例句 Example

近期《财经》杂志中，作者邱晓华在一篇文章中是这样用这个词的：「回顾改革开放以来中国经济运行轨迹，每隔十年出现一次波动与调整，大致经历四个周期……虽然波动与调整的程度与时间不完全相同，但引致波动的主要原因基本相似。」这里说的是中国经济每隔十年会经历一次周期性的起伏变化。

In a recent article in Caijing Magazine, author Qiu Xiaohua used the term like this: 'Looking back at the trajectory of China's economic operation since the reform and opening up, there has been a fluctuation and adjustment every ten years, roughly going through four cycles... Although the degree and timing of the 波动 are not exactly the same, the main reasons causing the 波动 are basically similar.' Here, it refers to the periodic ups and downs that the Chinese economy experiences every ten years.

波动和“起伏”“震荡”意思相近，但用法不同：“起伏”多用于具体事物（如地形），震荡强调剧烈震动（如股市震荡），而波动更侧重规律性的不稳定变化。这个词源自水波运动的意象，如今广泛用于经济、物理、心理学领域，比如“情绪波动”“价格波动”。

波动 (bō dòng) is similar in meaning to 起伏 (qǐ fú) and 震荡 (zhèn dàng), but their usage differs: 起伏 (qǐ fú) is often used for concrete things (like terrain), 震荡 (zhèn dàng) emphasizes violent shaking (like stock market turbulence), while 波动 (bō dòng) focuses more on regular, unstable changes. The term originates from the imagery of water wave movement and is now widely used in economics, physics, and psychology, such as in 情绪波动 (qíng xù bō dòng - emotional fluctuations) and 价格波动 (jià gé bō dòng - price fluctuations).
