In this article,the nonvanishing vacuum average value of two-point function of gluons <ΩA_(μ)^(a)(x)A_(v)^(b)(y)Ω>,which is related to the quantitative analyses of the nonperturbative effects in quantum chromodynamics(QCD)f is expanded in the''space-time interval τ=x-y in the JLorentz gauge.The first two coefficient values are estimated with the phenomenological values for the vacuum condensates<ΩG^(2)Ω> and <ΩψψΩ> through the QCD motion equations.The advantage of the expansion is that the series remains translationaily invarian£as compared with the expansion of〈ΩA_(μ)^(a)(x)A_(v)^(b)(y)Ω> in the fixed-point gauge.
