鉴于直列式安全起爆系统在外界恶劣电磁环境下以及弹上电气工作时产生的涌浪电压、静电及电磁辐射等干扰因素,采用隔离设计、屏蔽电子线路、瞬态电压抑制器等方法减少电磁辐射、电磁干扰,改善了直列式安全起爆系统的电磁兼容性;并根据国军标电磁安全性评估方法,对直列式安全起爆系统在包装、裸露、工作状态下进行了电磁安全性测试分析。试验结果表明,通过电磁兼容改善后的直列式安全起爆系统在电磁辐射(EMR)、电磁干扰(EMI)、静电放电(ESD)环境危害中具有高安全性,完全满足大型战斗部对起爆技术的要求。

Aiming at the problem of interference occurred in in-line electronic safety and arming system, which was caused by surge voltage, electrostatic and electromagnetic radiation in harsh electromagnetic environment in the outside world, as well as on-line of bomb, the methods such as isolation, shielding the circuit, transient voltage suppressors and other were adopted, the electromagnetic radiation (EMR) and electromagnetic interference (EMI) was reduced effectively, which improved electromagnetic compatibility of in-line electronic safety and arming system. Meanwhile, according to the military standard, the electromagnetic safety of in-line electronic safety and arming system was tested and analyzed under the package, nudity and working state condition. The experimental results showed that the improved in-line electronic safety and arming system has high safety in hazards of EMR, EMI and electrostatic discharge(ESD), which can meet with the requirements of large warhead.

In this paper, the laser initiation system and the build-in-test(BIT) system were introduced, the upper safety limit of test power for single-wavelength and double-wavelength BIT system was analyzed, the no-fire power test of initiator was conducted with CW laser input model by using the Neyer D method, as well as the upper safety limit of test power for initiator in single/double BIT system was specified. Meanwhile, the rationality of designed safety limit was also verified. The study provided the reference for design of BIT system.

非电起爆系统在爆破工程中广泛应用，工业雷管如何安全、可靠起爆导爆管至关重要。本文开展了8号工业雷管起爆导爆管能力的模拟实验，分别对雷管正、反向起爆导爆管情形，不同捆扎约束力情况下导爆管引爆概率进行了研究，并对雷管起爆导爆管的可靠距离和不破坏临近导爆管的安全距离进行了研究。实验结果表明：（1）雷管正、反向起爆导爆管对起爆概率影响不大，但正向起爆存在金属射流或破片切断导爆管的可能；（2）导爆管的捆扎约束力越大，有效起爆导爆管数量越多，起爆概率越大；（3）雷管起爆导爆管的可靠距离≤1cm，不破坏临近导爆管的安全距离≥9cm。本文的实验结果与分析对工程爆破中非电起爆网络起爆可靠性、安全性分析等方面具有一定的参考价值。

Non-electrical initiation system has been widely applied in blasting projects. So how to keep the safety and reliability of industrial detonators initiating the nonel tubes becomes very important. The article carried out the simulation experiment of the nonel tubes initiated by industrial detonators of series 8. The experiment investigated the initiating probability under the condition of the front and back shooting methods and under the condition of different enlacing forces. Also, the reliability distance of initiating the nonel tubes and the safety distance of not destroying the nonel tubes were put forward. The experimental results showed that:(1) the initiating probability revealed a smal difference when applying the front or back shooting methods. But the front shooting method may exit the thing that the metal jet and detonator lfyer cut off the nonel tubes;(2) the bigger enlacing force of the nonel tubes was, the bigger number of effective initiating nonel tubes was, that is to

The number of vehicle road traffic accidents increases year by year, while people buy more and more cars. The emergence of the restraint system hugely saves lives. The safety airbags, which is the last guarantee in the restraint system, undoubtedly attract people''s attention. However, every sword has two blades. The safety airbags also bring suffer to its user, leading to doubt of them. The writer demonstrates some misunderstanding of customers to the airbags and analyzes the reason to misfire of airbags and the situation when the airbags atc is safe. Moreover, detailed description of the function of airbags in the restraint system is deployed.
