说明：  意法半导体400W大功率BOOST PFC电路。双管并联。(The board implements a 400 W, wide-range mains input, PFC pre-conditioner suitable for ATX PSU, Flat screen displays, etc. To make possible the use of a low-cost device like the L6562A at this power level, usually prohibitive for TM PFC, the chip operates with Fixed-Off-Time control. This allows continuous conduction mode operation, normally achievable with more expensive control chips and more complex control architectures.)

说明：  webstocket服务后台服务，用于和小程序对接(webstocket service to use wechat mini program)

说明：  模拟可视化大数据交互动态模板网页前端，对大数据交换进行了模拟，并无实际处理数据能力，仅作为模拟演示。(Simulation and visualization of big data interactive dynamic template web front end)

mwc基于stm32的飞控代码baseflight,对初 学者有很大的帮助，这个适合航模爱好者，难度还是有点大大的，具体的可以去网上找mwc基于AVR的代码

基于matlab软件，采用随机四参数法生长法构建不同类型的多孔介质模型(Production of Porous Media Model by Random Four-parameter Method)

说明：  用H无穷控制，对不稳定系统进行鲁棒控制。本人用车载DVD作了仿真试验，效果较好(H infinite control of instability robust control system. I made a car DVD simulation test, the result is better)

说明：  北大青鸟，JS+JQuery内部测试机试题(beidaqingniaojsneibuceshiti)
