air isolation meaning in English

空气隔离
空气绝热
空气绝缘

The mechanical properties of the air cushion are studied theoretically . the fem air isolation model based on the state equation of ideal gas is used to study the effects of air isolation . the calculation results suggest that air isolation can reduce the hydrodynamic pressure significantly and restrain the dam vibrations during earthquake
应用在平面波作用下液体-气体-固体动力系统的理论，分析了大坝隔震气幕的力学性态；应用基于理想气体状态方程的气幕隔震的压力有限元模型，对模型气幕的隔震效果进行了研究。
The plane - wave analytic solution of the coupled fluid - air - solid system and the fem model of air cushion isolations are applied to study the influence of air cushion on earthquake response of dams . the calculations show that air isolation will reduce the hydrodynamic pressure significantly and restrain the dam vibrations during earthquakes . if the dam and reservoir is isolated by air cushions , it will decrease the hydrodynamic pressures by more than 90 % and the seismic stresses by 20 - 30 %
将本文首次提出的水体-气体-结构系统的平面波作用理论解和三维有限元模型，应用于溪洛渡双曲拱坝的抗震安全性和气幕隔震可行性研究中，表明气幕对高拱坝具有良好的隔震性能，可降低动水压力90以上，坝体地震拱应力20 30 ，减震效果显著，并使坝体的抗拉安全系数从0 . 93提高到3 . 58 。
