摘要
本文介绍了高光敏炸药需要解决的四个问题，并用Ｎｄ激光器（脉冲宽度２５ｎｓ）测定了三种过渡金属配位化合物压制药住的临界起爆能，其中高氯酸·３（５）－氨基－４－肼基－１，２，４－三唑合铜（Ⅰ）药柱的起爆阈值约为４０ｍＪ／ｃｍ￣２，比叠氮化铅药柱的小约１０倍；还测定了高氯酸·５－肼－四唑合汞（Ⅱ）与透明的聚合物粘结制成的药片的临界起爆能Ｅ＿ｃ，所得结果：聚合物含量在１０～３０％范围内，Ｅ＿ｃ值逐渐缓慢降低；当超过３０％时Ｅ＿ｃ，值急剧升高。对配位化合物（Ⅰ）言，当聚合物含量为１０％时，Ｅ＿ｃ值随药片中炸药含量（ｍｇ／ｃｍ￣２）的增加而明显下降。结论认为这类过渡金属的配位化合物是对激光敏感的新型炸药；还提到这样的现象：厚药片与单质药片比，其起爆阈值较低，而薄药片则起爆阈值较高，从而表明药片有临界厚度的问题，即当药片薄于临界厚度，即使用于厚药片所需起爆能的１５倍，也不能被起爆，因此认为可能存在激光能在炸药内部产生定域（Ｌｏｃａｌｉｚａｔｉｏｎ）机理。
The laser initiation characteristics of light-sensitive explosive charges and sheets was investigated because they are of interest as possible objecta for study of the mechanism of fast reactions in condensed explosives. The complex salts of d-metals,i.e.,the transition elements with d-electron in their outer electron-shell,were taken as examples in the study.It was found that this class of salts is extremely sensitive to laser beam radiation,and the sensitivity of explosive sheets is clearly dependent on their thick-ness,which supposes that there must exist some mecLanism for localization of the laser energy inside the explosive sheets.
