摘　　要：针对M739引信头部机构的基本结构与特性,分析其头部触发机构的发火原理,提出发火模式种类的判别方法。结合某型引信的具体参数,计算其对钢板、胶合板和地面三种不同目标介质射击时的碰击力,分析碰击力、防雨机构静态下移抗力及支筒图定抗力对发火模式的影响。试验结果表明,该发火模式判别方法适用于M739系列引信。According to the basic structure and characters of the M739 fuze nose mechanism,the detonation principle of the head impact mechanism was analyzed and the mode of fuze＇ s detonation was presented. Based on the parameters of a certain fuze, the anti-force of target media according to different targets was calculated. The influence of the anti-force of target media, the anti-inertia force of rain-proof sleeve and standard anti-inertia force of firing pin support for the modes of fuzes＇ detonation was analyzed. The test results show that the decision method of fuzes＇ function mode is suitable and effective for the fuze of M739 series
