Abstract：
The anisotropy of the pion emission in the collisions of 1.8AGeV Ar+Pb is studied with the VUU model to obtain the information of the nuclear equation of state.We point out that the collective motion of pions in the final state has the final state has the characteristic similar to that of collective correlations of baryons,and the azimuthal anisotropy of pions is a sensitive parameter to the nuclear equation of state in the projectile rapidity region where the absorption of target spectator is weak.Collisions of 1.8AGeV Ar+Pb in the Bevalac streamer chamber are analyzed using the azimuthal correlation function for pions and the results favor the hard nuclear incompressibility.
