That rise is displaced salt water.

这个高度，是盐水的代替。

When Archimedes climbed in and out of the bath, he carefully studied the displaced water.

当阿基米德在浴缸爬进爬出，他仔细研究了排出的水。

We chose concrete because it's heavy and displaces water, based on Archimedes' principle.

基于阿基米德的原理，我们选择了混凝土，因为它很重，可以排水。

In turn, a buoyant force equal to the weight of the displaced water pushes up, counteracting you and your board's weight.

这会产生一股向上推的浮力，其力量大小等同于被排开水的重量，可以抵消你和冲浪板的重量。

And when the crew wants to rise, they force air into the tank to displace the water, making it lighter.

当船员们想要上升时，他们会迫使空气进入水箱以取代水，使水箱变得更轻。

This meant that the displaced water measured his volume exactly.

这意味着被置换的水准确地测量了他的体积。

The wind and low pressure system can also displace water elsewhere, causing a reverse storm surge on the opposite side of the hurricane.

风和低压系统还可以将水转移到其他地方，从而在飓风的另一侧造成反向风暴潮。

This energy travels up to the surface, displacing water and raising it above the normal sea level, but gravity pulls it back down, which makes the energy ripple outwards horizontally.

这能量向上行进到表面，排开水且使水面高于正常的海平面，但重力把它拉下来，使得能量向外横向传播。

Unlike a regular tsunami that is created by an earthquake, a mega-tsunami is usually created when a massive amount of material suddenly falls into water, which displaces that water into a huge wave.

与一般由地震引发的海啸不同的是，超级海啸通常是由大量物质突然落入水中而引起的，从而激起巨大的海浪。
