首次测定了干纤维素和木浆的润湿热。测定了纤维素初始含水量对润湿热的影响。它表明，当水作为部分解吸的结果被留下时，获得更高的值。测定了木粉和不同木浆的润湿热。计算了吸附热，并从纤维素物理结构的角度对所有数据进行了讨论。对氢氧化钠的吸附热进行了一些初步的测量。使用旋转绝热量热计的实验技术被证明是令人钦佩的适用于这种测量。
The heats of wetting of dry cellulose and wood pulp have been measured for the first time. The influence of the initial water content of the cellulose on the heat of wetting has been determined. It is shown that when the water is left as a result of partial desorption a higher value is obtained. The heats of wetting of wood meal and different wood pulps have been determined. The heats of adsorption were calculated, and all the data are discussed from the point of view of the physical structure of cellulose. A few preliminary measurements of the heat of adsorption of sodium hydroxide were made. The experimental technique of using a rotating adiabatic calorimeter is shown to be admirably adapted for measurements of this kind.
