逐差法在球面曲率半径测量中的应用

The application of the graded datum subtraction handling method on measurement of the spherical curature

以牛顿环干涉实验测量平凸透镜的曲率半径为例,简述了处理数据的方法及其适用范围,并通过对两种数据处理方法的比较分析,得出用逐差法简便处理牛顿干涉实验的数据处理方法。

The graded datum subtraction handling method is generally used in physical experiment,however,it is very inconsistent and not normal. The measurement of plane convex;lens curvature radius by the Newon's rings is taken an example for illustrating briefly the a daptability and method of grded datum subtraction. Through comparing and analyzing the two analyzing the two kinds of datum handling methods, a simple and clear graded datum subtraction handling method is given.
