摘　　要：本文探讨新型荷正电非对称膜浓缩明胶水溶液,蒸发时间和添加剂LiCl浓度对明胶截留率的影响。实验结果表明:延长蒸发时间,可制得对明胶截留率高的膜;添加剂LiCl浓度增加,膜对明胶截留率降低。The paper is dedicated to the effect of evaporation time and the concentration of the LiCI additive on gelatin intercepting rate when gelatin solution is concentrated with the new positively charged asymmetric membrane.
