本文讨论了在背景磁通存在下，膜定域质量项对超环面轨道不动点的影响，其中在引入定域质量项之前，一般实现了多个最低和高能级Kaluza-Klein（KK）模.通过线性代数的知识，我们发现在每个KK能级上，当引入单个或多个膜定域质量项时，一个或多个简并KK模几乎不可避免地受到扰动。当紧致化的典型尺度远高于电弱尺度或TeV尺度时，我们应用这种机制来提升不需要的无质量或轻模式，这些模式容易出现在磁化轨道上的模型中。
We discuss effects of the brane-localized mass terms on the fixed points of the toroidal orbifold $T^2/Z_2$ under the presence of background magnetic fluxes, where multiple lowest and higher-level Kaluza-Klein (KK) modes are realized before introducing the localized masses in general. Through the knowledge of linear algebra, we find that, in each KK level, one of or more than one of the degenerate KK modes are almost inevitably perturbed, when single or multiple brane-localized mass terms are introduced. When the typical scale of the compactification is far above the electroweak scale or the TeV scale, we apply this mechanism for uplifting unwanted massless or light modes which are prone to appear in models on magnetized orbifolds.
