介绍算法的书及资料，有要学习算法的宝宝可以看看。(If you want to learn programming ,you can read this book.)

lte平台的链路级仿真,matlab代码实现(the simulink of the lte system)

python算法资料，提供了不少关于python的算法，值得一看。(Python algorithm data, provide a lot of Python algorithm, it is worth seeing.)

说明：  这是一本比较好的在linux下编程的书籍(c language of linux ,so study easy)

动态html(Dynamic html)

c++头文件浏览表(Table View)

JavaScript教程,很好用,内容很详细(JavaScript tutorials, useful, very detailed content)

Spring 源码深度解析，带您从底层了解Spring的原理。(Spring source code depth analysis, take you from the bottom to understand the principle of Spring.)

说明：  The objective is to present a nonlinear approach to design a suitable controller system for the photovoltaic (PV) single-phase grid-connected system. The system structure includes a PV generator, Boost converter, and DC-AC inverter coupled to grid network. A backstepping controller is developed to extract maximum point power tracking (MPPT), to regulate the DC bus voltage, and to generate a sinusoidal current into the grid in phase with grid voltage in order to achieve unity power factor. The stability of the control algorithm is demonstrated by tools of Lyapunov analysis. Simulations show that the proposed controller system completely accomplishes listed aims even under atmospheric conditions variation. Theperformance of the proposed controller has been validated by numerical simulation in MATLAB SIMULINK(The objective is to present a nonlinear approach to design a suitable controller system for the photovoltaic (PV) single-phase grid-connected system.
