常见错误

❌ 错误:The rarefaction of water is common in deserts.
✓ 正确:The evaporation of water is common in deserts.

rarefaction 通常指气体或固体变得稀薄,不适用于液体;这里应使用 evaporation(蒸发)来描述水的减少。

❌ 错误:He felt rarefaction after running fast.
✓ 正确:He felt breathless after running fast.

rarefaction 是名词,描述状态或过程,不能直接用于描述人的感受;应使用 breathless(喘不过气)来表达呼吸困难的感觉。

近义词辨析

thinning

thinning 更通用,指任何东西变薄或变少,常用于日常语境;而 rarefaction 更专业,特指物质密度降低,多用于科学领域。

Thinning of hair is a common issue, while rarefaction of air is studied in meteorology.

dilution

dilution 强调通过添加溶剂使浓度降低,常用于化学或液体;rarefaction 则侧重于自然或物理过程中的密度减少,不涉及添加物。

Dilution of a solution reduces its strength, whereas rarefaction of gases occurs in vacuum chambers.
