Abstract：
The effect of the absorption of pion mesons in relativistic asymmetrical heavy-ion collisions on pion-source parameter is studied with two-pion interferometry at small relative momentum. The relations between the source parameters are obtained when the pion absorption is considered or not. Comparison with the experimental measurements of relativistic asymmetrical central heavy-ion collisions 1.8A GeV Ar+Pb is made.
