英文摘要	We have carefully examined, in both analytical and numerical ways, how small the terrestrial matter effects can be in a given medium-baseline reactor antineutrino oscillation experiment like JUNO or RENO-50. Taking the forthcoming JUNO experiment as an example, we show that the inclusion of terrestrial matter effects may reduce the sensitivity of the neutrino mass ordering measurement by Delta chi(2)(MO)similar or equal to 0.6, and a neglect of such effects may shift the best-fit values of the flavor mixing angle theta(12) and the neutrino mass-squared difference Delta(21) by about 1 sigma to 2 sigma in the future data analysis. In addition, a preliminary estimate indicates that a 2 sigma sensitivity of establishing the terrestrial matter effects can be achieved for about 10 years of data taking at JUNO with the help of a suitable near detector implementation.
