The ground effective radiations are calculated based on the ground temperature. air temperature. water vapour pressure and total cloud cover.
再利用地面温度、气温、水汽压和总云量,计算得出福建省各地的地面有效辐射的月、年平均辐照度。
More specifically, we can say that there is a trend towards equilibrium between the water vapour pressure in the product and the partial pressure of the water vapour in the air.
我们可更准确地说,是产品内部的水蒸汽压力与空气中部分的的水蒸汽压力之间有一种趋于平衡的趋势。
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。
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。
Percentage ration of the actual vapour pressure in the air to the saturation vapour pressure with respect to water at the same temperature and pressure.
空气中的实际水气压与在相同温度和气压下的水面饱和水气压的百分比。
Under a constant atmospheric pressure, why decrease in air temperature will lead to decrease in water vapour holding capacity, and thus, increasing its relative himidity(RH)?
为甚麽在空气压力不变情况下,气温下降会使空气盛载水气的能力下降?。
The apparatus also generates distilled water includes low pressure waste energy separator, heated separator and vapour compressor combing to the compelling circle-loop.
该设备包括与强制循环回路相结合的低压废能分离器、加热分离器和蒸汽压缩机以产生蒸馏水。
