牛顿环法测平凸透镜曲率半径的数据处理

Data Processing for Measuring Radius of Convex Lens With a Method of Newton's Ring

牛顿环法测平凸透镜曲率半征时，直接测量量为牛顿环的直径，而这一直径的测量为不等精度测量，本文采用了一种特殊的方法，使测量直径时的不确定度传播至变量替换后的一无线性方程中的y时，使y的不确定度与X无关．即y的测量（间接测量）为等精度测量．这样使这一测量的数据处理变为等精度测量的数据处理．

Radius of Newton' s ring is directly measured when the radius of convexlens is measured with the method of Newton's ring, This paper adopts a special method. Inthe method when uncertainty of the radius of Newton's ring is transferred to y of linear equation with one unknown in which the variable quantity is replaced the uncertainty of y hasnothing to do with x. In another words, measuring y is equally-precision by the method. Thedata processing of the measuring results is changed to one of equally-precision measuring.
