初二《物理》课本第五章《连通器》一节,在实验举例方面不具一般化。其中p.116图5—28与p.117图5—29均是很好的连通器实例,只不过特殊。所谓连通器,就是底部相互连通的容器。按其含义,则图1理当是一连通器例子,各容器不象课本上那样全开口。因而,关于书上所说的,“当连通器里只有一种液体时,在液体不流动的情况下,各容器中的液面总保持相平”这一结论,对于图1将无法解释。另外,p.120练习五第(1)题,如果表示含水层的A、B两处地处高山,喷泉口在山脚,虽为连通器,但山顶与山脚大气压不等,加之由于重力作用,泉水不可能如图所示那样喷至与A、B同一 The fifth chapter of the “Physics” textbook, “Connectors”, is not generalized in terms of experimental examples. Among them, Figure 5-28 of p.116 and Figure 5-29 of p.117 are examples of good communicators, but they are special. The so-called communicators are containers that communicate with each other at the bottom. According to its meaning, Figure 1 is an example of a communicator. Each container does not open as a textbook. Therefore, as far as the book says, “when there is only one liquid in a connected vessel, the liquid level in each vessel remains flat under the condition that the liquid does not flow,” this conclusion cannot be explained with respect to FIG. In addition, in p.120 exercise five (1), if the aquifers A and B are located in high mountains, the mouth of the fountain is at the foot of the mountain. Although it is a connected vessel, the atmospheric pressure at the top of the mountain and the foot of the mountain is not equal, and due to gravity, Spring water cannot be sprayed as it is with A and B
