基于激光烧蚀液态工质的激光推进技术，由于工质的飞溅导致比冲较低．选择掺碳质量分数为0，0．1％，1％，5％的甘油为工质进行激光烧蚀，研究液体喷溅情况．实验结果表明：对甘油碳掺杂后，烧蚀产生飞溅现象明显减弱，因此可以推断其作为工质的比冲增大．通过对激波的演化分析发现含碳质量分数为1％的甘油激波速度最大，速度衰减也较慢，对激光的吸收效果较好．

Liquid ablation based laser propulsion has low specific impulse because of the splashing of work medium .In this paper ,the splashing phenomena were studied by ablating glycerol with 0 , 0 .1% ,1% ,5% mass proportions of carbon nanomaterial .Experimental results showed that carbon doping significantly weakened the splashing phenomena and thus increased the specific impulse .Shock wave analysis indicated that the shock wave speed of glycerol with 1% mass proportion of carbon was the fastest ,and the speed decay was slower ,the laser absorption effect was better .
