摘要
分形为研究工程表面轮廓开辟一条新的有效途径.工程表面轮廓只有在无标度区间内才具有分形特征,而无标度区间的确定能确保应用分形几何解决实际问题的正确性.讨论3种无标度区间的计算方法,并对这些方法进行比较、分析和评价.最后,应用逐渐逼近法,研究花岗石磨抛表面的分形无标度区.
Fractal opens up a new way for investigating engineering surfaces. Engineering surfaces have the fractal charactcristics only in the non-scale range. To determine the non-scale range can make sure to obtain the accurate results of the fractal dimension of engineering surfaces. Three kinds of the methods currently used for computing the non-scale range are discussed, compared and analyzed. Finally, method of successive approximation is used for study of non-scale range of engineering surfaces.
