【Abstract】 The δ-derivative and properties of continuous function are discuss ed in this paper.It shows that the δ-derivative is identical with the derivative of finite discrete function when the sample points are increased. It is also identical with the conventional derivative under the limit case.It po ssesses the properties similar to the conventional derivative.更多还原
