摘要 介绍了熔体流延过程中的拉伸共振现象、拉伸共振形成的机理以及在牛顿流体和粘弹性流体中拉伸共振现象的研究进展 ,讨论了加工参数 (拉伸比、纵横比和空气间隙等 )和聚合物弹性对拉伸共振的影响。 The phenomenon of draw resonance in film casting process was introduced.The mechanism of draw resonance and development progress of draw resonance of the Newtonian fluid and viscoelastic polymer were reviewed.The processing parameters affecting the draw resonance(draw ratio,aspect ratio and air gap,etc.)and polymeric elasticity were discussed in detail.
