vapor pressure

基本解釋

Where you measure the pressure, the vapor pressure, as a function of temperature.
在實(shí)驗(yàn)中你可以測量蒸汽壓，作為溫度的函數(shù)。
And then the vapor pressure of both substances above gets lowered. Anybody want to guess why they got lowered?
兩種物質(zhì)的蒸汽壓都會下降,有人猜一猜為什么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.
冰水混合物上方,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(diǎn),我們定義它為273。,水的三相點(diǎn),是一個(gè)特定的溫度和壓強(qiáng),可以使水的液態(tài)，氣態(tài)和固態(tài)三相共同達(dá)到平衡，三相點(diǎn)是液態(tài)。

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.
由于離子液體具有較低的熔點(diǎn)、良好的導(dǎo)電性和可以忽略的蒸汽壓等優(yōu)點(diǎn),引起了科學(xué)界和工業(yè)界的廣泛矚目。
蒸氣壓
It is shown that ionic liquid can reduce thesaturated vapor pressure of water.
結(jié)果顯示,離子液體能降低水的飽和蒸氣壓。

水分壓
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(xué)計(jì)算，一定溫度下提高水分壓可抑制WO_3的還原，當(dāng)還原溫度為400℃時(shí)，若P_(H20)／P_(H2)大于6.42時(shí)，WO_3的還原反應(yīng)將不能進(jìn)行。
