| 摘 要： | 提出了3种圆柱体质量、质心和质偏测量方案，即4点式测量、轴径3点式测量和轴周3点式测量。针对其中的4点式测量方式又提出了2种测试方法，并比较了2种测试方法的误差；通过理论推导，对3种测试方案引起的质偏误差进行了优劣论证。

| Abstract: | Firstly,this paper put forward three testing scheme for cylinder's mass,centroid and centroidal deviation,which were 4-point measurement,axial 3-point measurement and radial 3-point measurement.Then,it put emphasis on 4-point measurement,and proposed two approaches based on 4-point measurement.Finally,the testing errors were analyzed theoretically. |
