摘要
采用计算机模拟的方法研究了N(ε)∝ε^(-D)在测量、计算材料分维时,测量码尺的选择对所得到的分维D的影响,以及实际的分形体由于存在不同的类型和包含不同的自相似层次对实际测量分维的作用。
Using computer simulation method, we have studied that the kinds, levels of the actual fractals and measurement yardsticks influence on the measurement and calculation of the fractal dimension of the actual fractals, and found that the realistic fractal dimension is easily obtained in the measurement only when the numbers of the kinds and levels of the actual fractals are much larger. In addition, the selected range of the yardstick is suggested to be determined by the numbers of the levels of actual fractals.
