英文摘要	A measurement of electron antineutrino oscillation by the daya bay reactor neutrino experiment is described in detail. six 2.9-gwth nuclear power reactors of the daya bay and ling ao nuclear power facilities served as intense sources of nu((e) over bar)'s. comparison of the (v) over bare rate and energy spectrum measured by antineutrino detectors far from the nuclear reactors (similar to 1500-1950 m) relative to detectors near the reactors (similar to 350-600 m) allowed a precise measurement of (v) over bar (e) disappearance. more than 2.5 million (v) over bar (e) inverse beta-decay interactions were observed, based on the combination of 217 days of operation of six antineutrino detectors (december, 2011-july, 2012) with a subsequent 1013 days using the complete configuration of eight detectors (october, 2012-july, 2015). the (v) over bar (e) rate observed at the far detectors relative to the near detectors showed a significant deficit, r = 0.949 +/- 0.002(stat) +/- 0.002(syst). the energy dependence of (v) over bar (e) disappearance showed the distinct variation predicted by neutrino oscillation. analysis using an approximation for the three-flavor oscillation probability yielded the flavor-mixing angle sin(2)2 theta(13) = 0.0841 +/- 0.0027(stat) +/- 0.0019(syst) and the effective neutrino mass-squared difference of broken vertical bar delta m(ee)(2)vertical bar = (2.50 +/- 0.06(stat) +/- 0.06(syst)) x 10(-3) ev(2). analysis using the exact three-flavor probability found delta m(32)(2) = (2.45 +/- 0.06(stat) +/- 0.06d(syst)) x 10(-3) ev(2) assuming the normal neutrino mass hierarchy and delta m(32)(2) = (-2.56 +/- 0.06(stat) +/- 0.06(syst)) x 10(-3) ev(2) for the inverted hierarchy.
