Abstract：
According to the perturbative QCD method,we have calculated the P_⊥ distributive cross sections,the Y distributive cross sections of the large P jets and the final state meson productivities in 800GeV/c Proton-Nucleus (Be,C,Al,Cu and Pb) collisions.The A dependence of the cross section at a given P_⊥ was discussed by the EMC effect. The dσ/dP_⊥ differential cross sections vs .P_⊥ for various PA collisions are consistent with the new data.
