在生活实践中如图1所示少量的水放入细管中竞能把连接的木桶 A 压坏;如图2所示航行在海上两艘船平行前进的时候,两船相吸,出现过许多次撞船事故如图3喷雾器怎样工作的等等现象应如何来解释. In life practice, as shown in Fig. 1, a small amount of water is put into the straw to crush the connected cask A; as shown in Figure 2, when the two ships on the sea advance in parallel, the two ships attract each other and appear. How many times a ship collision accident occurred, such as how the sprayer works, should be explained.
