摘　　要：为研究石墨含量和粒度对RDX/石墨混合炸药爆速的影响,用电探针法进行了炸药爆速的实验研究,并与ω-Г余容公式的计算结果进行了比较。结果表明,余容公式未考虑石墨在爆轰波阵面上吸热对爆速的影响,使计算值比实验值高。改进ω-Г余容公式,考虑石墨含量和粒度对石墨吸热量的影响,使计算值与实验值的平均误差由1.68%减小到0.24%。To study the effect of graphite content and granularity on the detonation velocity of RDX/graphite mixed explosive,the experimental study of the detonation velocity was carried out with electric probe method,and the measured detonation velocity was compared with the calculated value from the ω-Г covolume formula.The results show that the calculated value from the ω-Г eovolume formula is higher than that from experiment because the heat-absorption of graphite on the detonation wave front is not taken into account in the formula.Improving the ω-Г covolume formula and considering the effect of graphite content and granularity on the heat-absorption of graphite make the average absolute error of the calculated detonation velocity with the experimental one decrease from 1.68％to 0.24％.
