晶粒的弗里特直径、平均截距、公称直径之间关系的研究

Investigation of the Relations among Frit Diameter, Average Intercept and Nominal Diameter of Crystall Grain

晶粒的平均截距和晶粒的弗里特直径及晶粒的公称直径是表示晶粒尺寸的三种方式，三者间存在着必然的联系。采用线性回归的方法对晶粒的平均截距、弗里特直径、公积直径进行回归分析．并从理论＿卜进行厂推导．认力品粒的平均截距，弗里特直径．公林直径的关系是高度显著性的线性关系、同时，证实了研究所得到的回归方程的正确性。

Average intercept, frit diameter and nominal diameter of crystal grain are the three expressing ways for crysatl grain size, which have certain relatiions among them. By means of linearregression method, aveage intercept, frit diameter and nominal diameter are analyzed and deduced theoretically. It is considered that there is clearly linear relation among the three parameters. Atthe same time, the regression equation obtained through investigation is proved out.
