代码说明：

一种积分变换，它来源于函数的傅里叶积分表示。积分（1）称为? 的傅里叶积分。周期函数在一定条件下可以展成傅里叶级数，而在（－∞，∞）上定义的非周期函数?，显然不能用三角级数来表示。但是J.-B.-J.傅里叶建议把?表示成所谓傅里叶积分的方法。(An integral transformation derived from the Fourier integral representation of functions. The integral (1) is called the twin Fourier integral. The periodic function can be extended to Fourier series under certain conditions, while the non-periodic function twin defined on (-, u) obviously cannot be expressed by trigonometric series. But J. -B. -J. Fourier suggested that twins be represented as so-called Fourier integrals.)

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++为图片增加水波鼠标跟随效果的特效蒙版，动态的图片蒙版，鼠标在图片上晃动，会随机出现水波效果，晃动的越快，水波越多哦。用户还可以选择火焰和等离子效果，类似于给图片增加了一层蒙版的效果，很给力。
