说明：  语音信号的matlab处理程序,很多种，大家验证一下(Matlab voice signal processing, are many, we test)

This example demonstrates how to use the backend service in Google-App-Engine. 1. Change name of application in app.yml and firstmodule.yaml to the name of you application 2. Upload the files 3. Open the main page

正方形ABCD的4个顶点各有1人.在某一时刻,4人同时出发以匀速v=10m/s按顺时针方向追逐下一人,如果他们始终保持对准目标,则最终按螺旋状曲线于中心点O.试求出这种情况下每个人的行进轨迹(Four vertices of square ABCD each one. At a time, 4 people starting at a uniform v = 10m/s in a clockwise direction chasing the next person, if they remain at the target, then press the spiral curve in the final Find the center point O. This road track of each person)
