| 摘 要： | 引用文献１有关ＴＡＴＢ炸药的状态方程、化学反应率函数、使用二维拉氏质团法程序，数值模拟了射流对ＴＡＴＢ和Ｘ０２（ＴＡＴＢ与ＨＭＸ混合）炸药的引爆特征。给出射流引爆裸ＴＡＴＢ和有２ｍｍ厚钢覆盖板情况的临界引爆判据。还揭示了ＴＡＴＢ和Ｘ０２两种炸药爆轰波传播的特征，前者为非理想传播，后者接近理想传播。

| Abstract: | Jet initiation process of TATB and X02 (mixture of TATB and HMX)explosives is simulated by means of the Lagrange 2D-FPM code,the equation of state of TATB and the chemical rate function being as listed in reference 1.The critical criteria of jet initiation both for the bare TATB and when covered with 2mm steel plate are obtained.The study also gives the propagation properties of the detonation wave for TATB and X02 explosives,where as the former has a nonideal propasation,the latter comes near to an ideal one. |
