    中文摘要:
          介绍了一种基于Ｔｈｏｍｐｓｏｎ－Ｌａｍｐａｒｄ原理的交叉电导率标块测量系统。基准标块的电导率范围为１３％～１００％ＩＡＣＳ，其不确定度为０．０８％，对未知标块传递测量的不确定度为０．１４％＋０．１％ＩＡＣＳ。
    英文摘要:
          A measuring system for cross conductivity standard disc based on Thompson Lampard theory is introduced in this paper.The conductivity range of the standard disc is approximately from 13% IACS to 100% IACS,its uncertainty of measurement is 0.08%.The uncertainty of measurement of the unknown disc is about 0.14% 0.1% IACS.
