Intermittency and Phase Transition

On the basis of a lattice gas model and the convolution formula with cell construction scheme, we demonstrate that intermittency in the rapidity-space with respect to the scaled moments comes from a phase transition between ordered phase and disordered phase. It is pointed out that as concerns the power-law behavior of the moments the critical exponent depends on the size of rapidity interval in the case of the system which is not enough near to the critical point.
