一、简单的虹吸现象我们先看一个简单的实验,如图1所示,一根软管充满水,B端放入装有水的容器中,这时水能通过导管从液面较高的容器中不断从A端流出,这种现象叫做虹吸现象。虹吸现象是怎么产生的呢?可以作如下简单分析。在液面上取一点C,在管中取一点与液面等高的D点,设大气压为 First, a simple siphon phenomenon We first look at a simple experiment, as shown in Figure 1, a hose filled with water, B end into the container filled with water, then water through the catheter from the higher liquid level Container A continuously from the outflow, this phenomenon is called siphon phenomenon. Siphon phenomenon is how to produce it? Can make the following simple analysis. In the liquid to take a little C, take a little in the tube and the liquid level D point, set the atmospheric pressure
