摘　　要：选择一座10000 m3的立式金属罐,使用围尺法和光电测距法进行基圆半径的测量,然后对两种方法的测量结果进行对比和不确定度分析。结果显示,两种方法的测量结果偏差小于其扩展不确定度,说明两种方法在立式金属罐的基圆半径测量结果上具有一致性。In this paper,a vertical measuring tank of 10000 m^(3) is selected,the radius of base circle is measured by the method of steel tapes and internal electro-optical distance-ranging method,then the measurement results of the two methods are compared and the uncertainty analysis is analyzed.The results showed that the deviation of the measurement results of the two different methods was less than that of the extended uncertainty,indicating that the two methods in the measurement of the radius of the base circle vertical measuring tank are consistent.
