所有研究热扩散的实验工作者都研究过含二氧化碳的混合物。然而，我们发现，含有这种气体的混合物似乎仍然呈现出新颖而有趣的特征。这些特殊功能的帐户将在这项工作中。在先前的一系列实验中，发现kt，即热扩散系数与普通扩散系数的比率，通常在低温下趋于逐渐减小。因此，我们决定做进一步的实验，目的是找出在高温下kt是否也会发生变化。最初的目的是对工作温度高达约750° C的多种气体混合物进行普查。或1000° C。这项工作开始后，卢格发表了一份报告，他的实验表明，kt的混合物的氢和二氧化碳是更大的高温比它是在常温下。这一贡献的主题提供了一个有价值的联系之间的结果得到的埃利奥特和马森和较低的结果，我们以前得到的使用，较小的温度范围。从他的结果卢格得出结论，有一个逐步增加，在kt的温度升高。
All experimental workers on thermal diffusion have examined mixtures containing carbon dioxide. We find, however, that mixtures containing this gas still appear to present novel and interesting features. An account of these special features will be given in this work. In a previous series of experiments it was found that kt , the ratio of the coefficient of thermal diffusion to the coefficient of ordinary diffusion, generally tends to decrease gradually at low temperatures. We decided, therefore, to make further experiments with the object of finding whether any change in kt also occurred at high temperatures. The original intention was to make a general survey of a number of gas mixtures working up to about 750° C. or 1000° C. After this work was begun Lugg published an account of his experiments showing that kt for a mixture of hydrogen and carbon dioxide is greater at high temperatures than it is at ordinary temperatures. This contribution to the subject furnished a valuable connection between the results obtained by Elliott and Masson and the lower results we had previously obtained using a, smaller range of temperature. From his results Lugg concluded that there is a gradual increase in kt as the temperature is raised.
