英语词汇“capillary action”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

capillary action n. the action or process by which a liquid within a narrow void in a solid (as a capillary tube or a porous material) moves or changes level as a result of the interaction of the liquid molecules with each other and with those of the enclosing solid; (also) the rise or fall of liquid caused by this process; cf. capillarity n.The direction of the movement or change in level depends on the relative attraction of the molecules of the liquid for each other and for those of the solid.
