摘　　要：对测圆盘转动惯量实验进行改进,避免了耗材、不安全、仪器易损坏等问题;在原理上消除了摩擦阻力矩的影响,提高了实验精度;对实验室现有资源进行改造,提高了实验仪器的利用率.The improved instrument of rotational inertia of disk avoids such problems as the costexpensive, insecure and easy damageable. This instrument greatly eliminates the impact of the friction moments, increases the accuracy of experiment, reuses waste parts and has increased the utilization of the experimental equipment.
