扩程电阻的误差分析

Error Analysis of Extending Resistance

本文利用误差理论导出了扩程电阻的误差表达式，并对扩程电阻的误差与各物理量的关系进行了分析，寻找出了规律。对误差的来源以及大小从理论上得到了明确的解释。

In this paper, an error expression of extending resistance is derived ty using theerror theory, and the relation tetween the error of extending resistance and any physical quantityis analysed to find out varying rule of the error. The source and magnitude of the error is reasonably explained by the theory.
