weighting substances meaning in Chinese
加重物质
Examples
- As the temperature increases , the water flux first decreases evidently , then increases slightly and the clearance rates of low - molecular weight substances first increase , then decrease shaply
随着铸膜液温度的上升，水通量先是明显下降，然后略有上升。膜对低分子物质的去除率先是增加，然后急剧下降。 - As the concentration of pes solution increases , the pure water flux decreases and the clearance rates of low - molecular weight substances such as urea and creatintine first increase , then decrease , and increase slightly at last
随着铸膜液浓度的上升，水通量呈现总体下降的趋势；膜对低分子物质的去除率先上升，然后下降，随后又略有上升。 - The dual - bath coagulation method suggested by j . a . va n ' t hof could be used in membranes with high selectivity clearance rate of low - molecular weight substances and moderate water flux theoretically . therefore it may be applied in the field of hemofiltration . to improve and optimize the performance of the pes ultrafiltration membrane applied in the hf , here the flat membranes and hollow fiber ( hf ) membranes are made in certain conditions based on the dual - bath coagulation method where pes is used as the membrane material , dmso as solvent and pvp & peg as additives this paper includes five parts as follow : 1
为了改善和优化聚醚砜超滤膜(单浴法)在血液过滤实际应用中的性能，本论文以j . a . van ' thof等提出的双凝固浴法为基础，以聚醚砜( pes )为主要成膜材料，以二甲基亚砜为溶剂，并添加一定分子量的致孔剂( pvp ，聚乙烯吡咯烷酮)以及一定分子量的添加剂( peg ，聚乙二醇)按照一定配比在一定温度下制成透明均一的铸膜液，静置脱泡后在一定的工艺条件下制成聚醚砜平板膜和中空纤维膜，然后通过测试膜的结构和性能来评估其用于血液过滤中的前景。
