Based on re - classification of abbott - firestone curve into three zones , surface bearing index , core fluid retention index and valley fluid retention index were introduced to evaluate the bearing capability and lubricant retention property of a machined surface . the changing tendency of these three indexes was also made clear through experiments , and the relations between them and fractal parameters were built up . at last , it was found that the coefficient c is also suitable to evaluate the bearing capability and fluid retention property of a machined surface
本文在重新划分abbott - firestone曲线的基础上引入了表面承载指数、核心区液体滞留指数和谷底液体滞留指数三个指标分别评价表面承载性能和储油性能，同时通过试验找到了这三个评价指数的变化规律，最后建立了它们和分形参数之间的关系，并发现尺度系数同样可以用来评价表面的承载性能和储油性能。
