对弱链技术的国内外研究现状进行了介绍,根据弱链的作用和火工品的特点,以冲击片雷管为例对弱链在火工品中可能的实现途径进行了分析。通过分析可以发现,采用在异常环境中(热或力冲击)性能可以发生改变的材料作为火工品的关键部件,可以在异常环境中使火工品不能可靠发火,保证了系统在异常环境下的安全性。
According to the function of weak chain and the characteristics of pyrotechnics, taking the impulse detonator as an example, the possible ways to realize weak chain in explosive are analyzed. Through the analysis can be found, the use of materials in abnormal environments (thermal or impact) can change the properties of materials as a key component of the pyrotechnics, pyrotechnics in anomalous environment can not be reliably angry, to ensure that the system under abnormal conditions Security.
