For the system such as NN,π〓π〓 in which there are not quark and antiquark with the same flavor, only t-channel OGEP is needed to consider; but for the system such as K〓 in which a quark and an antiquark may have the same flavor, the effect of q〓 annihilation must be taken into account.

The problem is how to consider the relativistic corrections to this potential. Adopting the assummation that the quark interaction is the sum of the usual one-gluon direct exchange and the mixture of linear scalar and vector potentials, we structure the relativistic corrections of order v2/c2to the Cornell potential, including the annihilation potential for the quark and antiquark of the same favors which plays the same role with the one-gluon direct exchange at short distances.

The final contribution of gluon-gluon fusion to total cross section can be as large as 5％ of that of quark annihilation because of the large luminosity of gluon in hadron collider.

虽然胶子聚合只有圈图阶的过程，但是由于强子对撞中胶子的高亮度，最终胶子对总过程截面的贡献也可以达到相应夸克贡献的5％。
