本实验语音库为免费的柏林情感语音库，其采样频率为16KHZ，16bit量化。该语音库共有500 句情感语音信号，分别由十名专业演员(5 男，5 女)在不同情感状态下（高兴、愤怒、平静、悲伤、害怕、厌烦、憎恨）朗读十句不同文本的德语组成。本实验选取其中的部分情感（高兴、愤怒、悲伤）加以识别。仿真实验环境为MATLAB7.0。
实验选取的情感特征为短时平均能量、短时平均幅度、基频和短时过零率。为了降低不同人在表达不同情感时的个人差异造成的影响，本文实验过程中将提取的情感特征进行归一化处理。归一化采取将同一个人的三种情感语音信号的情感特征放在一起归一化处理，并将归一化后的情感特征作为KNN分类器的训练样本和测试样本。
该实验使用了传统的KNN算法和改进算法两种识别方式，通过实验结果对比了各自的特点。
(This experiment YuYinKu for free Berlin YuYinKu emotion, the sampling frequency for 16 KHZ, 16 bit quantification. The YuYinKu 500 words of emotional speech signal, respectively by ten professional actors (5 male, five female) in different emotional state (happy, anger, sadness, fear, calm, bored, hate) read ten sentences in different text of the German. This experiment selection of part of the emotions (joy, anger, sadness) is recognized. The simulation experiment environment for MATLAB7.0.
The selection of emotional characteristics for short-term average energy, short-term average amplitude, frequency, and the short zero rate. In order to reduce the different people in different emotional expression of the impact of individual differences, the experiment process will extract emotional characteristics is normalized. The normalized will take the same three kind of emotional speech signal emotional features normalized put together, and after the normalized the emotional characteristics)

MyHotKey
利用系统热键可以方便用户的操作，比如经常使用的Alt + Tab可以快速切换窗口；Crtl + Alt +
Delete键可以调出Windows任务管理器或重启机器；oicq软件也会注册系统热键方便用户的操作，等等。本程序就注册一个系统热键Alt + Z，在应用程序执行的任何时候只要按下该热键就会弹出一个消息对话框。
(system hotkeys can use user-friendly operation, For example, the regular use of the Alt-Tab window can quickly switch; Crtl-Alt-Delete keys could be released Windows Task Manager or the reopening of machinery; oicq software registration system hotkeys will be user-friendly operation, and so on. The procedure for registering a system hotkeys Alt Z, Application procedures for the implementation of any time by pressing the hotkey will pop up a message box.)

斐波那契数列
非递归斐波那契数列，简单。在进行数据结构课程学习之前，并没有非常经常敲代码的习惯，也只会简单的语言来实现一些简单的功能。在一学期的学习后，不仅写了很多代码，也通过学习知识极大地提高了自己程序的效率，让人感觉到获益匪浅。
