本文研究了均匀磁场和周期衬底势U作用下二维电子气的霍尔电导。久保公式是以一种形式写的，当费米能位于能隙中时，它使量子化变得明显。对于大的和小的U ε ω c，已经获得了霍尔电导的显式表达式。
The Hall conductance of a two-dimensional electron gas has been studied in a uniform magnetic field and a periodic substrate potential U. The Kubo formula is written in a form that makes apparent the quantization when the Fermi energy lies in a gap. Explicit expressions have been obtained for the Hall conductance for both large and small U ℏ ω c.
