Bobby, from Billy's second dream, what is the equation  for absolute pressure at a depth in a fluid?

鲍比，来自比利的第二个梦，流体深度的绝对压力方程是什么？

But the actual pressure of the tire -- the absolute pressure -- is the atmospheric pressure, plus the gauge pressure.

但是轮胎的真实压力——绝对压力——是 大气压和大气压的总和。

Now, we can substitute the equation  for absolute pressure in for the pressure on the top and bottom sides of the cube in our net  force equation.

现在，我们可以用绝对压力方程代替净力方程中立方体顶部和底部的压力。
