Abstract：
By means of the quark-antiquark pair creation model via one-gluon exchange, the effective ion among quarks,which is equivalent to the meson exchange intervening between two hadrons, is discussed. It is shown that this process includes interactions not only between two quarks, but also among three quarks. Obviously, such effective interaction is more general than one gluon exchange potential (OGEP).
