登陆界面。可以设置账号密码。输入正确后方可进入主程序。(this is a load programme,with which you can set account number and passwords.and conrect them ,you can join in the main programme.)

说明：  汇川plc数据采集，基于modbus协议(Data acquisition of Huichuan PLC based on Modbus Protocol)

说明：  对基于模块化多电平换流器作为逆变器采用最近电平逼近调制模式时的谐波分量进行分析，选取逆变器上、下桥臂电流，相间环流及交流输出电压波形作为研究 对象，通过理论推导出上、下桥臂电流主要具有直流分量、基波分量及 2 次谐波分量;相 间环流仅含有偶次谐波;交流输出电压波形仅含有奇次谐波。(Based on the analysis of the harmonic components of the modular multilevel converter when the closest level approach modulation mode is adopted as the inverter, the upper and lower bridge arm currents, inter phase circulation and AC output voltage waveforms of the inverter are selected as the research objects, and the current of the upper and lower bridge arm mainly includes DC component, fundamental component and second harmonic component; There are only even harmonics in the inter phase circulating current and odd harmonics in the AC output voltage waveform.)

此方法实现了对窄带相干信号的估计，仿真结果显示了有效性(CRB_2)

《Python核心编程》。著名的自由软件作者Eric Raymond建议人们从Python开始学习编程。这的确是一个中肯的建议，对于那些从来没有学习过编程或者并非计算机专业的编程学习者而言，Python是最好的选择之一。(Python is an object-oriented explanation of computer programming languages, is a powerful and well-size-fits-all language, has been more than a decade of development, maturity and stability. Python scripting language with the most rich and powerful class library, enough to support the vast majority of day-to-day applications. )
