Abstract：
The influence of the meson radial structure on the meson-baryon vertex functions is studied. A mixing wave function of 0S state and 1S state is used to compare with the 0S structure calculation. The result shows that the mixing structure is important for improving the coupling constant of NNπ vertex.
