Abstract：
The structure of the nucleon-meson coupling is discussed on the basis of QCDperturbation theory. The transition amplitude for the Nucleon-Nucleon (Baryon) +Meson is obtained in the spherical cavity approximation of MIT bag model. From theanalysis of these amplitude (probability) it shows that the exchange of heavy mesonsof the first excited state (B, δ, A₁,...) and the 2π exchange (intermediate states N^*.△^*) are important in the zero range N-N interaction. However, the one-pion and onep、ω. etc do not appear.
