摘　　要：采用Hybrid反应率结合修正的JWL方程,研究了LX-17、超细TATB等钝感炸药的冲击起爆(SDT)过程,并计算了爆轰波的对碰现象。结果表明,该方法计算钝感炸药的冲击起爆过程与实验数据符合较好;计算爆轰波对碰区的峰值压力提高了10%。The shocking-to-detonation transition （SDT） of insensitive high explosives （IHE） including LX-17 and ultrafine TATB was studied by using Hybrid reaction rate model and modified JWL equation of state （EOS）, and phenomena of colliding diverging detonation was numerically simulated. The calculated shocking-to-detonation transition （SDT） of insensitive high explosives is in agreement with the experimental result, and the calculated peak pressure in colliding diverging detonation increases 10%.
