埃 🔊

网络内容摘要 (Web Content Summary):

埃（拼音：āi）本意为“尘土、灰尘”，现代汉语中多用于表示极细小的尘埃或测量单位（如“埃”= 10^-10米，英文为 angstrom）。 “埃” (pinyin: āi) originally means "dust" or "dirt". In modern Chinese, it's often used to refer to tiny particles of dust or as a unit of length (Angstrom, 10^-10 meters).

据汉字字源学，“埃”字的结构含有“土”，表达与灰尘、微粒有关的含义。其象形起源与细小尘土相关。日常生活中，“埃”常见于表示极小、微观的事物。 Etymologically, the character contains the radical "土" (earth), emphasizing its relation to dust or particles. Its pictographic origin is connected to tiny earth particles. In daily use, it often describes extremely small or microscopic things.

• 常见用法：“埃”用作物理单位（埃/Å），在科学领域常见；也可指“灰尘”（如“尘埃”）。 Common Usage: "埃" is used as a physical unit (Ångström/Å) in science; it can also mean "dust", as in “尘埃” (chén āi, "dust" or "particle").
• 易混淆点：“埃”容易与“哀”（āi，悲哀）混淆，注意二者含义和用法完全不同。 Common Confusion: "埃" can be confused with "哀" (āi, "sorrow")—their meanings and usages are entirely different.
• 相关词语：尘埃（dust）、埃及（Egypt）、浮埃（floating dust）、埃垢（dust and grime）。 Related Words: 尘埃 (dust), 埃及 (Egypt), 浮埃 (floating dust), 埃垢 (dust and grime).

成语/文化背景：暂无特别流行的成语以“埃”为核心，但“尘埃落定”表达“事情尘埃落定”，隐含“埃”引申意义。部分外来地名及术语音译借用“埃”字，如“埃及”。 Idioms/Cultural Background: There are no major idioms with "埃" as the main character, but in “尘埃落定” ("when the dust settles"), "埃" carries an extended meaning. It's also used phonetically in some foreign names, e.g. "埃及" (Egypt).
