英文摘要: We try to reconcile the tension between the local 2.4 % determination of Hubble constant and its global determination by Planck CMB data and BAO data through modeling the dark energy variously. We find that the chi-square is significantly reduced by Delta chi(2)(all) = -6.76 in the redshiftbinned dark energy model where the 68 % limits of the equation of state of dark energy read w(0 <= z <= 0.1) = -1.958(-0.508)(+0.509), w(0.1 < z <= 1.5) = -1.006(-0.082)(+0.092), and here w(z > 1.5) is fixed to -1.
