随着聚醚砜相对分子质量和含量增大，膜的水通量减少而对牛血清白蛋白的截留率提高。
With the growth of the content and molecular weight of polyethersulfone, its water flux is reducing, and the retention ratio of bovine serum albumin is increasing.
本发明的共混膜具有低收缩、高通量、截留相对分子质量可调节的优点。
The blend membrane of the invention has the advantages of low contraction, high flux, adjustable cut-off relative molecular mass.
