Undisturbed earths gravity field under the status of hydrostatic equilibrium is parallel gravity field, and its distribution of mass density is spherically Symmetric.
2
值得强调指出,在恒星大气中,流体静力平衡是非常精确地成立的。
A point worth emphasizing is that hydrostatic equilibrium is fulfilled with great accuracy in stellar atmosphere.
3
地球大气就处于地球引力和大气中气体压力共同作用之下的流体静力平衡状态。
The earth's atmosphere is in hydrostatic equilibrium under the combined action of the gravitational attractive force of the earth and the pressure of the gases in the atmosphere.
