摘要 对近年来国内外关于熔体挤出不稳定流动现象的研究进展进行了介绍。阐述了关于形成鲨鱼皮和压力振荡及其他挤出不稳定流动的相关机理,并总结了抑制挤出不稳定现象所采取的措施。 The research progress of the flow instabilities in recent years at home and abroad is introduced in brief. The formation mechanism of sharkskin, press oscillation and so on are discussed. The improvement of flow instabilities is summarized.
