摘　　要：本文介绍了微波电热推力器 ( Microwave Electrothermal Thruster—— MET)工作原理和地面实验系统组成 ,叙述了地面实验系统的启动与稳定工作过程、冷调试验、热试结果以及对热试现象和结果进行的分析 。The advantages and prospective applications of the Microwave Electrothermal Thruster (MET) are introduced in this paper.Then the working principle of MET and the configuration of the MET Ground Experimental System are discussed.The MET can produce stable resonance at the frequency of 2.45GHz.The startup and steady working processes of the Ground Experimental System are emphatically described.There are two sets of systems.The first system is low incident power (100W) and the other system is high (1000W).They can repeatedly startup and steadily work.The plasma can be observed through viewing window or quartz tube.The cold flow test phenomena and firing test results are analyzed.In the end,the proposal for future work is put forward.
