电雷管同步性高速摄影研究

HIGH SPEED PHOTOGRAPHY STUDY ON INITIATION SYNCHRONISM OF ELECTRICAL DETONATORS

应用高速扫描摄影拍摄了表征电雷管特性的随机变量,如作用时间,得到电雷管同时起爆爆炸同步性(极差)。研究了雷管母体标准差与样本极差间的函数关系。在已知母体雷管标准差的情况下,可以确定由n个雷管组成的样本的极差不超过某一指标的概率;或在样本的极差不超过某一指标概率的条件下,可以确定母体的标准差。这在科研生产和使用中具有重要的应用价值。本方法的测量误差小于或等于0.03μs。

High speed photography was used to determine the random variables of electrical detonator properties such as action time,and their synchronism was character- ized with the initiation time difference(ITD)obtained therefrom.Studying the func- tional relation between the batch detonators' initiation synchronism standard deviation (ISSD)and the samples'ITD shows,when the ISSD of the batch detonators is given, the ITD of samples consisting of n detonators will not exceed the stipulated probability. On the contrary,if the samples'ITD does not exceed the stipulated probability,the ISSD of batch detonator can be found out,and the measuring error is less or equal to 0.03μs.This method is valuable for both research and application of electrical detona- tors.
