摘要/Abstract

摘要： 采用自主研制的考虑产物组分间化学反应的类CHEQ程序研究HMX炸药爆轰产物物态方程，给出初始密度为1.90 g·cm^-3的HMX炸药CJ点的爆速和爆压，计算值与实验值符合较好；计算CJ点的爆轰产物组成，并与BKW和LJD的计算结果进行比较分析；同时给出过CJ点的等熵膨胀线上压强、 γ和产物组分随比体积的变化规律，加深对爆轰产物作功能力的认识.

Abstract: Equation of state of detonation products for HMX explosive is calculated. Detonation velocity and detonation pressure at CJ point are calculated as initial density of HMX explosive is 1.90 g·cm^-3. It shows satisfactory agreement with experimental data. Mole numbers of various detonation products are predicted and compared with results of BKW and LJD. Pressure, γ and mole numbers of detonation products along CJ adiabatic expansion path are given. They are helpful for understanding phenomenon of detonation.

Key words: detonation products, equation of state, HMX explosive
