自己编译的非常强大的西门子S7系列通信库，可以摆脱OPC的收费困扰(To compile a very powerful Siemens S7 series of communications library, you can get rid of troubled OPC charges)

有源滤波器使用在光伏中 可以改写到双馈式风力发电机中使用(Active filters can be rewritten using the PV to double-fed wind turbines use)

说明：  idl教程的随书程序，可以帮助你学习点语言(idl tutorial with the book can help you learn the language point)

CNGP API 开发实例，本程序包括了CNGP的开发说明和实例-WWW API development example, the process includes the development of WWW description and examples

心电信号处理Cardiac-frecuency-and-ECG-signal-denoising-by-EEMD-master(ECG Signal Processing)

说明：  一种很好的针对非平稳信号的一种算法，他可以有效是区别各种调治方式，是对以前的时间平滑方法的一种改进形式，希望对大家有用(A good response to non-stationary signals in an algorithm, he can be an effective way to distinguish between the various modulating is a smoothing method before the time of an improved form, in the hope that useful)
