分别以碳掺杂的乙醇、甘油、单推-3和聚叠氮缩水甘油醚（GAP）为典型的液态工质，在不同能量激光注入的情况下，研究了烧蚀产物及其诱发的工质溅射，获得了推力变化规律。结果表明，溅射初期的高速喷射过程是推力形成的主要阶段。随后的溅射过程使质量流量增大，但对冲量耦合的贡献较小，进而使得整体推进性能下降。

By taking glycerol, ethanol, DT-3 and glycidyl azide polymer (GAP) all with carbon doped as typical liquid working substances, and under different incident laser energies, the ablation product and the splash of working substance induced by this ablation product are investigated, and the thrust evolution law is obtained. The results indicate that, the high speed splash process at the beginning of splash is the main stage of thrust formation. The subsequent splash process makes the mass flow rate increase, but makes less contribution to impulse coupling, which inversely degrades the overall thrust performance.
