pressure in bubbles

Cavitation is a weeny gas bubbles ( or called gas nucleus) suddenly growing phenomenon, which arosed by local low pressure ( lower than saturated steam pressure at the same temperature) in the liquid.

空化是由于液体中的局部低压（低于相应温度下该液体的饱和蒸汽压）使液体汽化而引发的微气泡（或称气核）爆发性生长现象。

On the basis of the practical data tested, the characteristics and law of water hammer wave, secondary bubbles impluse, vibration water pressure in site, bank vibration and vibration of structures in water when blasted under limited waters are analyzed, some viewpoints are put forward.

依据实测数据分析了有限水域水下爆破的水击波、二次气泡脉动、爆破地震动水压力、岸坡震动及水中建筑物震动的特征和规律，并提出了一些看法。

When the external pressure reduces, bubbles form in the blood, leading to lung damage within minutes.

当外部压力降低, 血液中形成气泡, 肺部会在几分钟内受损.
