正向渗透

研究了离聚体膜的气体正向渗透性能和CO2反向渗透行为，发现离聚体膜具有优越的CO2渗透性能和相对较差的O2渗透性能。

The permeability and CO2 reverse permeation behavior of the ionomer membrane were investigated . The results showed the ionomer membrane had better permeability for CO2 and relatively poorer permeability for O2 .

采用正向渗透试验方法测定了氯化钙和水玻璃溶液添加丁二酸钠后溶液在粉尘介质中的渗透规律。

The penetration law of a solution of calcium chloride , water glass and sodium succinate into dust is determined by the forward permeability test .

采用滴液法、正向渗透法和反渗湿润法分别研究了3种阴离子型湿润剂对10种硫化矿粉尘的湿润效果，比较了不同实验装置研究湿润剂湿润粉尘的相关性。

By using dropping liquid , downward penetration and upward capillary seep experiments to test three anionic wetting agents to ten dust samples of sulfide ores , their relevance of wetting effects was investigated .
