Abstract：
The effective two-meson-exchange potential with regard to the box diagram in the N-N interaction has been derived by virtue of the one-gluon-exchange quark-antiquark pair creation model. The result shows that the general feature of this effective potential agrees with that of the phenomenological σ-meson exchange potential in the coordinate space.
