【Original】who do you know this sentence?
|
|
On the first point ,if a system increases fold separation by adopting inclined lamellae as in polyethylene surface stress due to fold congestion is evidently more of a factor than when lamellae are always perpendicular as in isotactic polypropylene. It is too hard to understand this sentence for me. Who can help me? |

| Understanding this sentence needs some specific knowledge on polymer science which is a branch of modern chemistry. Form grammatical point of view, perhaps this sentence is not correct. The main clause of this sentence is that 'surface stress is evidently more of a factor'. Sometimes in papers published in so-called international academic journals there exist many grammatical mistakes, especially when the authors are from non-English spearking counturies. |

On the first point ,if a system increases fold separation by adopting inclined lamellae as in polyethylene. surface stress due to fold congestion is evidently more of a factor than when lamellae are always perpendicular as in isotactic polypropylene.第一點(diǎn)，如果在聚乙烯中使用傾斜的層狀添加劑會(huì)增加該體系表層起皮并脫落的話，那么這種能引起起皮的表面壓力很明顯不僅僅是只有在層狀添加物垂直于全同聚丙烯時(shí)才會(huì)產(chǎn)生。 大致意思是：當(dāng)層狀添加劑傾斜存在于聚乙烯中時(shí)，體系的表層依然存在脫落現(xiàn)象，并且更嚴(yán)重了，所以想把層狀添加物垂直于全同聚丙烯作為導(dǎo)致體系起皮脫落的論據(jù)是不充分的，甚至是錯(cuò)誤的。  |
