Abstract：
Proton-proton collisions at s=22GeV and 200GeV have been simulated by PYTHIA model. The fixed-to-arbitrary and neighboring bin correlation patterns at these two colliding energies are investigated. It has been found that the neighboring bin correlations are the strongest at the central rapidity region and become weaker and weaker toward the two side rapidity regions; while the fixed-to-arbitrary bin correlations vary from one fixed bin to another.
