本文报道了在（293.15 ~ 353.15）K和（1 ~ 10）bar压力范围内，用Loschirm池结合全息干涉法测量氩-氖、氪-氦、氨-氦、氧化亚氮-氮和丙烷-氦气体系统的二元扩散系数数据。对惰性气体系统的研究旨在通过将作为温度和压力的函数测量的二元扩散系数与理论数据进行比较来验证测量装置。在之前的研究中，已经表明，如果在扩散过程之前使用纯气体，则使用应用设置测量的原始浓度相关数据会受到系统效应的影响。因此，处理浓度依赖性测量数据以获得平均摩尔分数为0.5的平均二元扩散系数。分子气体系统的数据完成了对技术感兴趣的小研究系统的文献数据，并指出了所应用的测量设备的能力。进一步的实验数据报告系统氩氦，氪氩，氪氖，氙氦，氙氪，一氧化二氮二氧化碳，丙烷二氧化碳在293.15 K，2巴，和平均摩尔分数为0.5。
The paper reports on binary diffusion coefficient data for the gaseous systems argon–neon, krypton–helium, ammonia–helium, nitrous oxide–nitrogen, and propane–helium measured using a Loschmidt cell combined with holographic interferometry between (293.15 and 353.15) K as well as between (1 and 10) bar. The investigations on the noble gas systems aimed to validate the measurement apparatus by comparing the binary diffusion coefficients measured as a function of temperature and pressure with theoretical data. In previous studies, it was already shown that the raw concentration-dependent data measured with the applied setup are affected by systematic effects if pure gases are used prior to the diffusion process. Hence, the concentration-dependent measurement data were processed to obtain averaged binary diffusion coefficients at a mean mole fraction of 0.5. The data for the molecular gas systems complete literature data on little investigated systems of technical interest and point out the capabilities of the applied measurement apparatus. Further experimental data are reported for the systems argon–helium, krypton–argon, krypton–neon, xenon–helium, xenon–krypton, nitrous oxide–carbon dioxide, and propane–carbon dioxide at 293.15 K, 2 bar, and a mean mole fraction of 0.5.
