一个现实的中长基线中微子实验可能会受到陆地物质效应的影响，这些效应可能会污染v(α)-gt；v(β)和v(Beta)-gt；v(α)振荡之间的真正违反T的不对称性。借助于物质中轻子质量矩阵的换位子，我们证明，只要中微子束能量E和基线长度L满足条件10(-7)(L/公里)(2)(GeV/E)v(β)和(V)在物质中的巴(α)->；(V)在物质中的巴(β)振荡，这种污染在各种实验中是可以忽略的。
A realistic medium-or long-baseline neutrino experiment may suffer from terrestrial matter effects which are likely to contaminate the genuine T-violating asymmetry between v(alpha) -> v(beta) and v(beta) -> v(alpha) oscillations. With the help of the commutators of lepton mass matrices in matter, we show that this kind of contamination is negligible for a variety of experiments provided the neutrino beam energy E and the baseline length L satisfy the condition 10(-7) (L/km)(2) (GeV/E) v(beta) and (v) over bar (alpha) -> (v) over bar (beta) oscillations in matter.
