摘要

According to the interplay model proposed in Ref. [1], an improved model, Collective-thermal Competition(Percolation) Model (CTCPM) is developed. The improvements are made by adding the momentum conservationinto the interplay of the thermal motion and the collective motion and limiting the emitting system to be finite.For a nuclear system at a thermal equilibrium, the momentum of the thermal motion distributes isotropically in x,y, z directions (z is the beam direction) and make no effect on the flow (Px) in average.
