用气垫转盘测转动惯量的数据处理及误差分析
Date processing and error analysis in measuring moment ofinertia with air-cushion turntable
【摘要】 利用最小二乘法对气垫转盘测转动惯量的数据进行一元线性回归 ,分析了实验误差来源 ,讨论了实验数据中出现摩擦力矩为负的原因 .
【Abstract】 Using the least squares method, the regression analysis of experiment date in measuring moment of inertia with air-cushion turntable is presented. The sources of error are analyzed, and the reasons of negative friction force moment in experiment are discussed.
