gradation equation.A reasonable gradation equation should have the ability to describe sigmoidal curves and hyperbolic curves. Additionally, the gradation equation should satisfy that when d=dmax, P... gradation equation can only reflect the hyperbolic curve, as can be seen in Figure 2. That is, the fractal gradation equation lacks the ability to describe the sigmoidal curve. If this deficiency can......
