模拟导爆管与雷管的装配 ,用动态数据测试分析系统测定了导爆管点火压力和点火冲量随传火孔直径的变化规律。对于 BSI型变色导爆管而言 ,当传火孔直径在 0 .6～ 1 .4mm范围内变化时 ,随着传火孔直径的增大 ,点火峰压和点火冲量均单调增大 ;而传火孔直径在 0 .2～ 0 .6mm范围内变化时 ,两者基本维持不变 The assembly of the detonating tube and the detonator was simulated. The dynamic data testing system was used to determine the variation of the detonating tube ignition pressure and ignition impulse with the passing fire hole diameter. For the BSI-type discoloration detonators, when the diameter of the fire transfer hole changes within the range of 0.6-6.4mm, as the diameter of the fire transfer hole increases, both the ignition peak pressure and the ignition impulse increase monotonically. When the diameter of fire transfer hole varies from 0.2 to 0.6mm, the two basically remain unchanged
