在学术论文里,有是很难顾及数上的逻辑。但一般不将逻辑上的问题视为语法错误。只须注意在一个句子中的数和谓语动词的统一即可。
单、复数的选用有一些非定性、但可供参考的趋向:
◆当含意上强调复数时建议用复数。
The catalyst concentrations for the different reactions are different.
Our research focuses on the syntheses and characterizations of a series of polycarbonates with different chemical structures.
The physical and chemical properties of pound have been studied.
The chain lengths of the oligomers with different molecular weights are different.
当含意上不强调复数时可用单数或复数。
Our research focuses on the synthesis of polycarbonates.
The property of pounds in group 1 is different from the property of pounds in group 2.
The chain length of the oligomers increases with increasing reaction time.
◆在标题、小标题中或描述一类事物、现象等时:当提到具体物质时常用复数。
2-1 Polyesters
Polymers are macromolecules built up by large numbers of small molecules. The small molecules bine with each other to form polymer molecules are termed monomers.
在标题、小标题中或描述一类事物、现象等时:当提到抽象概念时可用单数、也可用复数。
2-11 Step Copolymerization
2-12 Newer Types of Step Polymerizations
This chapter will consider the characteristics of step polymerization in detail.
