It is found that, with the increase of bore fluid flow rate, the mechanical properties decrease gradually, the pure water permeation flux increase obviously while the retention keeps almost constant for the membranes.

• 实验结果表明:随着内凝固浴流速的提高,纤维外径略有下降、内径有较大程度的提高、壁厚减小,其它结构无明显变化。 与此相对应,膜的力学性能有一定程度的下降,而水通量有很大程度的提高,截留率变化不大。
