"Decrease" 是一个英语常用词,既可作动词也可作名词使用,核心含义指事物在数量、程度或强度上的减少。根据牛津大学出版社发布的《牛津高阶英语词典》,其动词形式读作/dɪˈkriːs/,表示"变得或使某事物变少或变小";名词形式读作/ˈdiːkriːs/,指"减少的过程或结果"。
在专业领域应用中,剑桥大学英语语料库数据显示,该词常见于统计学(如"a 15% decrease in sales")、生物学(如"population decrease")及工程技术场景(如"temperature decrease")。美国国家航空航天局(NASA)在2023年气候报告中,使用该词描述北极冰盖面积的年度变化:"The observed decrease in sea ice extent exceeds model projections by 20-30%"。
词性转换遵循规则变化:动词现在分词为"decreasing",过去式为"decreased"。其近义词包含"diminish"(逐渐减少)、"decline"(数量下降)和"reduce"(人为减少),反义词则有"increase"(增加)和"escalate"(升级)。根据《韦氏词典》词源考据,该词源自中古法语"decreistre",由拉丁语"decrescere"演化而来,词根"de-"(向下)与"crescere"(生长)组成。

reduce | 强调人为主动减少,多用于技术或管理场景。 | Reduce plastic use to protect the ocean. |
diminish | 侧重逐渐减弱或重要性降低,常描述抽象事物(如信心、资源)。 | Natural resources are diminishing. |
