摘　　要：钝感炸药爆轰波的传播与波阵面当地平均曲率密切相关,为研究这种爆轰波传播的非理想行为,本文通过光电联合测试方法测量了常温下Φ10mm、Φ12.5mm、Φ15mm和Φ30mm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与当地平均曲率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,当波阵面当地平均曲率κ较小时,法向爆速Dn只与κ有关,而当κ较大时,法向爆速Dn不仅与当地平均曲率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 rate sticks at the temperature 24℃ , with diameters of 10,12. 5 ,15 ,30 mm respectively. Wave shape data were fit with an analytic form,by which the normal velocity Dn (κ) was calculated. The data confirm that the local normal wave velocity Dn 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.
