opencv 读取视频文件，可以控制帧率，但必须要有解码器-opencv read video files, you can control the frame rate, but you must have the decoder

运用Opencv，输入n帧图像，可以转换为一段avi格式的视频，可以控制视频的帧率。-Use Opencv, enter n frames, it can be converted to avi video format section, you can control the video frame rate.

用MATLAB实现的不合格品率P控制图的绘制,只要将数据导入(MATLAB nonconforming rate P control chart drawing, as long as the data import)
