英文科技论文写作中一些常见的技术问题
不宜使用长句子及不常见的词汇。 主从复合句必须有从句也有主句。 正确使用名词的单复数 有些常用名词无复数, 如:evidence,information,literature等。 有些词组中的名词必用复数:at different temperatures;with various methods; at high(low)temperatures 等。 不及物动词不可用被动语态。如不可用:was appeared,was occurred等。 不宜使用省略式词汇。如:does'nt, should'nt 等。 在两个或数个并列成分的最后两个中间加 and 连接。如:curve A,curve B and curve C。 's 只能用于表示人和动物的所有关系。不应使用:the catalyst's activity等表达 方式。
一些例子 Meanwhile, it found that NiO/Al2O3 was also a good partial oxidation of eth ane to syngas. Meanwhile, it was found that NiO/Al2O3 was also a good partial oxidation cat alyst of ethane to syngas.
It is well known that nickel based catalysts on Al2O3 are usually unstable a t high temperature. It is well known that nickel based catalysts on Al2O3 are usually unstable a t high temperatures.
In order to examine the stability of the catalyst for this reaction. The lif e test experiment was carried out. In order to examine the stability of the catalyst for this reaction, the lif e test experiment was carried out.
During the reaction, no ethene in the products was appeared. During the reaction, no ethene appeared in the product.
CO and CO2 selectivity were 93%, 7% respectively. CO and CO2 selectivities were 93% and 7% respectively.
XRD results revealed that the reduced nickel was presented in the used catal yst. XRD results revealed that the reduced nickel was present in the used catalys t.
It is well known that there exist pressure gap and material gap between the studies of single crystals in UHV system and the studies of real catalyst. It is well known that there exist the pressure gap and the material gap betw een the studies of single crystals in UHV systems and the studies of real ca talysts. But it is rather difficult to study the structures and properties of the def ects due to the lack of routine conventional methods. But it is rather difficult to study the structures and properties of the def ects due to the inability of routine conventional methods.
It possesses both lateral resolution and temporal resolution which are high enough to in situ and in real time observe processes following work function changes over mesoscopic surface areas. It possesses both lateral resolution and temporal resolution which are high enough to carry out in situ and real time observations in processes followin g work function changes over mesoscopic surface areas.
Compared with area (a) and area (b), the decrease of local work function on area (c) should'nt be attributed to the formati [1] [2] 下一页
