[求助] 求助汉翻英。欢迎指正错误。。高分子材料方面

高分子材料方面求指正改正。。。。


对于HEC,在HEC用量为5g、醚化剂用量为7.5g、碱用量1.85g、在65℃下反应2小时,得到的QHEC取代度最优为0.61,反应效率为64%;对于PVA,在PVA的浓度为5%、醚化剂用量为7g、碱用量2.5g、在65℃下反应6小时,得到的QPVA取代度最优为3.95。
For HEC, the HEC dosage of 5g, etherification agent is 7.5g, alkali 1.85g, at 65 ℃ for 2 hours, the optimal degree of substitution obtained QHEC 0.61, the reaction efficiency was 64%; for the PVA, the PVA concentration of 5%, etherification agent is 7g, alkali 2.5g, at 65 ℃ for 6 hours, get QPVA optimal degree of substitution 3.95.

那怎么改呢??我分不清。。。。。

前两句我认为不恰当的地方已经改了~。呵呵。就是贴上去的。
第三局和第四局实在是看着有点分不着头脑。
“对于HEC,在HEC用量为5g、醚化剂用量为7.5g、碱用量1.85g、在65℃下反应2小时,得到的QHEC取代度最优为0.61,反应效率为64%;改为:
HEC, etherification agent and alkali were added in to the reaction with the amounts of which were 5g, 7.5g and 1.85g respectively. The reaction will last 2 hours at the temperature of 65 ℃, and the optimal degree of substitution will be up to 0.61 with the reaction efficiency of 64%.

下一句你应该可以了吧~,也许我写的也不多,相互交流吧~,O(∩_∩)O~

我表示看英语我要看疯了,我预感我的六级又要悲剧了
心若没有栖息的地方,到哪里都是流浪……

PVA and HEC are water-soluble. We used 3-chloro-2-hydroxypropyl trimethyl ammonium chloride as etherifying agent to introduce quaternary ammonium groups into the structure of PVA and HEC through quaternization reaction to prouduce quaternized QPVA and QHEC, respectively.
The effect of reaction conditions on the degree of substitution and reaction efficiency were studied.
For HEC, the HEC dosage of 5g, etherification agent is 7.5g, alkali 1.85g, at 65 ℃ for 2 hours, the optimal degree of substitution obtained QHEC 0.61, the reaction efficiency was 64%.(这句话没有谓语)好好改改~
for the PVA, the PVA concentration of 5%, etherification agent is 7g, alkali 2.5g, at 65 ℃ for 6 hours, get QPVA optimal degree of substitution 3.95.
(同上)
