| Abstract: | The optimizing method of linear correlation coefficient is used for parameters N0,μand a of logarithmic normal distribution and a relative computation method is given. In the testdata of faitigue property is maximally emerged the linear relation in p-lg (N-N0) coordinatesystem. Practical examples show the fitting effect of straight lines is good. |
