摘　　要：钝感炸药爆轰波的传播与波阵面曲率密切相关 ,为研究这种非理想行为 ,通过光电联合测试方法测量了常温下直径为 10、12 .5、15、30mm的钝感药柱的定态爆速和波形 ,根据拟合的爆轰波形 ,分析了波阵面法向速度Dn与当地曲率κ之间的关系。结果表明 ,定态爆速随药柱直径的增大而增大 ,当κ较小时 ,Dn只与κ有关 ,当κ较大时 ,Dn不仅与κ有关 ,而且还与药柱直径有关。Steady-state detonation velocities and wave shapes were measured for JB-9014 (95 wt.% TATB+5 wt.% F2314) rate sticks at 24°C, with diameters of 10, 12.5, 15 and 30 mm respectively. Wave shape data were fitted with an analytical form, by which the normal velocity was calculated. The data confirm that the local normal wave speed depends only on the local total curvature κ for small κ, but it varies with both curvature and explosive diameter in the case of big κ.
