【摘要】 文对我国延期雷管秒量精度低的问题,从延期药剂组成及制造工艺、点火药及点火药头作用、延期雷管结构及外界环境条件的影响等方面进行了综述,认为主要影响因素是由延期药剂为主构成的延期元件,提出在发展电子延期技术的同时,仍有必要做好延期药优化和加工技术研究与应用。更多还原

【Abstract】 As for the low time accuracy of our delay detonators, the paper comments on from several aspects,including the components and manufacturing technique of delay agent,the function of ignition charge,the structure of delay detonator and the influence of external environment.It is deemed that the major influencing factor is the delay element mainly composed of delay agent,and it is still necessary to optimize delay charge,study and apply processing technique broadly,while developing electronic delay technique.更多还原
