对利用录音设备对手机、电话等按键式密码输入终端进录音盗取银行卡密码的不法行为进行技术分析，利用MATLAB软件编程对按键式密码输入终端的按键音进行音频分析，基于短时能量和过零率对所采集的音频文件进行端点检测，提取出单个拨号音，然后对处理后的音频进行频谱分析、对比，从而识别按键式密码输入终端的按键音。(On the use of recording equipment on the phone, telephone touchtone input terminal password into the recording steal bank card passwords wrongful conduct technical analysis using MATLAB software programming for touch-tone touchtone password input terminal for audio analysis, based on short-term energy and zero-crossing rate of the acquired endpoint detection audio files, extract single dial tone, and then processed audio spectrum analysis, comparison, to identify key tone touchtone password input terminal.)

matlab教学或自学用的PPT教程，内容肺腑，包含实例教学，很实用(matlab or self-teaching tutorial with the PPT, the contents of the heart, including examples of teaching, very practical)

本文实现二级倒立摆数学模型的推导，状态空间描述以及状态反馈和状态观测器的实现！比较有无状态观测器对系统运动的影响！(This paper presents two mathematical models of the derivation of the inverted pendulum, the state-space representation, as well as state feedback and state observer to achieve! Comparison of availability of state observer on the system impact of the movement!)

说明：  通过运动尺寸计算，绘制四连杆机构的运动，并动画演示(Size calculated by movement, drawing four Linkages)

Emergency System in Power Substation

自己编写的程序，在光谱数据处理上可以实现截回波以及傅里叶变换功能(I have written procedures, the spectral data processing can be achieved as well as truncated Fourier transform function echo)

实现DBF运算的具体的仿真程序，可帮助新人参考 (the simulated program to implement DBF )

in this program, the sparse representation of data was calculated.
