vapor n.〔美國〕= vapour.

The “supersaturation ratio“ is the ratio of the excess vapor density to the saturation value . “過飽和比”是超過飽和值的蒸汽密度與飽和值的比。

“ fog , mist “ haze are all water vapor at ground level and above . “fog,mist,haze”均為地面及地面以上的水蒸氣。

If a bottle of ether is opened at one end of a room, we can soon smell the vapors at the other end . 假如在房間的一端打開一個乙醚瓶,在房間的另一端就可立刻聞到乙醚蒸氣的味道。

The vapor pressure and heat of vaporization have been shown to be significant properties in nonsteady droplet vaporization . 在非穩態的液滴汽化中,蒸氣壓和汽化熱是重要的性質。

Fumes or vapor are given off from storage tanks, processing vats and other types of processing equipment . 從貯罐、工藝加工用槽或其他類型工藝加工設備散出煙霧或蒸氣。

The enclosed space contains air, water vapor, and sufficient excess water so that the vapor is saturated . 封閉容器的空間內儲有空氣、水蒸汽和足夠的使水蒸汽飽和的水。

The temperature at which the water vapor in a given sample of air becomes saturated is called the dew point . 使一已知空氣樣品中的水蒸汽達到飽和時的溫度稱為露點。

The addition should be interrupted when brownish vapors are liberated to avoid excessively vigorous reaction . 當有棕色蒸氣析出時,加料要中斷,以免反應過分激烈。

One canister handles the fuel tank vapors, and the other handles the carburetor float-bowl vapors . 一個活性炭罐控制燃油箱的蒸汽,另一個控制化油器浮子石的蒸汽。

As the air passes down through the canister, the gasoline vapor is trapped by the charcoal particles . 當這些空氣向下流過活性炭罐時,汽油蒸氣被活性炭粒子吸附。

The physical and chemical interactions among the particles, gases and vapors are incredibly complex . 顆粒物、氣體和蒸汽之間的物理反應和化學反應是極為復雜的。

The vapor passes through the control line and into the canister, where it is absorbed by the charcoal . 蒸氣通過控制管路進入活性炭罐,并被罐里的活性炭吸收。

In effect, air may be regarded as a sort of sponge, filled more or less completely with water vapor . 事實上,空氣可被看作是一塊海綿,或多或少地含有水汽。

The vapor from the upper container is condensed, the condensate is collected and its volume measured . 上面容器中的蒸氣冷凝,將凝結液集中并測量其體積。

The presence of a nonvolatile solute in a liquid always lowers the vapor pressure of the solution . 溶液中存在的非揮發性溶質,總是使溶液的蒸氣壓降低。

Although water is essentially transparent, water vapor appears white as does ground glass . 雖然水基本上是透明的,但是水蒸汽則呈白色,像毛玻璃一樣。

If water is not changed to vapor and removed from the crankcase, it can cause serious trouble . 如果水不變成蒸氣并排出曲輔箱,它將導致嚴重故障。

The “supersaturation ratio“ is the ratio of the excess vapor density to the saturation value . “過飽和比”是超過飽和值的蒸汽密度與飽和值的比。

We get the maximum enrichment in it by taking just the first bit of vapor that comes off . 取剛剛離開的第一點蒸氣,可得到它的最大富集濃度。
