英文摘要	We present an anisotropic analysis of the baryonic acoustic oscillation (BAO) scale in the twelfth and final data release of the Baryonic Oscillation Spectroscopic Survey (BOSS). We independently analyse the LOWZ and CMASS galaxy samples: the LOWZ sample contains contains 361 762 galaxies with an effective redshift of zLOWZ=0.32; the CMASS sample consists of 777 202 galaxies with an effective redshift of zCMASS=0.57. We extract the BAO peak position from the monopole power spectrum moment, a0, and from the 2 moment, a2, where is the cosine of the angle to the line-of-sight. The 2-moment provides equivalent information to that available in the quadrupole but is simpler to analyse. After applying a reconstruction algorithm to reduce the BAO suppression by bulk motions, we measure the BAO peak position in the monopole and 2-moment, which are related to radial and angular shifts in scale. We report H(zLOWZ)rs(zd)=(11.60 +/- 0.60) 103kms-1 and DA(zLOWZ)/rs(zd)=6.66 +/- 0.16 with a cross-correlation coefficient of rHDA=0.41, for the LOWZ sample; and H(zCMASS)rs(zd)=(14.56 +/- 0.37) 103kms-1 and DA(zCMASS)/rs(zd)=9.42 +/- 0.13 with a cross-correlation coefficient of rHDA=0.47, for the CMASS sample. We combine these results with the measurements of the BAO peak position in the monopole and quadrupole correlation function of the same dataset \citep[][companion paper]{Cuestaetal2015} and report the consensus values: H(zLOWZ)rs(zd)=(11.63 +/- 0.69) 103kms-1 and DA(zLOWZ)/rs(zd)=6.67 +/- 0.15 with rHDA=0.35 for the LOWZ sample; H(zCMASS)rs(zd)=(14.67 +/- 0.42) 103kms-1 and DA(zCMASS)/rs(zd)=9.47 +/- 0.12 with rHDA=0.52 for the CMASS sample.
