用法
- To restore something to its original state - 把现场还原 (bǎ xiànchǎng huányuán) to reconstruct the scene, 数据还原 (shùjù huányuán) to restore data.
- Note the reading is huán (to return), not hái; 还 as "to return/give back" drives the meaning.
- Also the chemistry term reduction (opposite of 氧化 oxidation) - 氧化反应 (yǎnghuà fǎnyìng) an oxidation reaction.
