介绍了一种基于数字全息干涉法测量二元液体相互扩散系数的方法。通过不确定度分析和实验验证，估计温度和互扩散系数的不确定度分别不大于±0.16 K和±0.2%。在此基础上，测定了常压下T = (278.15 ~ 338.15) K范围内碳酸二乙酯和己二酸二乙酯在庚烷中的相互扩散系数，并用实验数据拟合出多项式。
A method based on digital holographic interferometry for measuring the mutual diffusion coefficients of binary liquid is introduced. With uncertainty analysis and experimental verification, the uncertainties of temperature and mutual diffusion coefficient are estimated to be no greater than ± 0.16 K and ± 0.2 %, respectively. On this basis, the mutual diffusion coefficients for diethyl carbonate and diethyl adipate in heptane were measured from T = (278.15 to 338.15) K under atmospheric pressure, and a polynomial was fitted by the experimental data.
