整数量子霍耳效应和电阻标准

Interger Qnantum Hall effect and resistance standard

本文介绍新的电阻标准，阐述量子霍尔效应的基本原理，运用朗道能级和局域态等慨念解释二维电子气体在低温和强磁场下的行为．

In the paper the new resistance sfandard is reviewed.The fundamental principle of Integer Qunatunl Hall Effect is discussed using the concepts of Landau energy levels and Localized states, the emphasis on the property of the two-dimensional electron gas under low temperatures and strong external magnefic fields.
