摘要：

To obtain a better approximation of the statistical behavior of ̂m, it is proposed that the variable 1n(̂m/m), named X, follows a three parameter Weibull distribution. The mean values, M and Mx and the standard deviations, S and Sx, of the variables ̂m/m and X, are calculated and fitted to the sample size, n, with four-parameter functions.
