介绍了靶线法测雷管破片速度及其分布的试验方法，给出了破片速度的衰减曲线以及破片速度沿雷管轴向的分有曲线．试验结果证明，该方法简便、可行．
This paper introduces the test method of the target line method for detecting the fragmenting speed and its distribution of the detonator, and presents the attenuation curve of fragment velocity and the curve of fragment velocity along the axial direction of the detonator. The test results show that the method is simple and feasible.
