Abstract：
After carefully analysing the scatter plot of pt vs.N of hadron-hadron collisions at s=540GeV,we point out that the appearence of large average transverse momentum per event pt and large multiplicity N is a new experimental evidence of existing hard component at the collision.The Monte Carlo simulation for one(soft) and two(both hard and soft) component model demonstrates qualitatively correct ness of this arguement.
