zjqstu2003(金币+5,VIP+0):呵呵,谢谢回复!我主要是看看有没有语法错误 10-8 11:10
“研究和讨论了焙烧温度、活性组分负载量以及不同前驱体对NOx转化率的影响”这句话如何翻译。
下面这段话里:以纳米级锐钛矿型TiO2为载体,MnOx为活性组分,制备了低温MnOx/TiO2体系SCR催化剂,研究和讨论了焙烧温度、活性组分负载量以及不同前驱体对NOx转化率的影响。利用TG-DSC,XRD,SEM,EDS对催化剂体系及其晶相组成进行表征,采用模拟烟气分析装置测试催化剂的活性。结果表明:以乙酸锰为前驱体,当焙烧温度为400℃,Mn负载量为20%,分解的主要产物为MnO2。在低温范围内,催化剂的反应温度从160℃开始,脱硝性能比较好,其NOx转化率一直都在80%以上。该体系具有良好的低温SCR活性。
翻译是这样的,请教有没有语法错误:欢迎指正。
Low temperature SCR catalysts of MnOx/TiO2 was prepared based on nano-meter anatase TiO2 as supporter and MnOx as active component. The paper focus on how operation parameters such as temperature, the loading of active component and different precursor affect the conversion of NOx. The catalysts were characterized by of TG-DSC, XRD, SEM, EDS and the catalytic activities were examined with the device of simulated flue gas. It shows that With manganese acetate as the precursor, the calcination temperature at 400℃, the charge number[负载量] of Mn  20%, the decomposition product was mostly MnO2. At low temperature, it was found that when the reaction temperature exceeds 160℃,the conversion rate of  NOx has been above 80% under the the conditions. It showes an excellent catalytic activity at low temperature

我也不知道对不对。你参考看看。
还有像这种文摘你应该看别人英文文献是怎么说的,不要写了中文再翻译过来。那样不会地道

zjqstu2003(金币+5,VIP+0):谢谢,你看这么说对吗?The paper focus on the effect of temperature,the weight of active component and different precursor on the conversion of NOx。摘要整体的翻译有语法错误码? 10-8 10:47

zjqstu2003(金币+1,VIP+0):我想说这几个条件同时对对NOx转化率产生影响。 10-8 11:05
effect 放在温度前面好吗?你强调的是温度还是温度效应?

The influence of cobalt loading (10–40 wt%Co), cobalt precursor, and promoters (Re,Mn) on the physico-chemical and catalytic properties
of mesoporous Co/SBA-15 catalysts for the Fischer–Tropsch Synthesis (FTS) reaction (T = 493 K, P = 20 bar, H2/CO = 2) has been
investigated. Catalysts were characterized by N2 and Ar adsorption, X-ray diffraction (XRD), transmission electron microscopy (TEM),
X-ray photoelectron spectroscopy (XPS), and temperature-programmed reduction (TPR). For Co/SBA-15 catalysts prepared from Co(II)
nitrate the dispersion decreased and the extent of cobalt reduction increased with cobalt loading. A maximum CO conversion was found
for the sample with ca. 30 wt% Co loading, though the intrinsic activity of Co remained constant in the range of Co loading studied. More
methane and less C5+ n-paraffins were produced over the less reducible 10 wt% Co loading sample. The addition of ca. 1 wt% Re enhanced
the reducibility of cobalt oxides and increased the catalyst activity, though the intrinsic activity of cobalt sites was not altered. Rhenium
also favored the formation of long-chain n-paraffins (C10+) while decreasing methane selectivity. Promotion of cobalt with ca. 2 wt% Mn
significantly improved cobalt dispersion but decreased its reducibility, producing catalysts that were less active than the unpromoted one.
At similar cobalt loading (ca. 20 wt%), a much better dispersion and a stronger cobalt–support interaction leading to the formation of lowreducible
cobalt silicates was observed for oxidized samples prepared from acetate and acetylacetonate precursors as compared to that derived
from cobalt(II) nitrate, as evidenced by TEM, XPS, and TPR. The former catalysts were characterized by a low FTS activity and a product
distribution shifted toward the formation of lighter products. Finally, at comparable Co loading Co/SBA-15 catalysts (nitrate precursor) were
about 1.5 times more active per weight of total Co than a Co/SiO2 sample, with only minor differences in product selectivity.

这是我们方向大牛的论文摘要。我虽然和楼主做的东西不同,但都是多向催化,用的表征手段,以及常用的专业术语基本一样的。其实楼主应该找你这个方向的类似论文来套,毕竟你做了实验,肯定看了不少文献,很多人的第一篇英语文章都是这样弄出来的。等你打英文就像打中文这么熟练的时候,就可以抛掉这些了。写好了,再找英语好的同学老师帮修改,比你在网上浪费时间好。
精韧不怠,日进有功
