The expressions of the affine fractal interpolation function and the locally explicit presentation of the vertical scaling factors are presented on the basis of fractal geometry. 在理論分析的基礎上給出了自仿射分形插值函數的表達形式和垂直比例因子的顯式表達形式。
The vertical scaling factor is an important parameter in the application of fractal interpolation method, which meanly decides the accuracy of the interpolation. 在分形插值方法中，垂直比例因子是影響插值精度的主要因素。
