摘　　要：以国际公认理论完美的维里(VIRIAL)状态方程为基础,建立了VLW炸药爆轰产物状态方程,简述了VLW炸药爆轰产物状态方程的形成背景,呈现了VLW方程的推导过程;应用VLW方程计算了军用高能炸药、民用工业炸药、凝聚相炸药、气相燃料空气炸药的爆轰性能参数,以及火箭推进燃烧性能参数,推导了爆轰产物的热力学函数(内能、熵、化学位等)。结果表明,应用VLW方程计算的参数结果准确合理;成功解决了高温下(T*>20)高级维里系数计算难题,准确表达了爆轰条件下的维里方程属性。Based on the internationally recognized perfect VIRIAL equation of state,the equation of state for detonation products of VLW explosives was established.The formation background of the equation of state for detonation products of VLW explosives was briefly described,and the derivation process of VLW equation was presented.The detonation performance parameters of military high explosives,civil industrial explosives,condensed phase explosives and gaseous fuel air explosives were calculated by using VLW equation.The thermodynamic functions of detonation products(internal energy,entropy,chemical potential,etc.)were derived.The results show that the parameters calculated by VLW equation are accurate and reasonable,and the calculation problem of advanced VIRIAL coefficient at high temperature(T*>20)is successfully solved,and the properties of VIRIAL equation under detonation condition are accurately expressed.
