Description: 分维,是分形的定量表征和基本参数，通常用分数或带小数点的数表示。
长期以来人们习惯于将点定义为零维,直线为一维,平面为二维,空间为三维,爱因斯坦在相对论中引入时间维,就形成四维时空。对某一问题给予多方面的考虑,可建立高维空间,但都是整数维。
-Fractal dimension is a fractal of the quantitative characterization and basic parameters, usually scores or take a few decimal points, said. It has long been accustomed to the definition of zero-dimensional point, a straight line for the one-dimensional, flat for the two-dimensional, space for three-dimensional, Einstein
