英文摘要	We report the constraints of H-0 obtained from Wilkinson Microwave Anisotropy Probe (WMAP) 9-year data combined with the latest baryonic acoustic oscillations (BAO) measurements. We use the BAO measurements from 6dF Galaxy Survey (6dFGS), the SDSS DR7 main galaxies sample (MGS), the BOSS DR12 galaxies, and the eBOSS DR14 quasars. Adding the recent BAO measurements to the cosmic microwave background (CMB) data from WMAP, we constrain cosmological parameters Omega(m) = 0.298 +/- 0.005, H-0 = 68.36(-0.52)(+0.53) km . s(-1). Mpc(-1), sigma(8) = 0.8170(-0.0175)(+0.0159) in a spatially flat Lambda cold dark matter (Lambda CDM) model, and Omega(m) = 0.302 +/- 0.008, H-0 = 67.63 +/- 1.30 km . s(-1) . Mpc(-1), sigma(8) = 0.7988(-0.0338)(+)(0.0345)( )in a spatially flat omega CDM model, respectively. Our measured H-0 results prefer a value lower than 70 km . s(-1). Mpc(-1), consistent with the recent data on CMB constraints from Planck (2018), but in 3.1 and 3.5 sigma tension with local measurements of SH0ES (2018) in Lambda CDM and omega CDM framework, respectively. Our results indicate that there is a systematic tension on the Hubble constant between SHOES and the combination of CMB and BAO datasets.
