Abstract：
We derived a new formula for the mass plitting of N and Δ on the basis of the Skyrme model with the consideration of the soft pion effect. The results showed that the soft-pion fluctuation cannot be ignored in the evaluation of the ground state energy of some hadron like nuleon etc. The results obtained are better than that of Adkins et al. (1984).
