Something that settles to the bottom of a fluid; sediment.
沉渣沉到液体底部的东西; 沉积物
As soon as the sediment starts creeping up the shoulder of the bottle, stop pouring. You should now have a glass of star-bright beer with a head(of foam) that stands proud of the glass but does not overflow.
啤酒瓶底的沉淀物一到瓶颈部位, 就不要往外倒啤酒了。此时你的一杯啤酒会金灿灿地发亮, 酒泡鼓出酒杯口, 而又不会溢出杯外。
He emptied out the water barrel to clear it of sediment.
他把水桶倒空以清掉桶底的沉淀物。
