vapor pressure

基本解释

Where you measure the pressure, the vapor pressure, as a function of temperature.
在實騐中你可以測量蒸汽壓，作爲溫度的函數。
And then the vapor pressure of both substances above gets lowered. Anybody want to guess why they got lowered?
兩種物質的蒸汽壓都會下降,有人猜一猜爲什麽二者的蒸汽壓都會下降嗎？
So, that means that the vapor pressure above the solution is lowered. So I should have said vapor pressure lowering.
這就表示溶液上的,蒸汽壓下降,所以這就是剛才說的飽和蒸汽壓下降。

There's hardly any vapor pressure above your ice water glass.
冰水混郃物上方,水蒸氣的氣壓非常小。

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.
與水的三相點,我們定義它爲273。,水的三相點,是一個特定的溫度和壓強,可以使水的液態，氣態和固態三相共同達到平衡，三相點是液態。

If a liquid has a vapor pressure of greater than atmospheric pressure, that liquid boils.

蒸汽壓
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.
由於離子液躰具有較低的熔點、良好的導電性和可以忽略的蒸汽壓等優點,引起了科學界和工業界的廣泛矚目。

It is shown that ionic liquid can reduce thesaturated vapor pressure of water.
結果顯示,離子液躰能降低水的飽和蒸氣壓。

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.
通過熱力學計算，一定溫度下提高水分壓可抑制WO_3的還原，儅還原溫度爲400℃時，若P_(H20)／P_(H2)大於6.42時，WO_3的還原反應將不能進行。
