摘　　要：将霍尔传感器应用于拉伸法测杨氏模量实验之中,不仅实现了力学量转化为电学量测量,提高了测量精度和测量速度,同时与光杠杆法测杨氏模量相比,还实现了动态测量——可以测出金属丝的瞬时微小位移量.这种实验方案也为普通物理实验增加了新的教学内容.In this paper,Hall sensor is applied in the measurement of Young Modulus by means of tensile method.It achieves the transference of mechanic values to electric values,improves the accuracy and velocity of measurement.Compared with the optical lever measurement of Young＇s modulus,it also achieves dynamic measurement which can measure the instantaneous Micro-Displacement.This experimental scheme will increase new teaching contents in the universal physical experiments.
