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
本文在重新劃分abbott - firestone曲線的基礎上引入了表面承載指數、核心區液體滯留指數和谷底液體滯留指數三個指標分別評價表面承載性能和儲油性能，同時通過試驗找到了這三個評價指數的變化規律，最後建立了它們和分形參數之間的關系，並發現尺度系數同樣可以用來評價表面的承載性能和儲油性能。 -
By using ec membrane material as column packing, double - distilled water as mobile phase, the retention times ( tr " ) are measured with suitable inorganic and organic compound as solutes. 3. complying with the retention times, the partition coefficient of the solute ( ka " ) and the ratio of the surface excess concentration of solute ( ) with the concentration of the parent fraction ( cab ) are calculated
利用物理改性的方法研製了乙基纖維素（ ethylcellulose ，簡稱ec ）膜材料，並將其作為高效液相色譜柱的固體填料，以高效液相色譜模擬反滲透實驗平衡條件，以水為流動相，選擇合適的無機物和有機物作為溶質，測定乙基纖維素對它們的相對保留時間及平衡分配常數k _ a 。
