本文仔细地分析了当无序体系被嵌放在一个无限有序体系之中时,边界条件对体系本征态的影响。结果表明,在离边界距离大于局域长度的区域内,这种本征态能够重现无序体系的性质。这就提出了研究无序体系本征态的一种方便的方法。A careful analysis of the boundary effects on the eigenstates of a disordered system when it is embeded in an ordered system was carried out. It was found that the properties of the system in the region whose distance from the boundary is greater than the localization length of the system can be reproduced. This then suggests a convenient way to study the eigenstatea of disordered systems.
