- damped oscillation
- 阻尼振荡
- The pendulum shows a damped oscillation as friction reduces its swing.由于摩擦减小摆动幅度，这个钟摆呈现阻尼振荡。
- forced oscillation
- 受迫振荡
- A forced oscillation occurs when an external force drives the system at its natural frequency.当外力以系统固有频率驱动时，就会产生受迫振荡。
- sustained oscillation
- 持续振荡
- The circuit can produce a sustained oscillation without any external input.该电路在没有外部输入的情况下也能产生持续振荡。
- oscillation amplitude
- 振荡幅度
- We measured the oscillation amplitude at different frequencies.我们在不同频率下测量了振荡幅度。
- oscillation frequency
- 振荡频率
- The oscillation frequency depends on the length of the pendulum.振荡频率取决于钟摆的长度。

Memory Tip
想象钟摆在 O 形轨迹上来回摆动——oscillation 就是这种‘振动、波动’的来回运动。
Context & Register
语域：mixed 常见场景：物理或工程等技术性讨论、正式书面语或演讲 oscillation 多用于物理、工程等专业领域，也常见于正式书面语；日常口语中通常较少使用，语气多属中性偏正式。
Pronunciation & Spelling
这些词都以 -ation 结尾，读作 /eɪʃən/，与 oscillation /ˌɑsəˈleɪʃən/ 的尾音押韵。注意拼写相似的 oscillate /ˈɑːsəleɪt/ 读音为 /eɪt/，与 /eɪʃən/ 不同。
