Analytical expressions for the scaled factorial moments of multiplicity difference distribution are obtained for small bin size $δ$ with mean multiplicity in the bin ${\bar s}\le 1.0$ within Ginzburg-Landau description. The scaling behaviors between the moments are still valid, though they behave completely different from the so-called intermittency patterns. A universal exponent $γ=1.4066$ is given to describe the dynamical fluctuations in the phase transition in small $δ$ limit.4 pages, RevTeX, 3 figures in EPS formatHigh Energy Physics - Phenomenologytext
