英文摘要：

This paper mainly introduces several common Mg based alloys and its kinetics of hydrogen absorption and desorp-tion behavior. The kinetic model and mechanism of hydrogen absorption and desorption are summarized. The differences and charac- teristics of the common kinetic models are compared and analyzed. Moreover, the existing problems and future development of Mg based hydrogen storage alloys in kinetic experiment and model research are analyzed , and the future development trend is also ana- lyzed and forecasted.
