摘要：采用Mach - Zehnder干涉法，在压力为5.0 ~ 12.5 MPa、温度为273.25 ~ 284.15 K、CO2质量分数为0.061的条件下，测量了CO2溶液的密度。结果表明，在相同压力和温度下，CO2溶液与纯水的密度差与CO2质量分数呈单调线性关系。经实验数据拟合计算，该线性函数的斜率为0.275。
Abstract: The density of CO2 solution was measured by using Mach‐Zehnder interferometry in the pressure range from 5.0 to 12.5 MPa, at temperatures from 273.25 to 284.15 K, and CO2 mass fraction in solution up to 0.061. It was found that the density difference between the CO2 solution and pure water at the same pressure and temperature is monotonically linear with the CO2 mass fraction. The slope of this linear function, calculated by experimental data fitting, is 0.275.
