摘　　要：为了研究超细LLM-105炸药的短脉冲起爆特性,设计了两种参数的飞片起爆系统,在对两种飞片系统驱动飞片速度分析的基础上,采用较佳匹配系统进行了超细LLM-105炸药的发火阈值测试。试验结果表明:两种飞片系统中飞片速度随着输入起爆电流的增加而增加,但是大尺寸飞片对输入电流的变化更加敏感;在相同起爆条件下,大尺寸飞片获得的最大速度一致性较差,这与尺寸增加,受空气阻力影响更明显有一定关系;采用飞片速度较高的飞片系统进行超细LLM-105炸药起爆阈值测试,得到超细LLM-105炸药的50%发火阈值电流为2.14kA,与HNS-Ⅳ相差不大。由此表明,超细LLM-105炸药作为冲击片雷管始发药应用是可行的,即能满足冲击片雷管钝感化要求,又不会对引爆系统的能量提出过高的要求,符合目前冲击片雷管低能、钝感的发展趋势。The two types of flyer were designed to study short duration pulse shock initiation characteristics of ultrafine 2,6-diamino-3,5-dinitropyrazine-1-oxide（LLM-05）. The firing testing of ultrafine LLM-105 is implemented by D-optimal method based on analysis of flyer velocity. It is found that the flyer velocity is increasing as increasing pulse current. The velocity is sensitive to current variety for large dimension flyer by contrasting small dimension flyer. The inferior velocity consistency for large flyer exists, which has the relationship with air resistance. The air resistance is increasing with improvement of flyer dimension. The 50% firing current, of ultrafine LLM-105 is 2.14 kA by small dimension flyer, which is almost equal to initiating threshold of HNS-Ⅳ. It is indicated that ultrafine LLM-105 would be used for initiation explosive at slapper detonator. The LLM-105 explosion system will satisfy the development trend of slappde detonator, namely, desensitization, low input energy, and so on.
