The vapour cone effect is caused by pressure differences around the aircraft. A sudden drop in pressure associated with high speed allows water vapour, which is normally invisible, to condense as fog.
蒸汽锥效应是由于战斗机周围的压力差所导致的，高速飞行时压力的陡然降低会使不可见的水蒸气凝结成雾气。
This is important because a high pressure drop would mean that more energy is required to drive the vapour up the distillation column.
这一点很重要，因为如果压力下降太大，就意味着需要更多能量来推动蒸气上升。
High water saturated vapour pressure leads to the more possible occurrence of cavitation phenomena in water hydraulic pump, and so as in sliding shoes hydraulic supporting without exception.
水的高饱和蒸汽压力使得水压泵中极易发生气蚀现象，滑靴静压支承也不例外。
High strength prestressed heat barrier pipe is used as a thermal insulating pipe to carry high temperature and pressure vapour into underground for crude oil exploitation.
材质为高强钢的预应力隔热管是在石油开采中用于地下输送高温高压水蒸汽的绝热管。
