Abstract：
We Construct a pion cloud MIT-bag model with chiral symmetry. The pion cloud outside the bag is a classical spherica field. The calculated hadron mass spectra are comparable with the experimental data. The decay width of Δ⁺⁺(1236) calculated in this model is Γ_Δ=115.8 MeV, which is very close to the experimental value. We also calculate the phase shift of P₃₃ resonance. The resultin curve fits the experimental data exceedly well.
