在文件qiexian.m中输入两个摩尔圆的坐标即可画出莫尔圆，并求出两圆的切线(In the file qiexian.m, enter the moire circle with the coordinates of two Moore circles, you can find the tangent of the two circle.)

用C++语言编写得职工信息管理系统(C language in the preparation of management information systems workers)

本程序可以用于轴系的扭转振动计算，根据测得的编码器信号序列，计算扭振角位移、角速度和角加速度(for torsional vibration calculation.)

说明：  采用涡格法估算低速飞机纵向气动特性，包括升力系数、阻力系数及俯仰力矩系数！(It's a great matlab program)

说明：  维纳滤波算法，可以实现对语音信号的降噪，效果还可以(Wiener filtering algorithm, it can achieve noise reduction on speech signals)

说明：  一款EA,操作能100%利润，1个月，外汇黄金操作，使用的就明白了，需要有外汇经验(An EA, operation can make 100% profit, one month, foreign exchange gold operation, the use of it is clear, need foreign exchange experience.)
