permeation rate meaning in Chinese

渗透速率

The pd membrane prepared by the modified electroless plating has a high h2 permeation rates , meantime exhibits a good h2 selectivity
由无电子电镀过程制备的钯膜对氢渗透速率高，对氢有良好的选择性。
The permeation rate of n2 , o2 , co2 , the thermal infrared emissivity and radar absorption of composite film were measured
在性能研究方面，测试了复合膜对n2 、 o2 、 co2的气体渗透速率的影响以及复合膜的热红外辐射和电磁波吸收性能。
Iontophoresis is a technique which the permeation rate of ionic drugs into the body is enhanced by applying an electric field between viable tissues
摘要离子电渗疗法是一种依靠在身体不同组织间施加电场来增加离子药物渗透率的技术。
It showed the effluence of composite film on the permeation rate of o2 is more obvious than that of n2 and co2 . but there is no apparent effect on their separation . compare with host film , thermal - infrared radiance of composite film decreased
结果表明fe3o4 / pvdf复合膜对于o2渗透速率的影响较n2 、 co2大，但对于三者分离效果不明显；纳米fe3o4的引入使得复合膜相对于pvdf基膜，热红外辐射率有所降低，并具有一定的电磁波吸收能力。
