雷电作用下机载无线通信模块电磁耦合仿真研究

open access: yesDianci bileiqi
无人机在遭受雷击时机载的无线通信模块将面临严重的损伤威胁,亟须对机载无线通信模块的雷电电磁耦合进行深入研究。文中进行了机载无线通信模块的雷电电磁耦合分析及仿真,仿真结果表明,“前门”耦合主要的耦合途径为天线,由电磁环境频率以及天线工作频率决定。“后门”耦合方式主要的耦合途径为机壳以及线缆,机壳屏蔽层极大衰减了雷电电磁能量,但线缆上会产生较大的感应电流和电压。电磁能量进入无线通信模块主要通道为线缆。本研究为机载无线通信模块的电磁损伤特性试验及研究提供了理论支持和仿真依据。

论革命的“三结合”

open access: yesGaoya dianqi, 1967
毛主席提出,在需要夺权的那些地方和单位,必须实行革命的“三结合”的方针,建立一个革命的、有代表性的、有无产阶级权威的临时权力机构。这个权力机构的名称,叫革命委员会好。这是无产阶级革命派夺权斗争取得胜利的政治保证和组織保证。无产阶级革命派要正确地领会这个方针,正确地执行这个方针。革命的“三结合”的临时权力机构,要由真正代表广大群众的革命群众组織的负责人、人民解放军当地驻军的代表、革命领导干部祖成。三者缺一不可 ...
