摘　　要：为了测量全预制破片在爆轰驱动下的长距离飞行速度,采用梳状靶测量实验方法测量了全预制钨合金破片的飞行速度。介绍了梳状靶测量实验方法原理,给出了典型的梳状靶信号。梳状靶测量实验方法测量的全预制钨合金破片的飞行速度与光幕靶实验方法和理论分析的破片飞行规律进行比较,结果表明,梳状靶实验方法可行,并与高精度的光幕靶测量结果一致。Abstract ： In order to measure flying velocities of controlled tungsten alloy fragments under detonation driven, comb targets method was used to study the initial velocities. Schematic of comb targets and typical signal of comb targets were discussed. The experimental results of flying law and long distance flying time of tungsten alloy fragments were validated by laser measurement method and theoretical flying law of fragments. The results show that the comb targets method is feasible.
