摘　　要：球形罐计量检定规程的全站仪测量法中指出:"根据全站仪测量的环境温度和罐壁温度,把测得的赤道外半径和竖向外半径修正到标准温度20℃时的外半径"。但没有提出具体的修正公式,本文将推导出温度对球形罐外半径测量影响的修正公式。用此修正公式修正后将大大提高球形罐的计量准确度。It is stated briefly in the total station measuring method of spherical tank metrological verification procedures that ＂amend the measured equatorial outer radius and vertical outer radius to that when the temperature is 20℃ according to the environment temperature and tank shell temperature.＂ But the specific modifier formulas is not given. This paper will deduce the modifier formulas of the influence of temperature on spherical tank radius measurement. This formulas can greatly improve the accuracy of the measurement.

关 键 词：全站仪法 变化量的分析 修正公式的推导
