Some of the liquid spills out through the capillary constantly with the rise of the temperature of the content. Wipe away the overflown liquid with a piece of filter paper at any time until the fluid does not overflow anymore. Remove the pycnometer from the water bath rapidly. Proceed as described under method (1), starting from the words "clean off any material on the outside with a piece of filter paper…".

Experiment shows that both the dry plate pressure drop and the wet plate pressure drop increase with the increase of the kinetic energy factor in plate hole but have no influence of the height of cap. The wet plate pressure drop linearly ascends as the clear liquid height increases. Liquid lift-up increases at first then decreases with the increasing of the kinetic energy factor in plate hole, increases with the clear liquid height increasing and the height of cap decreasing, but as the kinetic energy factor in plate hole increased, the influence of height of cap will gradually decreased.

实验表明干板压降、湿板压降均随板孔动能因子的增大而增大，不受罩体高度变化的影响，湿板压降随清液层高度的增大而增大，成正比关系；液体提升量随板孔动能因子的增大先增大后减小，随清液层高度的增大而增大，随罩体高度的增大而减小，但随板孔动能因子的增加，罩体高度的影响逐渐变小；漏液量随板孔动能因子的增大迅速减小，随清液层高度的增大而增大，但接近漏液点时清液层高度的影响不明显。

Pore structure analysis shows that micropores can be adjustably generated on the mesopore wall of mesoporous carbon by post activation at high temperature using KOH as an activating agent.
