We consider the four neutrino oscillation that accommodate the all neutrino oscillation data. We consider the range of the corresponding mixing parameters by the result of neutrino oscillation experiments. Implicaion of the neutrino oscillation search for the neutrino mass square difference and mixing are discussed. We determine the possible values of the effective majorana neutrino mass \(|<m>|=|{\sum }_{j}U_{ej}^{2}m_{j}|\) in the four neutrino scenario. In the four-neutrino scheme there is an upper bound on | < m > | of the normal mass order is 2.0074eV for α = 0^∘,β = 0^∘andγ = 0^∘. In the case of inverted mass order the upper bound on | < m > | is 2.0069eV for α = 0^∘,β = 0^∘andγ = 0^∘.

我们考虑容纳所有中微子振荡数据的四个中微子振荡。我们通过中微子振荡实验的结果来考虑相应的混合参数的范围。讨论了中微子振荡搜索对中微子质量平方差和混合的说明。我们确定了四种中微子场景中有效的中性微中子质量\（| <m> | = | {\ sum} _ {j} U_ {ej} ^ {2} m_ {j} | \）的可能值。在四中微子方案中，| |上有一个上限。< m > | 正常质量的顺序是2.0074eV为α = 0 ^∘，β = 0 ^∘一个Ñ d γ = 0 ^∘。在质量顺序倒置的情况下，|的上限 <m> | 是2.0069eV为α = 0 ^∘，β = 0 ^∘一个Ñ d γ = 0 ^∘。
