“reduce”是英语中常用的动词,其核心含义为“减少、降低”,但在不同语境下具有多重延伸意义。以下是基于权威语言学和专业领域来源的详细解释:
基本含义:数量或程度的减少
在通用语境中,“reduce”表示使某物的数量、尺寸或程度变小或变少。例如:“The company aims to reduce carbon emissions by 30%”(公司计划减少30%的碳排放)。该定义参考了《牛津英语词典》对“reduce”作为“make smaller or less in amount”的释义。
化学领域:还原反应
在化学中,“reduce”指物质获得电子或失去氧原子的过程,与“氧化反应”相对。例如,铁矿石通过还原反应转化为金属铁(Fe₂O₃ + 3CO → 2Fe + 3CO₂)。这一用法在《剑桥化学术语词典》中被定义为“a substance gaining electrons during a reaction”。
数学与逻辑:简化或归类
数学中,“reduce”可表示将分数、方程等简化至更简形式,如将2/4约分为1/2。在逻辑学中,它指将复杂命题转化为基础命题的过程,如《数学原理》(怀特海与罗素著)中提到的“归约公理”。
日常应用:状态或等级的降低
“reduce”还可描述降低事物的严重性或等级。例如:“台风强度 reduced from Category 4 to Category 2”(台风等级从4级降为2级);或职场中“被降职”(be reduced to a lower position)。《韦氏词典》将此释义标注为“degrade in rank or status”。
生物学与医学:体型或病理的减轻
在生物学中,“reduce”描述器官退化(如人类阑尾的进化缩小);医学领域则用于表示症状缓解,如“通过药物 reduce inflammation”(减轻炎症)。该用法被《朗文医学辞典》收录为“lessen the severity of a condition”。
