中文摘要：
为了确定爆轰波法向速度Dn与当地曲率κ的定量关系,用光电联合测试法研究质量配比分别为60/40、50/50及40/60时HMX/TNT炸药的Dn-κ关系。结果表明,爆轰波延滞距离z随TNT含量的增加而增大;爆轰波延滞距离z随着炸药密度ρ的增大而减小;随着TNT的含量增加,Dn-κ曲线的斜率逐渐增大,且斜率增大的速率为正值。为了减少实验标定费用,引入了新变量Rt,将Dn-κ关系推广为Dn（κ,Rt）关系,并给出相应Rt-z-r关系。
英文摘要：
Aimed at the fact that it is necessary to determine the quantitative relation between the local normal detonation wave speed Dn and the total curvature κ when detonation shock dynamics（DSD） is used to study nonideal detonation,steady-state detonation velocities and wave shapes were measured for HMX/TNT cast explosives at mass ratios 60/40,50/50 and 40/60.Results show that detonation lag z increases with the increase of TNT mass percentage and it decrease with the increase of explosive density;and that with the increase of TNT mass percentage,the slopes of Dn（κ） curves become large and the change rates of the slopes are positive.For reducing the costs of the experiment,the general Dn（κ,Rt） law was induced from the relation of Dn（κ）,and the relation of Rt-z-r was obtained by the Dn（κ,Rt） law.
