摘要
以现代化的实验手段改造传统实验,给予学生丰富的综合性实验技能训练,是各类实验课程改革的一项重要任务。作为信号分析和基础物理实验相结合的一个范例,引入感测技术和计算机技术,特别是频谱分析法改造了单摆测量重力加速度的实验,并完成了传统单摆实验无法完成的阻尼系数测量,既丰富了实验内容,又扩展了理工科学生应用现代化实验手段的能力。
An important task of reforming experiment courses is to reconstruct traditional experiments by modern technique and to give students more practical training.As a good example of combining signal analyses with basic physics experiments,using the sensor technique and computer technique,especially the method of spectrum analyses,the simple pendulum experiment of measuring gravity acceleration is reformed in the paper.Also damping coefficient of pendulum has been measured in the experiment,which can not be conducted according to the traditional method.The proposal in the paper enriches pendulum experiment and expands experimental skills of university students.
