The bubbles are hydrostaticforce-fields that contain breathable atmospheres for the city's inhabitants.
一个气泡就是一个静水力场，其中充满了供城市居民呼吸的空气。

And since a typical tower contains a full day's worth of water, the force of gravity can maintain the hydrostatic pressure of the water system even when the power goes out.
普通水塔储蓄一整天的用水，由此，即便在停电的情况下，重力作用仍能保持供水系统的静水压力。

The action forces applied on rock mass of equivalent continuum by seepage include two parts, i. e., hydrostatic seepage pressure and hydrodynamic seepage pressure (seepage body force).
