说明：  slipping model control (vc)

说明：  该模型设计的是AC-DC换流器，能够将交流电转换为直流电压，用于整流控制(AC-DC converter)

多径理解2,理解多径对信号的影响 ,(two multi-path understanding, understanding of the multi-path signals and understanding of the multi-path signals,)

对图像进行逐点计算，并且取最大值和最小值的差值作为该点新的灰度值。 在区别边缘点和非边缘点时，首先确定一个阈值T，若图像中像素点的新 值大于该门限值，则可以初步确定为边缘点，小于T的新值被判断为非边缘点.(Image point by point basis, and taking the maximum and minimum points of difference as the new gray value. Edge in the difference between point and non-edge point, first determine a threshold T, if the image of the new pixel value is greater than the threshold, you can initially identified as the edge point, the new value is less than T have been judged as non-edge point.)
