“不同文章时态可能不一样” 楼主你这句话不对！
科技文章的不同部分的时态要求基本是固定的，如对摘要，前言，实验部分，讨论部分的时态都是有具体的限制的，说是八股文也可以。

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

The paper focus on the operation parameters such as temperature,
the weight of active component and the effect of different precursor on the  fractional conversion of NOx

人生的最大遗憾莫过于错误地坚持了不该坚持的，轻易地放弃了不该放弃的……

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？

zjqstu2003(金币+5,VIP+0):谢谢！我就是这么找的，但不同文章时态可能不一样，我投了后，专家说有语法错误让我修改。所以才贴网上的。 10-8 11:08

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。
