement is discribed briefly,and the two space vacuum gauges,that is the directional gauge with transducer and the directional gauge with stream detector is introduced in detail.

针对国内外在空间真空测量方面的研究状况作了简要描述,对研制的2种空间真空规(转换器方向性真空规和束检测器方向性真空规)进行了介绍,并对空间真空测量技术的后续研究工作作了展望。
