众所周知,英语中的每个句子都以大写字母开头。在其他一些情况下,使用大写或小写字母的选择可能不那么明显。
以小写字母开头的术语
首先,总是以小写字母开头的术语必须保留其小写字母,即使是在句子的开头。
• mRNA samples were collected.
• pH values ranged from 3.0 to 5.8.
正如我们在文章《有机化学与药物化学的英语论文撰写》中所述,这也适用于带有斜体小写首字母的化学名称(例如,cis-、trans-、ortho-、tert-、n-或i-)。不过,在这些情况下,化合物名称的第一个字母(词根)将被视为标准单词(即在句子开头大写)。
• tert-Butanol was added to the mixture.
• BUT Additional tert-butanol was required to complete the reaction.
带冒号的句子
如果冒号(:)后的第一个单词是一个独立分句的开头,则该单词可以大写,但并非必须大写。如果冒号后有几个独立分句,则每个分句都应大写。
• This study examines the following question: What is the precise deformation and stress map of the steel cords within a TBR tire under actual working conditions?
• This study examines the following questions: What is the precise deformation and stress map of the steel cords within a TBR tire under actual working conditions? What are the effects of that deformation on tire performance? How can that deformation be diminished?
• BUT: This study measures several parameters: height, frequency, and wavelength.
我们希望这些提示能帮助你在写作时决定何时将单词大写。如有任何问题或意见,请告诉我们。AJE祝您好运!
