三线摆法与扭摆法测量物体转动惯量之比较

Comparison of Measuring Moment of Inertia by Tri-linear Pendulum and Torsional Pendulum

教学比较研究是教学研究的重要方法,是符合新时期高等教育教学创新发展要求的重要教学实践。实验教学比较研究包含了教学理念、体系、内容和方法等多个方面的教学研究活动。通过选取刚体转动惯量这一重要的物理量,从实验原理、实验内容、实验操作和数据处理等多方面,详细比较了三线摆法和扭摆法这两种常见测量方法的异同点。这样的教学比较对于提高教育教学质量,提升学生创新能力,有着重要的实践意义,值得推广到物理实验课程的其他实验中去。

Teaching comparative research is an important method of teaching research and an important teaching practice in line with the requirements of teaching innovation and development in higher education in the new era.The comparative research of experimental teaching includes teaching research activities from many aspects,such as teaching idea,system,content and method.By selecting the moment of inertia of rigid body,an important physical quantity,the similarities and differences between the tri-linear pendulum method and the torsional pendulum method are compared in detail,from the experimental principle,experimental content,experimental operation and data processing.This kind of teaching comparison has important practical significance for improving the quality of education and teaching and enhancing students’innovation ability.It is worth extending to other experiments of physics experiment course.
