基于短时能量和短时过零率来实现语音端点检测。也称为双门限比较法，是一种传统的 语音端点检测方法。现在已经有研究人员提出若干其他更加高效和有效的检测方法，但 是这个方法不失为一种最简单的方法，可以通过程序来获得语音端点检测的感性认识和 体会。内的程序读取WAV文件，程序附有详细的使用说明和注释，以及若干测试用的语音文件。(Based on the short-term and short-term energy to achieve zero rate of voice activity detection. Also known as dual-threshold comparison method, is a traditional method of voice activity detection. Researchers now have made a number of other more efficient and effective detection methods, but this method may be one of the most simple way to get through the process of voice activity detection and the experience of perceptual knowledge. Procedures within the WAV file to read, procedures with detailed instructions and notes, as well as the voice of a number of test documents.)

UHF读写器读写器简介 本产品具有多协议兼容、体积小、读取速率快、多标签识读、圆极化天线对标签没有方向限制、防水型外观设计等优点，可广泛的应用于各种RFID系统中，典型的应用场合有：  (UHF reader reader Introduction The product is compatible with multi-protocol, small volume, read rate, and multi-tag read, circularly polarized antenna on the label does not limit the direction, waterproof design, etc., can be widely used in a variety of RFID systems, typical applications are:  )

C++经典语法与应用，类的编写与应用，构造与析构函数，函数的重载，类的继承，函数覆盖，基类与派生类的构造函数、析构函数先后调用顺序，如何在派生类构造函数中向基类的构造函数传递参数，this成员变量，类型转换的内幕，虚拟函数与多态性,引用和指针的变量的区别与共同处。VC工程的编译原理与过程，将工程中不同的类拆分到不同的原文件中，每一个类由一个.h和.cpp文件共同完成，头文件重复定义问题的解决，培养了学员良好的编程习惯，也为以后分析MFC Appwizard生成的工程奠定了良好基础。(Classical syntax and application of C++, class preparation and application of the constructor and destructor, function overloading, class inheritance, function coverage, the base class and the derived class constructor, destructor has invoked the order, how in the derived class The parameters passed to the constructor of the base class constructor, the this member variable of the insider type conversion, virtual functions and polymorphism, difference between reference and pointer variables in common. VC compiler theory and engineering process, the different classes in the project is split into the original file, and each class by one. H. Cpp file jointly, header files define the solution of the problem is repeated, cultivate good students programming habits, but also laid a good foundation for later analysis the MFC Appwizard generated engineering.)
