天平振动的研究

摘要

According to the torque balance equation ,the vibration of balance was discussed .By measuring the sensitivity of the balance and the period of the vibration ,the moment of inertia and the center of gravity were examined .The dependence of the sensitivity on weigh was analyzed and the un‐derstanding about balance w as deepened .%根据力矩平衡关系，讨论了天平的振动规律。通过测量天平的感度和振动周期，考查了天平的转动惯量、重心位置等参量，分析了天平感度随称量量的变化规律，加深了对天平的认识。
