Abstract：
The anisotropy of azimuthal distribution for the final state particles in the center-of-mass coordinate systems where the z axis is rotated to various polar angles in the reaction plane is studied.A method to determine the flow angle is proposed. Studying the polar angle distributions for collisions of1.2AGeV Ar+KC,1.2AGeV Ne+NaF and 2.1AGeV Ne+NaF at the Bevalac streamer chamber in the coordinate systems with the z axis rotated to the now angles,we can estimate the fraction of the anisotropic emission particles to all the final state particles and the degree of concentration around the flow direction quantitatively.
