摘要
本文讨论了用平行光管测量透镜焦距中的误差来源 ,并以测量数据说明了各误差来源对实验结果的影响程度 ,提出了相应的改正措施 ,取得了较好的效果。
The source of errors in measuring the focal length of the lens by parallel optical tuke is discussed.The influences of all kinds of errors on the experimental results are illustrated by the measurement data.The corresponding correct method is provicded and the acquired effect is quite good.
