提出并研制了一种新型电力系统暂态故障模拟再现系统。该系统通过将系统发生故障时故障录波器录下的数据转换为符合IEEE的COMTRADE格式文件，经数据处理软件进行分析后由电脑并口送入多功能继电保护测试仪，最终由测试仪还原成故障时的ＰＴ、ＣＴ二次侧电压、电流信号。该系统对继电保护装置参数整定、事故原因查找及分析等有辅助作用。-proposed and developed a new type of power system transient fault simulation and reconstruction system.IEEECOMTRADE. The system of relay device parameter setting, the cause of the accident investigation and analysis of a supporting role.

python神经网络书中的代码，非常使用的学习资料(the code in<python nerual net>, this is trully useful)

A boost converter (step-up converter) is a DC-to-DC power converter that steps up voltage (while stepping down current) from its input (supply) to its output (load). It is a class of switched-mode power supply (SMPS) containing at least two semiconductors (a diode and a transistor) and at least one energy storage element: a capacitor, inductor, or the two in combination

JS俄罗斯方块完美注释版，今天终于用了大约4个小时写出来了. 其中在涉及到方块变形的时候还咨询了 　　 同学来帮忙; 个人觉得难点有这么几个: 　　 1: 边界检查, 不多说, 想通了就行 　　2: 旋转, 还是数学上的方法, 一个点相对另外一个点旋转90度的问题. 　　3: 让整个程序在点开始之后, 怎么让它一直自动的运行下去. 我以前一直没有做完, 　　主要是因为没有想清楚到底要用一个什么机制让游戏自动运行下去, 这个过程可以这么理解: 　　用户点开始->构造一个活动图形, 设置定时器, 每次向下移动后, 都检查是否触底, 如果触底了, 则尝试消行, 完了之后再构造一个活动图形, 再设置定时器.

说明：  基于FFT的谐波检测,采用快速傅里叶算法后得到原始波形中各次分量的频率和幅值特性，从中可以直接观测出各次谐波分量的频率和幅值信息. 程序1采用快速傅里叶算法后得到原始波形中各次分量的频率和幅值特性图 程序2输入信号经过FFT变换得到的频谱特性图 程序3对输入信号进行采样，应用一维小波变换函数进行三层小波分析(Based on FFT harmonic detection, the frequency and amplitude characteristics of each harmonic component in the original waveform are obtained by using fast Fourier algorithm, from which the frequency and amplitude information of each harmonic component can be directly observed In program 1, the frequency and amplitude characteristics of each component in the original waveform are obtained by using the fast Fourier algorithm The spectrum characteristic diagram of program 2 input signal through FFT transformation Program 3 samples the input signal and applies one-dimensional wavelet transform function to three-level wavelet analysis)
