【摘要】 黄金比是自然界物质最常见的自相似比例；全息生物学揭示了生物界普遍存在的全息现象即分形现象；分形从数学方面描述了自然界物质的自相似结构。黄金分割律、全息生物学和分形几何三者从不同角度揭示了自然界的自相似性，凡是自然界客观存在的或经过抽象而得到的具有自相似性的几何对象，均称为分形。更多还原

【Abstract】 Golden proportion is most common self-similarity proportion of of objects in nature. ECIWO biology discvers commonly existed holographic phenomenon-fractal phenom-enon. From the view point of mathematics,fractal has described self-similarty structure of ob-jects in nature.Golden sectional law, ECIWO biology and fractal geometry have, from the dif-ferent view points,exposed self-similarity of nature. All geometric subjects with self-similarity are called fractal that either have already existed in nature or have been abstracted from nature.更多还原
