Abstract：
In this paper we study a modified skyrme model with m_π≠0 and compute the static properties of nucleons in this model.The results show that most of theoretical values have been improved,especially 2>^1/2=0.56fm is two times as one from the original Skyrme model and it is close to experimental value.
