Abstract: Comparing directly the correlation functions from different source density distributions, we propose that the average radius of the source obtained from two-pion interferometry analysis is quantity to describe the spatial size of the source. In the comparison the source spatial parameters from different correlation functions, the average radius of the source is a superior standard parameter to the root-mean-square radius suggested by Bartke and Kowalski, and is superior to the factor suggested by Goldhaber et al. A systematic study of the results from different heavy ion experiments demonstrates that a more reasonable result can be obtained by utilizing the average radius as a standard for comparison.
