| 摘 要： | 在拉伸法测杨氏弹性模量实验中,许多学生对光杠杆和望远镜尺组的调节感到困难,比如不能成像或成像模糊等,其原因在于没有认识到本实验的关键技能是光路的正确调节方法,他们完成这一过程花费很多时间,且在很大程度上是“碰”出来的.本文定量介绍了正确调节光路的方法——正交定量调节法.

| Abstract: | Many students feel it difficult to adjust light lever and telescope rulers in Young's modulus experiment with tensile method, such as no image or blurting image may occur, etc. The reasons are as fol-lows: key skill in test for correct adjusting method is not comprehended and recognized; too much time spent during this process; and result in completing test is done "by chance" to a great extent. Correct method of adjusting light line ,perpendicular guantitative adjusting method is introduced in this paper. |
