摘要：
Based on the extended Ginzburg-Landau model, it is shown that the dependences of the scaled factorial moments In F-q on phase space intervals are different for first- and second-order QGP phase transitions. When In F-q are fitted to polynomials of X = delta(1/3), the relative sign between the fitted coefficients can be used to judge the order of phase transitions.
