英文摘要：

The fields of public security, food security, environmental protection, industrial process monitoring and manned space and explorations need miniature mass spectrometers in emergency, which is used for on-line detection and analysis of composition. The vacuum degree requirement of ion trap mass spectrometer is lower than those of other mass spectrometer, and operating performance of ion trap mass spectrometer（MS） has advantages such as flexible and tandem MS, more suitable for miniaturization and micromation. Miniature ion trap mass spectrometer, development of MEMS ion trap mass spectrometer and its application in field of space are summarized, main technical bottlenecks of ion trap mass spectrometer in miniaturization is tried to find out and solutions are put forward. In the end, development of miniature ion trap and its application prospect in the field of space is discussed.
