Abstract：
The one boson exchange nuclear force is applied to the discussion of the nucleon-△ interaction. The coupling constant is determined by the straton model. Assuming that the wave function is unaltered by the presence of △, we are able to obtain the average field of the isobar in the nuclei approximately. The qualitative feature obtained is that the average field of △ is shallower then that of nueleon by an amount of～15 MeV.
