摘要: 研究了不同配比HMX/TNT炸药的Dn()关系,并与不同配比RDX/TNT 炸药的Dn()关系进 行了对比。结果表明,配比相同时HMX/TNT炸药Dn()关系曲线总是在RDX/TNT炸药Dn()关系曲线 上方;RDX/TNT和HMX/TNT炸药的Dn()关系曲线随着炸药中TNT含量增加而下移。引入变量Rt 分 别将两种混合炸药的Dn()关系推广为Dn(,Rt)关系,给定变量Rt 就可以通过Dn(,Rt)关系得出相应未标 定的Dn()关系,Dn(,Rt)关系不仅可以减少实验标定次数,并且能满足DSD方法计算精度要求。Abstract: Itisnecessarytodeterminethequantitativerelationbetweenthelocalnormaldetonation wavespeedDnandthetotalcurvaturewhendetonationshockdynamics(DSD)isusedtostudynonidealdetonation.
