说明：  30章51单片机入门教程，让你轻松学会单片机，不用老师，自学也能学会(30 Chapter 51 MCU introductory tutorial, allow you to easily learn the microcontroller without the teacher, can learn to self-)

基于SVM与人工神经网络的车牌识别算法，使用了OpenCV的图像处理函数，在VS2013 + OpenCV 2.4.9平台上实现(SVM algorithm based on license plate recognition and artificial neural network, using OpenCV image processing function, implemented on VS2013+ OpenCV 2.4.9 platform)

一个中国剩余定理的简单算法,密码学基础算法(Chinese Remainder Theorem a simple algorithm, based on cryptography algorithm)

本项目是基于Cortex-M3 的地沟油快速检测装置，旨在实现“地沟油”快速，现场检测。MCU控制可编程的直接数字频率合成器（DDS）产生正弦激励信号，经过可变增益放大器（VGA）和低通滤波器（LPF）作用于食用油阻抗传感器（实验室制作）信号经过仪器放大器送入微控制器（MCU）的模数转化（ADC）通道，MCU对采集的信号通过快速傅里叶变换（DFT）处理，实现食用油阻抗与相角的检测；USB和以太网接口，可与计算机通讯，以便对采集的数据进行存储和分析。(The project is based on the Cortex-M3 waste oil rapid detection device designed to achieve " waste oil" rapid, on-site testing. MCU control programmable direct digital frequency synthesizer (DDS) generates sinusoidal excitation signal through a variable gain amplifier (VGA) and a low-pass filter (LPF) acting on the oil-impedance sensor (lab produced) to send signals through the instrumentation amplifier into the microcontroller (MCU) modulo conversion (ADC) channels, MCU signal acquisition via Fast Fourier Transform (DFT) processing, oil resistance and phase angle detection USB and Ethernet interfaces, and computer communication, in order to collect data for storage and analysis.)

语法分析，和编译原理课程配套，可以输出错误原因。输入通过读文件。(Syntax analysis, and compiler theory course package, you can output the wrong reasons. Input by reading the file.)

说明：  In c++ risks is a reference to a variable which exists i.e. one 2nd name for the same variable. This program is broken up into functions.露the function hand constitutes the entrance point of the program, firstly there is the function message which us affiche hello , and the second function produced 露procedure affich_calcul, one declared the prototype and one it definite after one made the call has this function.
