Abstract：
In this paper,the theory of the minimum relative information entropy (MRIE) is applied to deduce the semi-inclusive single-particle rapidity distribution of final states of h-h produced in high energy collision.It is found that the cluster effect leads to centre deviate of the curve peaks of rapidity distribution,and the lower the multiplicity is,the more notable the cluster effect becomes.
