Abstract：
The influence from the transverse momentum conservation of the final particles to the scaling of factorial moments is studied in some detail.The experimental results on the “falling down”of factorial moments in azimuthal angle variable are explained successfully.Two new methods are proposed for calculating the factorial moments in order to eliminate the influence of momentum conservation partly and resume the inherent scaling of the fractal system.
