Abstract：
With the assumption that the probability for n-charged particles production inhadron-hadron collision is Pn=xPn(1)+(1— x)Pn(2), whithin Pn(1)= andand proper choice of 1, 2, k and x, the true multiplicity distribution in full phase space can be described successfully at the centre fo mass energy GeV. Using the experimental data of non singe-diffractive collisions between proton and antiproton at centre of mass energies of 200 and 900GeV, the supposition had beenexamined and confirmed: it is very good to describe the facts. Had been discussed the theoretical bases of supposition.
