Abstract：
The even and odd multiplicity distributions for hadron-hadron collision in different rapidity windows are calculated,starting from a simple picture for charge correlation with nonzero correlation length.The coincidence and separation of these distributions are explained.The calculated window-and energy-dependence of normalized moments recover the behaviour found in experiments.A new definition for normalized moments is propossed,especially suitable for narrow rapidity windows.
