Definition in Chinese

衰减是指作用、影响或效果随时间或条件变化逐渐变弱的过程，既可指物理量，也可用于抽象概念。shuāi jiǎn shì zhǐ zuò yòng yíng xiǎng huò xiào guǒ suí shí jiān huò tiáo jiàn biàn huà zhú jiàn biàn ruò de guò chéng jì kě zhǐ wù lǐ liàng yě kě yòng yú chōu xiàng gài niàn

Word origin

The compound joins 衰 (shuāi, "weaken") with 减 (jiǎn, "reduce"), forming a term for a force or effect that steadily becomes less.

Usage tips

  • The word normally describes a gradual change rather than an instant failure, so a sentence using it usually identifies what is losing force.
