在酒店里,常需把大缸里的酒移装到小坛里,如果直接往小坛里倒,因为大缸笨重,坛口又小,容易把酒倒到外边,很不方便.人们在实践中想出一个好办法:找一根软橡皮管,先把管子的一头插在酒缸里,用嘴在另一头稍稍一吸,再把它插入坛里,只要小坛放在酒缸的液面下,酒便自动从管子里流进坛内.人们把这种神奇的弯管叫“过山龙”,物理学上叫它“虹吸管”,这种有趣的现象,就叫做“虹吸现象”.
In a hotel, it is often necessary to transfer the wine from the large tank to a small altar. If you go directly to a small altar, because the large cylinder is bulky and the mouth of the altar is small, it is easy to pour the wine out. It is inconvenient. People are practicing I thought of a good idea: find a soft rubber tube, put one end of the tube in the jar, and then use the mouth to suck it slightly on the other end, and then insert it into the altar as long as the little altar is in the liquor Under the surface, the wine automatically flows from the tube into the altar. People call this magical elbow a “crossing dragon” and physics call it a “siphon”. This interesting phenomenon is called “siphoning”. .
