本文提出了一个新的1990年国际温标（ITS-90）上空气饱和水密度随温度变化的公式。此外，还提出了一个新的计算等温压缩系数的公式作为温度的函数ITS-90。该公式用于计算ITS-90上5 - 40 °C温度范围内的水密度，用于重量法测定容量标准品的体积。
A new formulation of the density of air-saturated water as a function of temperature on the 1990 International Temperature Scale (ITS-90) is presented. Also, a new equation for calculating isothermal compressibility as a function of temperature on ITS-90 was developed. The equations are to be used to calculate the density of water, in the temperature range 5 to 40 °C on ITS-90, used in the gravimetric determination of the volume of volumetric standards.
