| 摘 要： | 采用密闭爆发器测试了80目、100目和120目三种粒径的RDX的燃烧输出压力时间曲线。结果表明，在一定装填密度下，RDX粒径越小，压力指数越大，压力输出时间越短。通过对RDX粉两相燃烧过程的分析，指出RDX粒径对压力变化率曲线有影响。

| Abstract: | The p~t curves of 100 meshes and 80 meshes RDX are measured with the closed bomb test. The results show that reducing the particle size may enhance the pressure exponent. Furthermore, the two phase combustion process of RDX is analyzed, it can be seen that the particle size has an effect on the dp/dt~t relations of combustion. |
