测定了常压下温度为278.15~338.15 K时碳酸二甲酯在正庚烷和空气中的质量扩散系数。实验使用的是本课题组研制的数字全息干涉计量学系统。为了验证该系统的准确性和可靠性，测量了温度为298.15 K、冷凝温度为0.33m ol·L−1条件下氯化钾在标准水溶液中的质量扩散系数。温度和质量扩散系数的实验不确定度估计分别不大于±0.16K和±0.2%。
The mass diffusion coefficients of dimethyl carbonate in heptane and in air were measured at T = (278.15 to 338.15) K under atmospheric pressure. The experiments were carried out using a digital holographic interferometry system that was constructed by our group. The mass diffusion coefficient of KCl in standard aqueous solution at a temperature of 298.15 K and condensation of 0.33 mol·L−1 was measured to verify the accuracy and reliability of the system. The experimental uncertainties in temperature and mass diffusion coefficient are estimated to be no greater than ± 0.16 K and ± 0.2 %, respectively.
