Abstract：
The relations among the space-parameters, average radii and root-mean-square radii of the different pion source density distributions are obtained with the power series expansion of the two-pion correlation functions at the small relative momentum. The results are in good agreement with the experimental measurement of the central collisions 1.8A GeV Ar+Pb. The average radius and root-mean-square radius of the above reaction are given. The values of k=2>/² for the different source density distributions are calculated.
