| 摘 要： | 焦距是透镜的重要参数之一,透镜成像的位置和性质与焦距有关。通过对位移法测凸透镜焦距的研究,得出在相同测量条件下D(物屏与像屏间距)的选取与测量误差的关系,总结出D值的大小对不确定度的影响规律。

| Abstract: | Focus length is one important parameter of lens, nd po on d properties imags are relative to focus length. Researching convex focus length by displacement method shows that in the same measuring condition, D （the space between object screen and image screen） is relative to measuring condition. The law of how the scale of D affects uncertainty is summarized. |
