聚合物的流動(dòng)取決于材料的本性，設(shè)備和加工條件，通常包括剪切流動(dòng)，拉升流動(dòng)和擠壓流動(dòng)并結(jié)合表面的封閉和自由流動(dòng)。Translation8Thecontroloftheprocessandproductqualitymustbebasedonanunderstandingoftheinteractionsbetweenresinproperties,equipmentdesign,operationconditions,thermo-mechanicalhistory,microstructure,andultimateproductproperties.

材料加工和產(chǎn)品質(zhì)量的控制必須建立在我們對(duì)樹(shù)脂性能，試驗(yàn)設(shè)計(jì)，加工條件，熱機(jī)械歷史，微觀結(jié)構(gòu)和最終產(chǎn)品性能的相互關(guān)系的認(rèn)識(shí)上。Translation9Shapingoperationinvolvecombinationsoffluidflowandheattransfer,withp
