This has to do with the way a deep column of water boils.

When water is confined in tubes of very small bore, the forces of cohesion ( the attraction between water molecules) are so great that the strength of a column of water compares with the strength of a steel wire of the same diameter.

当水被限制在内径很小的管道中时，内聚压力（水分子之间的相互吸引力）是如此之大以致一支水柱的强度相当于一根直径相同的钢丝的强度。

In reality, such a column of water wouldn't be quite so high because here we're dealing with salt water, which is denser than fresh water.

实际上，这水柱的高度是最小的，因为我们现在讲的是海水，海水的密度大于淡水的密度。

Torricelli's work on water barometers showed that the pressure of the atmosphere could balance a column of water just over 30 feet in height.

托里切利在水银气压计方面的研究表明大气的压力可以让气压计中的水银柱上升30多英尺。

Let's accept that the pressure of one atmosphere is represented by the pressure of a column of water thirty-two feet high.

我们都承认，一个大气压力等于三十二英尺高的水柱压力。

Atmospheric pressure can support a column of water up to 10 meters high. But plants can move water much higher;

内聚压力理论大气压能够支持10米高的水柱，但植物可将水送得更高。

Atmospheric pressure can support a column of water up to 10 meters high.

大气压能够支持10米高的水柱，但植物可将水送得更高。
