如何表達倍數

論文里常用的句型舉例如下：

• The diameter of A was 3 times that of A』.
• The risk for cigarette smokers was 3 times that for non-smokers.
• Its activity was 3 times the normal value.
• This disease was 3 times more common in exclusively formula-fed babies than in those fed breast milk alone.
• Individuals with the metabolic syndrome were 3 times more likely to die of heart disease thanhealthy counterparts.

* 以上兩句中，有的人理解成「高出3倍」（比如前者40%，後者10%），有的人理解成「是3倍」（比如前者30%，後者10%），關於這一點連母語人士也不統一，所以可以表達成如下形式來避免歧義：

• This disease was 3 times as common in exclusively formula-fed babies as in those fed breast milk alone.
• Individuals with the metabolic syndrome were 3 times as likely to die of heart disease as healthy counterparts.

兩個常用的動詞搭配

A cell line was established; lentiviral vectors carrying ** gene were constructed.

又一個可以考慮省略的詞

中文裡有些詞不一定要譯出，如「技術」和「方法」等，這個之前提過。還有個詞也通常不用譯出，那就是「情況」。比如：「了解職業應激情況」不用譯成to investigate the condition of occupational stress，直接譯成to investigate the occupational stress即可。

又一個不要隨便加s的詞

Complement作補體講時，後面不加s，但可以寫成complement components；具體表達如：complement (C3 and C4) 或 complement C3 and C4。
