我们报道了利用Super-Kamiokande I大气中微子数据进行的三味振荡分析的结果，假定有一个质量尺度优势({Delta}m{sub12}{sup 2}=0)。无论是在多GeV{Nu}{sube}富样品中，还是在{Nu}{Sub{Mu}}富GeV样品中，中微子在地球内部传播{theta}{sub13}{ne}0时，由于物质效应而发生的通量没有显著变化。正态和倒转质量等级假说都得到了检验，两者都与观测结果一致。只使用Super-Kamiokande数据，得到了二维90%的置信度允许区域：对于正常质量等级，混合角被限制在sin{sup 2}{theta}{sub13}；0.14和0.37；lt；sin{sup 2}{theta}{sub23}&lt；0.65。对于质量等级倒置的情况，得到了较弱的约束sin{sup 2}{theta}{sub13}&lt；0.27和0.37&lt；sin{sup 2}{theta}{sub23}&lt；0.69。
We report on the results of a three-flavor oscillation analysis using Super-Kamiokande I atmospheric neutrino data, with the assumption of one mass scale dominance ({delta}m{sub 12}{sup 2}=0). No significant flux change due to matter effect, which occurs when neutrinos propagate inside the Earth for {theta}{sub 13}{ne}0, has been seen either in a multi-GeV {nu}{sub e}-rich sample or in a {nu}{sub {mu}}-rich sample. Both normal and inverted mass hierarchy hypotheses are tested and both are consistent with observation. Using Super-Kamiokande data only, 2-dimensional 90% confidence allowed regions are obtained: mixing angles are constrained to sin{sup 2}{theta}{sub 13}<0.14 and 0.37<sin{sup 2}{theta}{sub 23}<0.65 for the normal mass hierarchy. Weaker constraints, sin{sup 2}{theta}{sub 13}<0.27 and 0.37<sin{sup 2}{theta}{sub 23}<0.69, are obtained for the inverted mass hierarchy case.
