分形学与精密机加工表面精度评定

Fractus and Surface Precision Measurement of Precision Opticalmachinery Processing

分形学是波兰科学家B．Mandelbrot在六十年代创立的一门新兴学科，它主要研究传统的欧氏几何不能解决的复杂和无规则的自然景物．目前，分形学在理论方面已经有了一定的发展，但在实际应用方面还处于起步阶段．把分形学应用到现实生活中大量存在的机械加工表面的形貌分析中去，这是一项有重大意义的工作．

Fractus is a new subject established by a Poland scientistnamed B. Mandelbrot in 1960s, its main study object is the complex andirregular natural scenery that the traditional Euclidean geometry cannotsolve. At present,fractus has its advancement in theory,while thepractical application is still at the primary stage. Therefore it is asignificant work to utter fractus into the surface shape analysis of machinery processing existed in our dally life
