[交流] 求助一段翻译

摘  要:选用氯金酸(AuCl3.HCl.4H2O)和聚乙烯醇(PVA)为基本原料,还原生成了纳米金颗粒,研究了氯金酸与聚乙烯醇的反应的动态过程,制备了PVA-Au纳米复合膜,分析了复合膜材料中纳米金颗粒对PVA膜的热稳定性能的影响。结果表明:PVA制备纳米金颗粒到反应2.5小时为宜;PVA与氯金酸的反应是-OH将Au(Ⅲ)还原为Au而转化为=O的过程;DSC和TG图谱表明温度和浓度升高都能提高PVA膜的热稳定性能。




谢谢啦

The paper synthesize nano-gold particles through reacting chloroauric acid (AuCl3.HCl.4H2O) with polyvinyl alcohol (PVA) , and then study the dynamic process of this reaction . we produce PVA-Au nano-composite membrane , at the same time we analyze how nano-gold particles impact on the thermal stability of the composite membrane material PVA. The survey indicates that 2.5 hours is the most appropriate time for producing nano-gold particles from PVA; when PVA reacts with chloroauric acid,  Au(Ⅲ)is reduced to Au,while hydroxyl group (-OH) is changed into carbonyl group(=O); the diagram of  DSC and TG show that increasing temperature and concentration can improve thermal stability of PVA membrane.

the paper 是不会合成的,主语不对,可以换成in this article, we synthesized.

而且句中单复数不匹配
