摘要
通过具体实验过程发现FD-TX-HY-Ⅰ霍尔位置传感器法测定固体杨氏模量实验的缺陷所在,通过对铜刀口的适当改进以及增加发光二极管进行视场照明,有效克服了实验误差,促进了学生的实验热情。
The defects in experiment of measuring Young's modulus by FD-TX-HY-ⅠHall position sensor are found.By the improvement of copper knife-edge and the increase in light-emitting diode as the field illuminators,the experimental error is effectively overcame and students are stimulated to have enthusiasm for college physics experiment.
