摘要
论述了高聚物熔体在喷丝孔区的流变性及粘弹行为。具体分析了喷丝孔直径与剪切速率及喷丝头拉伸倍数之间的关系，提出了喷丝孔直径的选择依据。
The rheological and viscoelastic behavior of polymer melts in the die zone are expounded. The relations between spinneret diameter and spinneret draft and shearing rate are analysed concretly. The select foundation of spinneret diameter are advanced.
