深度是指在连通的同种液体里，最高自由液面到某处的垂直距离．如能正确灵活地运用这一概念，就会给解题带来极大的方便例1问图1里的油罐木塞A处的深度是那一段？解由深度概念可知，A所在的深度是图中的h，而不HAed例2在图1中，静止浮物下的A点与水中的B点在同一水平面上，试比 Depth refers to the vertical distance from the highest free surface to a certain point in a connected liquid of the same kind. If this concept can be used correctly and flexibly, it will bring great convenience to solving the problem. Example 1 What is the depth of the fuel tank stopper A in Figure 1? The solution can be seen from the concept of depth. The depth at which A lies is h in the graph, not HAed Example 2 In Figure 1, the point A below the stationary float is on the same level as the point B in the water.
