摘　　要：利用自制的基于89C51微控单片机的胡克定律演示实验装置对传统的胡克定律演示实验进行了改进,改进后的实验装置用超声波精确测量弹簧的长度,在显示屏上能够直观地显示出实验温度和弹簧的长度,进而确定形变量及弹簧的弹性系数。与传统演示实验装置相比,该装置具有操作简单、直观性强、实验测量结果精确等优点,不仅可以作为教具用于课堂演示,而且可为弹簧系数的测量提供一种新的方法。The Hooke＇s law demonstration experiments based on the 89C51 Micro control single chip microcomputer are used to improve the traditional Hooke＇s law demonstration experiment. The improved experimental device with ultrasonic can accurately measure the length of the spring,and the experimental temperature and spring length are visually shown in the display screen. And then the amount of deformation and elastic coefficient of spring are determined. Compared with the traditional demonstration experiment device,the device has the advantages of simple operation,strong intuitive and accurate experimental results. It can not only be used as a teaching aid for classroom demonstration,but also provides a new method for spring coefficient measurement.
