vapor pressure

基本解释

Where you measure the pressure, the vapor pressure, as a function of temperature.
在实验中你可以测量蒸汽压，作为温度的函数。
And then the vapor pressure of both substances above gets lowered. Anybody want to guess why they got lowered?
两种物质的蒸汽压都会下降,有人猜一猜为什么二者的蒸汽压都会下降吗？
So, that means that the vapor pressure above the solution is lowered. So I should have said vapor pressure lowering.
这就表示溶液上的,蒸汽压下降,所以这就是刚才说的饱和蒸汽压下降。

There's hardly any vapor pressure above your ice water glass.
冰水混合物上方,水蒸气的气压非常小。

And the triple point of water is 16K that temperature and pressure - there's a unique temperature and pressure where water exists in equilibrium between the liquid phase, the vapor phase, and the solid phase.
与水的三相点,我们定义它为273。,水的三相点,是一个特定的温度和压强,可以使水的液态，气态和固态三相共同达到平衡，三相点是液态。

蒸汽压
The ionic liquids(ILs) thanks to their low melting point,high conductivity and negligible vapor pressure have been attracting great attention of the academic and industrial circles.
由于离子液体具有较低的熔点、良好的导电性和可以忽略的蒸汽压等优点,引起了科学界和工业界的广泛瞩目。
蒸气压
It is shown that ionic liquid can reduce thesaturated vapor pressure of water.
结果显示,离子液体能降低水的饱和蒸气压。

According to the calculation of thermodynamics, at certain temperature,increasing vapor pressure (P_(H2O)/P_(H2)) can effectively restrain the deoxidized ofWO_3. When the temperature is 400℃, if the value of P_(H2O)/P_(H2) is over 6.42, thedeoxidized reaction of WO_3 can't carry on.
通过热力学计算，一定温度下提高水分压可抑制WO_3的还原，当还原温度为400℃时，若P_(H20)／P_(H2)大于6.42时，WO_3的还原反应将不能进行。
