在初中物理旧课本第一册129页,“活塞式抽水机和离心式抽水机”的开头有这样一段课文:“抽水机也叫水泵,用来把水从低处抽到高处,它是利用大气压来抽水的.”在新编初中物理课本第一册134页,“活塞式抽水机”的开头也有更为明确的一段课文:“抽水机也叫水泵,是利用大气压把水从低处抽到高处去的.”(以下简称“课文”)由此导致了近几年在有的地区,编出了这样的中考题或练习题:“抽水机又叫水泵,它是利用
On the 129th page of the old textbook of junior middle school physics, the beginning of the “piston-type pump and centrifugal pump” was: “The pump is also called a water pump and it is used to pump water from a low place to a high place. It uses atmospheric pressure. Pumping water.“ In the new book 134 of the junior middle school physics textbook, the beginning of the ”piston pump“ also has a more clear section of text: ”The pump is also called a water pump. It uses atmospheric pressure to pump water from a low place to a high place.“ The ”.“ (hereinafter referred to as ”text“) has led to the preparation of such an examination or exercise in some areas in recent years: ”The pump is also called a water pump. It is used.
