| 摘 要： | 根据干涉场中的光强分布规律，推导出牛顿环的光强分布表达式，运用误差分析方法，得出干涉环的宽度对曲主半径Ｒ的测量误差影响，必须用加权平均值及其标准偏差处理实验数据等结论，同时导出了两个新的推论。

| Abstract: | According to the law of light intensity distribution in the interferencefield, an expression for the distribution of light intensity in the Newton's rings isderived. By use of the error analysis, some conclusions are obtained. The spacingbetween two fringes has no effect upon the error of measurement of the curvatureradius R,and for processing experimental data the weighted mean and its standarddeviations must be used, at the same time, two new deductions are obtained. |

| Keywords: | Newton's rings error of measurement weighted mean standard deviation |
