摘　　要：本文计算了以U_c(r)=1/2×kr^2+λ_1r^4+λ_2r^6+C为囚禁势的重夸克偶素能谱的相对论修正。计算结果表明,考虑相对论修正后,大多数能级比未考虑相对论修正时与实验值符合得更好。Relativistic correction of heavy quarkonium spectra were analysed with a phenomenological confinement potenlial of the form U_c(r)=1/2kr^2+λ_1r^4+λ_2r^6+C. The results showed that, if we included relativistic correction, the majority theoretical calculated results were in better agreement with experimental values than nonrelativistic calculated results.
