Understanding "幅度" - Chinese Word Explanation

1. Basic Information

• Word: 幅度
• Pinyin: fúdù
• Literal Meaning: "width/breadth + degree/extent" — roughly "the measure of a span"
• Primary Meaning: range; extent; amplitude; scope (the degree or magnitude of change, movement, or variation)

2. In-depth Explanation

• Context and Usage:
  "幅度" is used to describe how much something changes, varies, or extends — often in relation to a measurable quantity. It is commonly used in contexts such as economics, physics, statistics, and everyday discussion about prices, temperatures, salaries, movements, and adjustments.
  In English, it corresponds to words like "range," "extent," "margin," "amplitude," or "degree," depending on the context. For example:
• 价格幅度 → price range / extent of price change
• 增长幅度 → growth margin / extent of increase
• 摆动幅度 → amplitude of swing (physics)

Nuance: "幅度" emphasizes the size or degree of a change or difference, rather than the absolute value. It answers the question "by how much?" rather than "what is the number?"

• Character Breakdown:
• 幅 (fú): Originally refers to the width of cloth or the breadth of a piece of fabric. By extension, it came to mean "width," "breadth," or "measure" of something. It is also used as a measure word for flat objects (e.g., 一幅画 — "a painting").
• 度 (dù): Means degree, extent, or measurement. It appears in words like 温度 (wēndù — temperature), 速度 (sùdù — speed), and 程度 (chéngdù — degree/level).

Combined, 幅度 literally paints a picture of "the measure of a span" — how wide or large a change or range is.

3. Example Sentences

• Chinese: 今年物价上涨的幅度比去年大。
• Pinyin: Jīnnián wùjià shàngzhǎng de fúdù bǐ qùnián dà.
• English: The extent of price increases this year is greater than last year.

• Chinese: 政府计划大幅度降低税收。
• Pinyin: Zhèngfǔ jìhuà dà fúdù jiàngdī shuìshōu.
• English: The government plans to reduce taxes by a large margin.

• Chinese: 这个地区的温差幅度很大，白天和晚上相差二十度。
• Pinyin: Zhège dìqū de wēnchā fúdù hěn dà, báitiān hé wǎnshang xiāngchà èrshí dù.
• English: The temperature range in this area is very large, with a difference of twenty degrees between day and night.

Cultural Notes

In Chinese media and formal writing, "幅度" frequently appears in economic reports and government announcements. For instance, you will often hear phrases like "大幅度调整" (dà fúdù tiáozhěng — "large-scale adjustment") or "小幅度增长" (xiǎo fúdù zēngzhǎng — "small increase"). This reflects a cultural preference for precise, measured language when discussing policy, statistics, or social changes.
Additionally, in physics and engineering, "幅度" is the standard translation for "amplitude" (e.g., 振幅 — zhènfú, literally "vibration amplitude"). This shows the word's versatility across both everyday and technical registers.

Conclusion

To remember "幅度" (fúdù), think of it as "the measure of how far something swings or changes." The character 幅 gives the sense of "breadth/width," while 度 gives the sense of "degree/extent." Together, they express the range or magnitude of change — whether it's prices, temperatures, salaries, or sound waves. Use "幅度" whenever you want to talk about how much something varies or shifts.
