摘要

实验基于改进后的新型焦利氏秤，利用光杠杆原理设计了运用胡克定律测量劲度系数的装置。该装置通过记录激光发生器发出光线反射在圆弧挡光板上移动的初末位置的距离，得出杠杆转动的角度，计算出测量弹簧的伸缩长度。克服了弹簧自重影响，减少了测量误差，使实验现象更加直观，增强了实验测量精确性。

Abstract:

The experiment is based on the improved Jolly’s scale，and a device for measuring stiffness coefficient using Hooke’s law is designed by using the principle of optical lever．The device obtains the rotation angle of the lever by recording the distance between the initial and final positions of light movement，calculates the extension length of the measured spring．The experiment overcomes the influence of the deadweight of the spring，reduces the measurement error，makes the experimental phenomenon more intuitive，and enhances the experimental measurement accuracy．

Key words: Hooke’s law lever principle spring stiffness coefficient Joly balance
