| 摘 要： | 研究了在一维势场Ｖn＝λｃｏｓ（Ｑn＋ａｎｖ）（０＜ｖ＜１）中运动的电子状态，计算了本征能量和本征态的局域化指数。对Ｑ＝２π／３，系统的能带由三个子能带构成。当λ小于２时，每个子带中有两个迁移率边界。研究了扩展态、局域态以及迁移率边界随参数λ，ν，α的变化。

| Abstract: | In this paper, we study the states of electron in one-dimensional potential Ｖn＝λｃｏｓ（Ｑn＋ａｎｖ）（０＜ｖ＜１），calculate the eigenvalues and localized exponents. For Ｑ＝２π／３, the energy band is constructed by three subbands. There are two mobility edges in every subband provided that λ<2. We study the nature of the localized and extended eigenstates and mobility edge of this system as a function of λ，ν and α. |
