摘　　要：介绍了金属氢化物(MH)对混合推进剂性能的影响,MH对混合推进剂性能具有一定的改善作用,尤其是某些MH能够显著提高混合推进剂比冲。指出MH混合推进剂技术将是推进剂的一个重要研究和发展方向,强调使用MH有益于推进剂性能的提升,但MH分解释放的金属(M)和H2聚集在大气层中,导致大气层污染,应引起有关研究机构的重视。The influence of metal hydride （MH） on the performance of the hybrid propellant is introduced. The MH possesses certain improving action on the performance of the hybrid propellant, especially some MHs can significantly increase the specific impulse of the hybrid propellant. It is pointed out that the MH hybrid propellant technique will be an important research and development direction. It is emphasized that although use of MH is favorable to increasing the performance of the propellant, the metal （M） and H2 released from the MH decomposition can be accumulated in the atmosphere and cause the atmosphere pollution. Therefore the relevant research institutions should pay enough attention.
