摘　　要：针对"用读数显微镜观测牛顿环"实验教学中学生提出的几个问题,用同一个牛顿环装置进行了多次实验测量并处理实验数据,结果表明,适当取高级数环、牛顿环装置接触中心圆面大小适当、光线方向正确,可有效提高凸面半径测量精度,并可有效减小随机误差。Based on the problems students raised during the experimental teaching of the observation of Newton＇s ring with a reading microscope, the paper discusses the repeated experiment measurement with the same Newton＇s ring device and the processing of experimental data. The results show that if the ring number is properly increased and the size of the circular area in the contact center of the device is appropriate in addition to the correct direction of the light, the accuracy of measurement results of convex radius can be effectively improved and the random deviation reduced.
