延缓

• ピンイン: yán huǎn

意味

（進行を）遅らせる／緩める

Implies slowing or deferring something rather than stopping it entirely. Common in medical contexts (延缓病情 = slow disease progression), health discourse (延缓老化 = slow aging), and policy management (延缓实施 = defer implementation). Distinguishes from 延误 (unintentional or harmful delay) and 延迟 (neutral postponement) by its purposeful, managing quality.
