1·The fuze safety system is not just an absolute sub-system in fuze, and is not equivalent to safety and arming device.
引信安全性设计是引信的核心技术之一，引信安全系统是引信安全性设计的主要体现形式。
2·Based on the characteristic analyses of fuze arming device, a special acoustic transmission device is selected to obtain the state signal of the device.
根据引信保险机构系统特性分析，选择驻极体传声器作传感器，从而获得引信保险机构的状态信号。
3·The frame of electro-mechanical safety and arming device (S&A) is established, and the electro-mechanical S&A for the mortar shell fuze is designed at the end of the paper.
最后构建了引信机电式安全系统的系统框架，并结合迫击炮弹引信开展了机电式安全系统的设计。
