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 effects of the relativistic corrections on the hyperfine splittings of quarkonium states are discussed , and a good fit to the available experimental data is obtained on heavy quarkonium mass spectra 采納庫侖勢源于單膠子直接交換,而線性禁閉源于標量和矢量的混合,同時考慮在短程區(qū)域與單膠子直接交換起同樣作用的同味正反夸克的湮滅,構(gòu)造了靜態(tài)夸克-反夸克勢到v ~ 2 c ~ 2級次的完全相對論修正,并擬合計算了重介子偶素的能譜,討論了相對論修正對重介子偶素能級分裂的作用。
