The simple setup was realized to analyze samples of water vapor collected from the solid surface adsorbent in the form of corundum ceramic balls. The adsorbent was previously saturated with water vapor from a source of distilled liquid water without dissolved gases. Testing of samples is carried out in a glass vessel isolated from the adsorbent by means of a forced change of pressure of vapor in the vessel. The necessary pressure rise occurs at the moment when steam is let into the vessel and the pressure drops during the vacuum pumping of water vapor. It was found that the samples respond differently to the rate of pressure change. This characteristic of gaseous mediums is associated with a significant quantity of discharged water molecules. It was found that the tested samples are clearly divided into two types according to the rate of pressure change. The first few samples behave in a similar way, but the behavior of the remaining samples is very different. It depends on the ...

在室温下接近饱和压力的水蒸气中自相似效应观察实验

实现了简单的设置,以分析从刚玉陶瓷球形式的固体表面吸附剂中收集的水蒸气样品。吸附剂预先被来自蒸馏液态水源的水蒸气饱和,而没有溶解气体。样品的测试是在玻璃容器中进行的,该玻璃容器与吸附剂隔离,通过容器中蒸汽压力的强制变化来进行。必要的压力上升发生在当蒸汽进入容器中并且在真空泵送水蒸气期间压力下降时。发现样品对压力变化速率的反应不同。气态介质的这种特性与大量排出的水分子有关。已经发现,根据压力变化率将测试样品清楚地分为两种类型。前几个样本的行为类似,但是其余样本的行为却大不相同。这取决于...
