对铅酸蓄电池，超级电容，锂电池，三者连接到dc-dc变换器升降压，然后采取不同的控制策略，恒压，恒流，恒功率控制，最后通过逆变器将直流变交流。matlab 仿真(For lead-acid batteries, supercapacitors and lithium batteries, the three are connected to the dc-dc converter to increase and decrease the voltage. Then, different control strategies are adopted to control the constant voltage, constant current and constant power. Finally, the dc converter is changed into an alternating current through the inverter.The matlab simulation)

讲述了现在机械故障诊断中用到的常用时频分析方法，如短时fft 魏格纳维尔分布 小波变换 HHT等，里面含有例子和详细说明，对初学者帮助很大。(Tells the now commonly used in mechanical fault diagnosis frequency analysis methods, such as short-time wavelet transform fft Wigner distribution HHT Louisville, etc., which contains examples and detailed instructions, very helpful for beginners.)

经典FDTD程序，仿真对象为horn天线，并且在域内设置电流源计算在空间内的散射场。(Classic FDTD procedure, simulation for horn antenna, and set the current source in the region in the space of the scattering field.)

说明：  伪随机码或称PN码，是扩频通信中不可缺少的一种序列。扩频通信，简单的说来就是通过一组相关性很强的伪随机序列，使原有的信号按照伪随机序列的特性出现。从波形上看，原有信号完全淹没于随机的噪声中，达到隐藏信号和抗干扰的目的。接受方只要有相同的伪随机序列，就可以通过伪随机序列很强的相关性将信号还原出来。而m序列，是扩频系统中最长用的伪随机序列。下面的代码就是基于matlab的生成m序列的代码，通过改变初始多项式的值，就可以生成不同阶数的m序列。(Pseudo-random code or PN code, spread spectrum communication is indispensable to a sequence. Spread spectrum communication, a simple to say that the adoption of a group of highly related to pseudo-random sequence, so that the original signal in accordance with the characteristics of pseudo-random sequence there. From the wave point of view, the original signal completely submerged in the random noise to hide the purpose of signal and interference. As long as the recipient has the same pseudo-random sequence, the pseudo-random sequence can be a strong correlation to restore the signal out. And m sequence spread spectrum system is the longest of the pseudo-random sequence used. The following code is generated based on m sequences of matlab code, by changing the value of the initial polynomial, we can generate a different order of the m sequence.)
