摘　　要： 讨论了聚合物流体在挤出流动中的弹性行为及其起因 ,分析了弹性特性相互之间的关系 ,以及相应的定量描述 ,并就其进展作了简要的述评。 The elastic behavior and the mechanisms during extrusion flow of polymeric fluids were discussed, and the relationship among these elastic properties was analyzed in the present paper. The relevant quantitative expressions for prediction of these elastic properties and their correlations were introduced. Furthermore, the progress in this field was briefly reviewed.
