| 摘 要： | 采用高速运动分析系统研究了硝基甲烷爆轰产物在空气中的膨胀飞散过程，并利用热渗透理论计算了硝基甲烷爆炸热作用下铝粉颗粒温度响应。结果表明，硝基甲烷液体炸药爆轰产物膨胀初期阶段对铝粉颗粒的热作用明显优于其爆轰区阶段的热作用；而在许多研究中往往忽略了爆轰区对铝粉热作用的影响，小尺寸铝粉颗粒在炸药爆轰区也能够迅速被加热至活化温度而可能参与化学反应。

| Abstract: | A analysing system of high speed movement is used to record detonation products expansion process of Nitromethane(NM).The temperature response of aluminum particles is calculated by using thermal penetration theory under thermal effects of NM detonation. The results show that the thermal effect of NM detonation on aluminum particles is more intensive in expansion phase than that in region of NM detonation,whereas this effect on aluminum particles in detonation zone is neglected. Smaller aluminum particle in NM detonation region can be heated to its ignition temperature promptly,impling that aluminum oxidation reaction becomes possible in region of NM detonation. |
