毛細張力 的英文怎麼說
中文拼音 [máoxìzhānglì]
毛細張力
英文
capillary te ion-
Capillarity ( capillary action ) the rise or fall of liquids in narrow tubes as a result of the surface tension of the liquid, which causes the water to adhere to solid surfaces, such as soil particles or the walls of xylem vessels
毛細現象（毛細管作用） ：由液體表面張力引起的液體在細管中上升或下降的現象，毛細現象引起水和固體表面的粘合作用，例如土壤顆粒或木質部導管壁。It may be a modified stoma with the guard cells permanently open so that water is lost passively by hydrostatic pressure, as in sea lavenders ( limonium ), or a glandular hair from which water is actively secreted, as in runner bean ( phaseolus )
這可能是由於氣孔的保衛細胞永久張開而使水分在靜水力的作用下被動排出，比如海薰衣草（補血草屬） ；也可能是由腺毛主動分泌水分到外部，比如紅花菜豆（菜豆數） 。When water in the soil or in the xylem is put under tension, due to the evaporation of water from a particular site ( which creates a water potential gradient in the direction of the evaporation ), capillarity enables water to overcome the cohesive forces within the water and move against gravity in response to the water potential gradient
當土壤中或木質部中的水受到張力作用時，由於特定部分水的蒸發（沿著蒸發方向形成水勢梯度） ，毛細現象可以使水克服水分子之間的內聚力並同時沿著水勢梯度逆著重力作用移動。Based on the theory of shrinkage, capillary force theory, the influence of road concrete additives in common use on surface tension of water is studied, and the results show that the influence of water reducer is very small whereas shrinkage - reducing agent and air entrainer can reduce surface tension of solution significantly. the relation between surface tension and additive dosage are non - linear relation. each additive has an obvious critical micelle concentration ( cmc )
從混凝土收縮的基本理論? ?毛細管張力理論出發，通過道路混凝土外加劑對水的表面張力的影響研究發現，減水劑對水的表面張力的影響很小，而減縮劑和引氣劑可以大幅度降低溶液的表面張力，溶液的表面張力隨外加劑的摻量呈非線性形式降低，而且都存在臨界膠束濃度。Vibration viscosity coefficient of fresh concrete with additives and mineral admixtures are tested. the results show that water reducer and air entrainer can reduce vibration viscosity coefficient while shrinkage - reducing agent has very small influence on it. proper quantity of citric acid, sodium glucaonate or carboxymethy cellulose can reduce vibration viscosity coefficient of fresh concrete
通過對選定的引氣劑和減縮劑對硬化混凝土的收縮性能的影響研究發現，引氣劑和減縮劑可以大幅度降低混凝土毛細孔中溶液的表面張力，對降低混凝土收縮具有顯著作用，當二者復摻時，減縮效果更為明顯。分享友人
