本文比较系统地讨论了高速电子开关用于系统回避技术的几种典型方法,并就这些方法作了简要性能比较。认为,优化的f方案比较适合于所涉及的应用环境。同时,文中较详尽地介绍了实现f方案的具体方法和各种电路加固和工艺加固措施,以及一系列关键技术,提出了利用预辐射手段提高开关抗中子辐射能力的设想。 This article systematically discusses the high-speed electronic switches used in system avoidance techniques of several typical methods, and made a brief comparison of these methods performance. That the optimized f program is more suitable for the application environment involved. At the same time, a detailed description of the specific methods to achieve the f program and a variety of circuit reinforcement and process reinforcement measures, as well as a series of key technologies, put forward the idea of ​​using pre-radiation means to improve anti-neutron radiation switching capabilities.
