【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.第一点,如果在聚乙烯中使用倾斜的层状添加剂会增加该体系表层起皮并脱落的话,那么这种能引起起皮的表面压力很明显不仅仅是只有在层状添加物垂直于全同聚丙烯时才会产生。 大致意思是:当层状添加剂倾斜存在于聚乙烯中时,体系的表层依然存在脱落现象,并且更严重了,所以想把层状添加物垂直于全同聚丙烯作为导致体系起皮脱落的论据是不充分的,甚至是错误的。 ![]() ![]() ![]() ![]() ![]() |
