摘　　要：介绍了下卧式径向偏心仪的结构原理及其灵敏度的调整方法,说明了构件径向偏心位置的测定方法及误差分析。利用这种偏心仪测量某些轴对称构件的质心位置,其测量不确定度优于1%。The paper describes the principle of the horizontal radial off-center instrument and adjnstment method of its sensitivity It explains measurement method and error analysis.When the center of mass for some axial symmetric components are measured by the instrument, its uncentainty is less than 1%.

关 键 词：偏心仪 质心测量 测量方法 误差分析
