虽然人们可以制作一些形状规则的几何体,但自然界中大量存在的却是不规则的现象或物体,科学家早已发现,用规则的几何图形作数学模型去描述它们,难免歪曲其真实特性,是不精确的。分形(Fractal)则是一种新的几何概念,用以描述有粗糙复杂边界的图形的空间情况,或空间充填能力。分形理论是由法国数学家兼计算机专家B·曼德尔布罗特(B·Mandelbrot)于1975年首先提出来的,十几年来,分形几何迅速发展为一门新兴的数学分支,并已成为一种研究和处理一些自然和工程不规则图形的有力工具。
Although people can make geometric shapes with regular shapes, many phenomena in the natural world are irregular phenomena or objects. Scientists have already discovered that using regular geometrical figures as mathematical models to describe them will inevitably distort their true characteristics and be inaccurate. of. Fractal is a new geometric concept used to describe the spatial situation or space filling ability of graphics with rough and complex boundaries. The fractal theory was first proposed by B. Mandelbrot, a French mathematician and computer expert, in 1975. For more than a decade, fractal geometry has rapidly developed into an emerging branch of mathematics and has become a A powerful tool for researching and processing some natural and engineering irregular patterns.
