drop curtain

I'm almost sad to see the curtain drop on the final act.

我看到最后一幕的幕布落下几乎感到失落.

The mass transfer coefficient and drop of pressure in wet curtain are measured of counterflowing.

用气-水逆流接触法测定了湿帘中的传质系数和压降,得到关联式.

Then suddenly, when the Ant was almost ready to die of thirst, a large drop of water fell on it. And amid a glorious burst of music from the orchestra the curtain fell.

突然，就在蚂蚁要渴死的时候，一大滴水落了下来。乐队突然奏出一支雄壮的曲子，幕帘随之落下。

It will soon be time to drop the curtain upon this performance.

这个表演很快就要结束了.

While they're playing scene two in front of the curtain, we can drop in the scenery for the next act.

他们在幕前演第二场时，我们可以放下下一幕的布景。
