Abstract: With the power series expansion of the three-pion correlation function at small relative momentum, the relation between the three-pion correlation and root-mean-square radius of pion source is Obtained analytically. The relations between the space parameters of the pion source from 3π interferometry and 2π interferometry are also obtained when multi-pion correlation in three-pion events is or is not considered,The distortion of the two-pion coherence factor caused by the multi-pion correlation in three-pion events is calculated. And comparison is made between the results of 2π interferometry analyses at small relative momentum and the experimental measurements of the central relativistic heavy-ion collision 1.8A GeV Ar+Pb.
