聚合物的流动取决于材料的本性，设备和加工条件，通常包括剪切流动，拉升流动和挤压流动并结合表面的封闭和自由流动。Translation8Thecontroloftheprocessandproductqualitymustbebasedonanunderstandingoftheinteractionsbetweenresinproperties,equipmentdesign,operationconditions,thermo-mechanicalhistory,microstructure,andultimateproductproperties.

材料加工和产品质量的控制必须建立在我们对树脂性能，试验设计，加工条件，热机械历史，微观结构和最终产品性能的相互关系的认识上。Translation9Shapingoperationinvolvecombinationsoffluidflowandheattransfer,withp
