现在C++有效编程的基本技巧和方法，是第一本介绍C++ 11 新版本的高效率编程的数据(Now the basic skills and methods of C++ effective programming are the first to introduce the highly efficient programming data of the new version of C++ 11.)

序自从1978年《C程序设计语言》出版以来，计算机界经历了一场革命。大型计算机变得更大；而个人计算机的能力可以和十年前的主流计算机相媲美。在这段时间中，C语言也在悄悄地改变，并且早已超出了仅仅作为UNIX操作系统的语言的范畴。(sequence since 1978 "C Programming Language" has been published, the computer industry has undergone a revolution. Large computers become bigger; But the personal computer and the ability to mainstream a decade ago comparable computer. During this period of time, C language is also quietly change, and already in excess of the UNIX operating system only as the language of the area.)

Digital Processing of Synthetic Aperture Radar Data

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.

说明：  锁相的意义是相位同步的自动控制,能够完成两个电信号相位同步的自动控制闭环系统叫做锁相环,简称PLL. 3种软件锁相的方法：指针归零法，先调频后调相法，调频调相同时进行法。(The meaning of phase-locked is the automatic control of phase synchronization. The automatic control closed-loop system that can complete the phase synchronization of two electrical signals is called PLL The 3 method of software phase-locked: pointer to zeros, first phase modulation after frequency modulation, frequency modulation phase modulation at the same time.)
