沉淀 | precipitation The process of producing a separable solid phase within a liquid medium; represents the formation of a new condensed phase, such as a vapour or gas condensing to liquid droplets; a new solid phase gradually precipitates within a solid alloy as a result of slow, inner chemical reaction; in analytical chemistry, precipitation is used to separate a solid phase in an aqueous solution; chemical (在液体培养基内产生可分离的固体相的过程;代表着新的凝聚相的形成,如蒸汽冷凝液液滴或气体。有一种新的固体相通过逐步沉淀形成坚实的合金,这是一个缓慢的化学反应过程;在分析化学中,沉淀用于分离水溶液中的固体相。) |
