巴黎综合技术高等学校压缩物理学实验室与法国Colas道路建设公司最近利用分形数学模型 ,研制成功一种高性能降噪墙。分形数学是描述自然结构模型的一门科学 ,自然界的许多现象 ,如菜花、肺部支气管和海岸岩石、沙滩等貌似不规则的形态 ,其实也是由某种不同尺度的形态复制而成的 Paris Institute of Compression Physics Laboratory and Colas Road Construction Co France recently using fractal mathematical model, the successful development of a high-performance noise reduction wall. Fractal mathematics is a science and natural phenomenon that describes the natural structure model. Many phenomena in nature, such as cauliflower, lung bronchus and coastal rocks, beaches and other seemingly irregular shapes are in fact copied from morphological forms of different scales
