Coarsening

释义 Definition

coarsening：变粗；变得更粗糙/更不精细；在材料科学、图像处理等语境中也常指粗化过程（例如晶粒变大、结构尺度变大、分辨率降低等）。（另有较少见用法可指语言或行为“变粗俗”。）

发音 Pronunciation (IPA)

/krsn/

例句 Examples

The fabric is coarsening after too many washes.
这块布洗了太多次后变得更粗糙了。

In high-temperature treatment, coarsening of the microstructure can reduce the material’s strength over time.
在高温处理过程中，微观结构的粗化可能会随着时间推移降低材料强度。

词源 Etymology

来自形容词 coarse（“粗糙的、粗的”）加动词后缀 -en（表示“使变得……”）构成 coarsen（“使变粗/变粗”），再加 -ing 形成名词/动名词 coarsening，表示“变粗的过程/粗化”。
