| 释义 | hydrostatic adjective physics specializeduk /ˌhaɪ.drəʊˈstæt.ɪk/ us /ˌhaɪ.droʊˈstæt̬.ɪk/ relating to fluids (= liquids or gases) that are not in motion: 流体静力的，水静力的 Hydrostatic pressure pushes water through the rock.流体静压推动水通过岩石。 In a hydrostatic test, the pipes are filled with water and put under pressure to check for leaks.在流体静压试验中，管道中充满水，并在压力下检查是否有漏水的情况。 Examples of hydrostatichydrostatic These surfaces are distorted by hydrostatic balance toward negative anomalies of pressure produced by the bend of the low-pressure vortex cores. In such static solutions the hydrostatic pressure in the fluid and the elastic pressure exerted by the walls of the crack are in balance. The use of the condition of equilibrium between the ponderomotive and hydrostatic forces is necessary to obtain the power threshold to produce self-focusing. We initially input turbulent velocity into the magnetized plate-shaped cloud which is in hydrostatic equilibrium between thermal pressure and self-gravity. Besides arithmetical works, he wrote a treatise consisting in a collection of problems about weighing with hydrostatic a and normal balances. The hydrostatic approximation leads to an underestimation of both the maximum growth rate and the wavenumber at which it occurs. A representative example is shown in figure 3(b) (hydrostatic approximation: dotted line). In a homogeneous fluid at rest, ver tical momentum conservation requires that the fluid be in hydrostatic balance. Thus, any departure from hydrostatic balance gives rise to flow, with effectively immediate adjustment of velocity profile across the narrow gap. The next step in analysing large-scale flow is to show that it is hydrostatic. As the top of the cavity moves further away from the probes, the pressure returns to the local hydrostatic value. Further, we assume that the waves are sufficiently long for the hydrostatic equation to be valid. The flow remains hydrostatic and departs from geostrophic only in the first equation of motion. The pressure is also observed to return to the local hydrostatic value with less overshoot. The pressure signals of figure 2 have been superimposed on each other (taking into account the difference in hydrostatic pressure) and are shown in part.
