如果你满足以下条件： ? 会使用电脑，但从来没写过程序； ? 还记得初中数学学的方程式和一点点代数知识； ? 想从编程小白变成专业的软件架构师； ? 每天能抽出半个小时学习。 那么你就能学会python(If you meet the following criteria: Can use a computer, but never write a program; Remember junior high school math equations and a little algebra; Want to go from programming whiz to professional software architect; I can spare half an hour to study every day. Then you can learn python)

说明：  采用Laser - PVDF 实验系统对纳米AlP/ SiO2 中激光超声信号进行采集. 利用小波的多尺度分解、重 构和消噪功能,提取出直达波及其反射回波,测量了时间间隔和纳米AlP/ SiO2 的纵波声速. 结果证明小波变换 的方法能有效地处理复杂激光超声信号.(Using Laser- PVDF experimental system of nano-AlP/SiO2 Laser ultrasonic signal acquisition. Using wavelet multiscale decomposition, reconstruction and de-noising function, extracted from direct wave and its reflection echo measured time interval and nano-AlP/SiO2 of the longitudinal wave speed of sound. wavelet transform results show that the method can effectively deal with the complexity of laser ultrasonic signals.)

现代控制系统，Dorf.R.C及Bishop.R.H的大作，现在都到第十三版了。从事控制工程的工程师都应该好好读读这本书，讲解清晰，并附有大量工程实例，之前在学校没学懂控制理论，是在工作过程中自学的，主要就是这本书吧，控制工程人员的基础。 包含课本源码（源码从网上都好找），以及中文PPT（这个网上不好找的）。不愿花钱买的，也可以上网找找电子书，中文扫描版或英语版电子书。(Modern control systems, Dorf.RC and Bishop.RH s masterpiece, now to the 13th edition of the. Engineers involved in control engineering should be a good read this book to explain clearly, together with a large number of engineering practice, did not learn in school before the control theory, self-learning process at work, and mainly the book a, control engineering staff base. Includes textbooks, source (source code from the Internet are all easy to find), and Chinese PPT (not easy to find in this online). Unwilling to spend money to buy, you can also look for books online, the Chinese version or English version of book scanning.)

本文首先介绍了有源电力滤波器的基本结构和工作原理，并对一些常规的谐波电流检测方法的优缺点进行了比较。其次，针对传统的谐波电流检测方法的缺陷，提出将神经网络与基于噪声抵消原理的自适应谐波检测相结合，利用径向基函数运算量小、收敛快、无局部极小值等优点，构造了一种基于径向基函数神经网络的谐波电流检测方法，仿真结果表明该检测方法具有很好的动态响应及畸变电流检测精度。最后，设计了一套实验系统，对本文所采用的系统方案进行了实验验证。仿真表明，本文所采用的有源电力滤波器检测系统方案切实可行，能够较好地实现动态检测谐波和无功功率的目的。 (This paper, firstly, introduces the basic structure and principle of APF, and then makes comparison among some conventional harmonics detections methods. Secondly, contraposes the limitation of the traditional harmonic current detecting method based on neural network, presents the method that combines the neural network and auto adaptive harmonic current detecting method based on the principle of noise each other eliminating.As the characteristics that are small calculative quantity, fast converge, without local minimal point of Redial Basis Function (RBF), this dissertation forms a new harmonic current detecting method based on RBF. The simulation results show that the method has many advantages, such as good dynamic response, high accuracy. At last, A system is designed to verify the proposed APF scheme .The results of simulation show that the proposed APF scheme is practical and can detect harmonics and reactive power effectively. )
