科技写作要求严谨，明确.为了严格定义一个事物，往往要加上限制性的修饰词或短句.比如描写实验用的 mice 时 ， 一般不会只说 mice ， 而是用类似 “NCI-H23 tumor bearing female athymic nude mice” 的描述 . 前面有5个修饰词来定义研究用的mice 这时一般把最窄的定义写在最前面，最广的定义写在后面.修饰语要靠近同被修饰的对象 . 因修饰语和被修饰的词被隔开， 而造成意思混乱的情况很多 . 下面是一些例 子 .

用 which 开头的修饰句 , 是要修饰 reducing power , 而不是修饰 electron donating capacity , 所以要紧跟在 reducing power 后面 .
宜改为： Reducing power, which may serve as a significant indicator of potential antioxidant activity, represents the electron donating capacity. 或 : Reducing power represents the electron donating capacity. It may serve as a significant indicator of potential antioxidant activity.
