本文通过对男性和女性声音的语音特征的研究，发现男女声的基音频率存在较大的差异，并设计了基于基音频率分析的男女声识别系统。男女声识别系统由以下三个模块电路构成：话筒放大器，低通滤波器，半波整流电路，单片机测量控制模块。话筒放大器采用NE5532P音前置芯片，对语音信号进行放大；八阶低通滤波器MAX293完成基音信号的提取；单片机STC12C5410AD实现频率测量和控制输出功能。经仿真与电路实测，男女声的识别效果良好。(In this paper, the voices of male and female voice characteristics of the findings of a study of the fundamental frequency of the sound of men and women there is a big difference, and the design of frequency analysis based on the pitch of the voice recognition system for men and women. Voice Recognition System for men and women from the circuit the following three modules: the microphone amplifier, low-pass filter, half-wave rectifier circuit, single-chip measurement control module. NE5532P sound using the microphone pre-amplifier chip amplification of voice signals eight MAX293-order low-pass filter to complete the extraction of pitch signal STC12C5410AD single-chip realization of the frequency of measurement and control output. By circuit simulation and measurement, the identification of male and female voices well.)

VC++枣子穿纽游戏源码，类似扫雷游戏的界面，不过玩法有点不一样，游戏源代码在vc++6下编译通过，你应该通过源代码能看出些玩法来。
相关资料：在本游戏中，你将作为一名裁缝，将尽可能多的纽扣穿成一个闭合的路线。游戏初始有 15 个纽扣，随着时间的增加，纽扣数目也增加，当达到70个时游戏即结束。只能在有纽扣的点穿线，且只能在水平方向或竖直方向穿线。线可交叉，但有纽扣的点不能交叉连接。
透露点秘诀：要尽可能使连线长且该连线上的纽扣数多。(VC++ source code dates to wear new game, the game interface similar to mine, but a bit different from playing the game in the source code to compile under vc++6 passed through the source code you should be able to see more options. Relevant information: in this game, you will serve as a tailor, will be wearing buttons as much as possible into a closed line. Game initial 15 buttons, an increase over time, increase the number of buttons, when the 70 hours to reach the end of the game that is. Buttons can only point in the threading, and only in the horizontal direction or vertical direction of threading. Lines cross, but the buttons can not be cross-connect point. Point revealed the secret: To the extent possible, so long and the connection to connect on a few more buttons.)
