摘　　要：增加设计性和创新性实验的开设比例,不仅是大学物理实验课程改革需要,更是培养大学生创新能力的必然要求.本文设计、搭建了一种基于刚体转动惯量实验仪的液体粘滞系数测量实验装置,并做了测量举例.该装置不仅克服了手动秒表计时误差大的缺点,而且扩展了测量对象.本装置的设计、搭建可由学生利用实验室已有设备独立完成,适合开设设计性和创新性大学物理实验.To increase the proportion of the design and innovative experiment is not only the need of the reform of university physics experiment, but also the necessary requirement to cultivate the innovative ability of college students. In this paper, we design and set up an experimental device for measuring the liquid viscosity coefficient based on the rotating inertia experiment instrument, and made an example of measurement. The device not only avoids the manual stopwatch disadvantages of big errors, but also extend the measurement object. The design and construction of the device can be independently completed by students using laboratory equipment, which is suitable for setting up design experiment and innovative experiment.

关 键 词：设计性实验 创新性实验 转动惯量 粘滞系数
