A renovated Manna model is studied by computer simulation. The dynamic behavior of the system is changed evidently with the density of particle number.There is a critical particle number density (PND)ρc≈0.684… and critical exp onent α=0.452±0.02 at this density. Self-organized critical phenomena occur only at certain ranges of PND.
