摘要
随着近代物理学的发展 ,应用量子效应来建立基本单位的新型基准 ,可以大大提高基准的准确度 .介绍量子霍尔效应及交流约瑟夫森效应在电阻基准和电压自然基准方面的应用 。
Degree of accuracy of base unit was raised well by using quantized effect to establish new standard of based unit with the development of modern times physics. Quantized Hall effect and alternating Josephsen effect as well as their applications in resistance constand based and voltage constand based are introduced. Research of constand based has been becoming main research direction of metrology.
