water permeability

基本解釋

Vasopressin is a hormone secreted from the posterior pituitary and regulates water excretion from the kidney by increasing water permeability of the collecting duct.
加壓素是由垂體后葉分泌的激素，在腎臟通過提高集合管對(duì)水的通透性來調(diào)節(jié)水的排泄。
The results of durability test show that the water permeability of HPLWAC is very low, and the frost resistance of HPLWAC is better than that of normal density concrete.
耐久性實(shí)驗(yàn)證明，高性能輕集料混凝土水的滲透性很低，并且該混凝土的抗凍性優(yōu)于普通重度的混凝土。
It pointed out that, the water permeability test, the chloride permeability test and the air permeability test are suit for different situation and they can not be replaced each other.
認(rèn)為水滲透性試驗(yàn)、氯化物滲透性試驗(yàn)、空氣滲透性測(cè)試各適合于不同的場(chǎng)合和情況，不存在某一種強(qiáng)于另一種的問題。

滲透系數(shù)
The result indicates that water permeability reduced with time. Concrete permeability increased with crack width, the degree of the permeability increase depends on the value of crack width in concrete.
結(jié)果表明,帶裂縫混凝土的滲透系數(shù)隨測(cè)試時(shí)間的增加呈遞減趨勢(shì),且遞減速度較快;混凝土的滲透性隨裂縫寬度的增加而增加,增加的程度取決于裂縫的大小。
化學(xué)
水滲透性
Those copolymers are widely used in petroleum recovery, textile, fine chemical, paper making, ethylene industry, life and medical science etc, because of their excellent dyeability, hydrolytic stability, water permeability and bonding property.
它的自聚物或共聚物由于具有良好的染色性、抗水解性、水滲透性和粘合性,可廣泛應(yīng)用于石油開采、精細(xì)化工、紡織、造紙、乙烯工業(yè)、生命科學(xué)和醫(yī)藥科學(xué)等諸多領(lǐng)域。
