摘　　要：作为衡量推进剂能量性能的主要指标之一,比冲有着重要的意义。更高的比冲意味着更快的航速和更远的航程。在现阶段的实验研究中,为了更好地利用该指标,开发出了瞬时燃速、平均瞬时燃速、瞬时比冲及平均瞬时比冲4个指标,利用这4个指标可以更好地表现出燃料的能量性能,同时可以验证通过实验得到的燃速公式,对推进剂能量性能和燃速公式的研究有着重要的意义。本文对瞬时燃速及平均瞬时燃速、瞬时比冲及平均瞬时比冲的概念与计算方法进行了详述,并进行了理论分析,并对瞬时比冲作了修正。修正后的瞬时比冲可以作为实测瞬时比冲参考,修正后的平均瞬时比冲与实测比冲的偏差在1%以内。As a main index of the measurement important meaning. Higher impulse means that it can of propellant＇s energy performance, impulse has very offer faster velocity and further sailing distance. In recent research, instantaneous burning rate, average instantaneous burning rate, instantaneous impulse and average instantaneous impulse are developed for further research. With these indexes, the performance of fuel can be represented better, and the burning rate formula can be tested. The research result can improve the research of the propellant energy performance and burning rate. In this article, the meaning and the calculating method of the four concepts are proposed and analyzed theoretically, and the instantaneous impulse is modified. The modified instantaneous impulse can be handled as the factual instantaneous impulse, and the deviation of the modified average instantaneous impulse and the factual impulse is always below 1%.
