摘要
标准容积作为体积管的一个技术参数,是由校准状态下测得的容积经过压力和温度修正,换算到标准状态(20℃,101.325kPa)下的容积,是量值传递的基础。通过对压力和温度修正公式,水的膨胀系数的推导与计算,建立膨胀系数公式和相关数据的一一对应关系。
The standard volume as a technical parameter of the pipe prover is a volume under the standard condition （20℃,101.325kPa） converted into with the volume measured under the proving condition through the pressure and temperature correction, is a basis for magnitude transmission. The corresponding relations one by one between the formula to the expansion coefficient and the relative data have been established through the derivation and calculation of the expansion coefficient of the water in the formula to correct the pressure and the temperature in this article.
