Memory Tip
把“magni”（大）和“-fication”（使…化）连起来：用放大镜看小字，magnification 就是“放大”这件事或“放大率”。
Context & Register
语域：neutral 常见场景：光学仪器使用、科学课堂讲解、摄影与图像处理 magnification 通常指通过透镜或光学设备使物体在视觉上变大，也可泛指扩大这一行为；多用于科技、教学或产品说明等场合，语气比较中性，在一般说明和正式书面语中都自然。
Pronunciation & Spelling
这些词都以 -ification 结尾，重音均落在 /keɪ/ 上，因此与 magnification 押韵（/ˈkeɪʃən/）。注意 magnify /ˈmæɡnɪfaɪ/ 和 magnificent /mæɡˈnɪfɪsənt/ 拼写相近，但发音完全不同，不押韵；另外 -ation 结尾的词（如 application /ˌæplɪˈkeɪʃən/）虽然也押韵，但拼写部分不是 -ification。
