差值法与比值法的误差修正效果比较研究及应用

差值法与比值法对不同测量系统的误差修正效果不一样。本文将两种方法的比较用一个比值来描述，并用推得的公式进行量化表示。在进一步的应用研究中，理论分析与实验数据相互印证，同时得到许多有益的结论，有助于全面掌握测量系统的误差来源，从而灵活选择各种修正方法以获得更加准确的测量结果。

Application and the Comparison of the Difference Method and the Ratio Method in the Correction of the Error

In different measurement systems, the error correction effect is also different for the difference method and the ratio method. The comparison between the two methods is described with a rate, and the rate is quantitatively expressed by the deduced equation in this paper. In the farther study of application, the theoretical analysis and the experimental data are verified with each other, and some instructive conclusions are obtained, which are helpful to be aware of the error source across-the-aboard, and to adaptively choose various correction methods for obtaining the more accurate measurement results.
