冲击波压力损失与炸药的爆炸压力有关、可以通过计算炸药的密度和爆速来估算。因此、炸药的冲击波压力损失的测定可以通过实验引人一些诸如温度、静态和动态预压及导爆索支线等变量来确定The shock pressure loss is related to the explosive's detonation prepressure, which can be estimated by knowing the density and detonation velocity of the explosive. Therefore, the SLF for a test explosive can be experimentally determined by introducing in the test certain additional variables, such as temperature,static and dynamic pre-compression and detonating cord downline
测试系统的静态特性测试系统的静态特性是指被测量处于稳定状态时测量系统的输出与输人的关系,通常用非线性、灵敏度和回程误差等指标来表征static characteristics of a measuring system
炸药感度根据所受外界能量作用的不同、可分为冲击波感度、撞击感度、摩擦感度、静电感度、雷电感度或其他能量形式的感度The stimulus to which an explosive is exposed must be included in any reference to the sensitivity, whether shock, low-velocity impact, friction, electrostatic charge, lightning, or other source of energy
通常用于爆破设计和破碎模型中的这些参数、都是静态的、而非动态性质、只不过在用于模型时经验因素弥补了这种反常The parameters that are generally used in blast design and fragmentation modeling are the static rather than the dynamic properties, but empirical factors used in the models compensate for this anomaly
静电的产生除电引起静电外,固体颗粒的运动,特别是在干燥条件下的颗粒运动,也将产生静电。例如: 1. 在压气装药过程中,能够积累电能的部位有3处,一是操作者身上,二是装药器及其附属设备上,三是炮孔内和雷管脚线上。 2. 失作人员穿化纤衣服source of static electricity
静电的危害静电表现为高电压、小电流,静电电位往往高达几千伏甚至上万伏特。静电之所以能够造成危险,主要是由于它能聚集在物体表面上而达到很高的电位,并发生静电放电火花。这种储存起来的静电荷可能通过电雷管导线向大地放电,而引起雷管爆炸harmfulness of static electricity
静电的防治1. 在压气装药系统中要采用半导体输药管。 2. 对装药工艺系统采用良好的接地装置。(3)采用抗静电雷管。(4)预防机械产生的静电影响prevention of static electricity
