声音信号处理，分析软件，能给出各种声源，能进行声音信号采集。-voice signal processing, and analysis software can provide a variety of sound sources, a voice signal can be collected.

通过输入任意三点空间坐标自动判断三点是否在一条直线上，若不在则求三点外接圆的圆心位置和半径，计算精度可调节。解决了“知三点求圆心半径”程序对于某些点无法计算的缺陷。-Calculated the radium of circle on the base of three point space position.

自动识别气泡边缘，以及计算单个气泡的半径的带下，可以大批量处理多个连续的奇葩图像，得到气泡半径随时间变化的曲线图-Automatic Identification bubble edge, vaginal discharge and calculating single bubble radius, can handle large quantities of a plurality of consecutive wonderful i
