摘　　要：在直径效应研究的基础上,测量了不同直径钝感炸药的拟定态爆速和波形,进一步探讨了拟定态波阵面上法向爆速Dn与当地曲率κ的关系(Dn不仅依赖于κ,还依赖于波阵面变化率κ′,在κ一定时,κ′越大,Dn越小),使该关系适用于整个波阵面范围内。同时,将改进后的Dn(κ)关系代入LS模型计算,与实验结果符合得较好。The phase velocity and wave shape of insensitive high explosive with diverse diameter were measured. Through analyses of those data,the relation of Dn and κ is discussed. With the same curve, the greater of the ratio of curve,the faster the reduction of normal velocity is. So the Dn（κ） is used in whole wave shape. The calculated result used by LS method with the new relation is in agreement well with the experimental data.
