三相整流器SPWM调制模块应用于三相两电平逆变器主电路(Three phase rectifier SPWM modulation module is applied to three phase two level inverter main circuit.)

实现双有源桥变换器 单移相控制 ，参数已经设置好可以直接运行。(The single phase shift control parameters of dual active bridge converter have been set up and can be directly operated.)

机器学习之文本分类，有代码，语料库，分词 python语言(Machine Learning Text Categorization, Code, Corpus, Word Segmentation Python language)

the document is a datasheet of Mifare 4K chip, and is useful to understand the Mifare applications

这是空载合闸的matlab/simulink的模型，能够较好的观察到空载合闸的电流畸变波形，对初学者能够有更好的帮助。(This is a matlab/simulink model with no load switching. It can better observe the current distortion waveforms of no-load switching, which can help the beginners better.)

农村水电费记帐录入，统计汇总，打印输出收费单据。可预存费用，也可欠费统计。-Rural utilities account entry, statistical summary, printouts charging documents. Costs can be stored can also be Arrearage statistics.
