摘　　要：为降低平面波透镜输出波形差,依据压制平面波透镜的典型波形图,采用反算法推算出在透镜的分段区间内的实际爆速,根据费马原理分段设计透镜界面曲线,再对分段界面曲线进行调整处理,从而拟合出界面曲线的设计坐标。之后根据该设计加工透镜并进行爆轰波测试。结果表明:该设计方法使得透镜输出波形差大大降低,Φ100 mm及Φ60 mm透镜输出波形差均小于0.03μs。To decrease the wave time difference of pressed planar wave lens,the actual detonation velocity of each subsection of the wave lens was reversely calculated according to the wave plots,and the interfacial curve was designed dividedly based on Fermat′s principle.Then the coordinates of the interfacial curve were fitted out by adjusting the divided interfacial curves.The designed wave lens was manufactured and the blast wave was detected.Results show that our design method can decrease the wave time difference greatly.The wave time differences for Φ100 mm and Φ60 mm wave lens were both less than 0.03μs.
