水汽

Saturation vapour pressure; saturated water vapour pressure

一定的温度和气压下，湿空气达到饱和时的水汽压。

Correlation analysis showed that meteorological variables, such as containing water rate of sandland, photosynthetic available radiation, air temperature, saturated water vapour pressure difference, and physiological variables, such as leaf area index, leaf temperature, stomatal conductance, affected transpiration of S.

相关分析结果表明，环境因子，如沙地含水率、太阳有效辐射、大气温度和饱和水汽压差，以及植物因素，如叶面积指数、叶片温度和气孔导度等，均能显著影响沙柳的蒸腾作用。

This paper propounds an improved kinetic model of monthly potential evapotranspiration ETi:ETi=where i is a number of month, Pi the monthly mean atmospheric pressure,ti the monthly mean air temperature, di the number of days in a month,Ui the monthly mean wind velocity measured at height 10-12m, woi the saturated water vapour pressure at ti,and hi the monthly mean relative humidity.

本文提出了关于月可能蒸散量ETi动力学模型的改进形式：式中，i是月份的编号，Pi是月平均气压，ti是月平均气温，di是月的天数，Ui是在10─12m高度处观测的月平均风速，woi是在温度为ti时的饱和水汽压，而hi是月平均相对湿度。

In experimental respect, a set of fundamental framework to investigate the performance of the saturator has been designed, including the transparent saturator cylinder, the pressured air system, the distilled pressured water spray system, the precise measurement system of transient temperature and humidity variation. All the measurements are recorded using a computer-aided Data. Acquisition System .

利用该实验台，本文对该饱和器性能进行系统的实验，通过对大量的实验数据进行分析比较，得出饱和器内喷嘴的布置方案、水与空气的流动方式、水汽比、水温等因素对饱和器出口湿空气的温度及湿度的影响规律，通过实验结果与理论计算结果相比较，对饱和器的理论模型进行了验证。

Thus for sixteen days I saw from my window a hundred men at work like busy husbandmen, with teams and horses and apparently all the implements of farming, such a picture as we see on the first page of the almanac; and as often as I looked out I was reminded of the fable of the lark and the reapers, or the parable of the sower, and the like; and now they are all gone, and in thirty days more,probably, I shall look from the same window on the pure sea-green Walden water there, reflecting the clouds and the trees, and sending up its evaporations in solitude, and no traces will appear that a man has ever stood there.

所以一连十六天，我从我的窗口，看到一百个人，忙忙碌碌，像农夫一样地工作，成群结队，带着牲口和显然一应俱全的农具，这样的图画我们常常在历书的第一页上看到的；每次从窗口望出去，我常常想到云雀和收割者的寓言，或者那撒播者的譬喻，等等；现在，他们都走掉了，大约又过了三十天之后，我又从这同一窗口，眺望纯粹的海绿色的瓦尔登湖水了，它反映着云和树木，把它蒸发的水汽寂寥地送上天空，一点也看不出曾经有人站在它的上面。

Jiangnan is the first sign of the train, the window is rolling hills, mist-filled, green river flows slowly, water through mist, fog close to the River, along River Road, lingering fog, mountains are quiet and far-reaching, the water is clean and elegant, only 1 more along the mountain just far seen the mountains of trees, seems to disappear in a sea-green mist, the hill to the far extension of the water to spread , meeting in concert has a unique music, the air seemed to have music with a rhythm, beat, ups and downs, with a 1 wire 1 strand of water vapor, in the gradually dispersed inside ......

初见江南是在火车里，车窗外是连绵的小山，雾气缭绕，绿色的江水缓缓流动，水靠着雾，雾贴着江，江顺着路，大雾不散，山是宁静而深远的，水是清新而淡雅的，山只有1些大意罢了，远远望见山上的树，仿佛是一片绿海消失在雾霭中，山向远处延伸，水向那头漫延，交汇中演奏了一首无与伦比的名曲，空气中仿佛也含着音乐的节奏，跳动，起伏，含着1丝1缕的水汽，在车厢内渐渐地散去

And skewness of differences of temperature and water vapor depends on stability.

水汽差和温度差的偏斜度与稳定度有关，但是二氧化碳浓度的偏斜度还受到其它因素的影响。

Skewness of vapor flux is positive in stable and unstable BL.

水汽通量的偏斜度在稳定和不稳定条件下都是正的。

Since halfcentury, the international balloon meteorological sounding network has been carrying on the watervapor survey continuously.

半个世纪以来，国际性的气球探空网络一直在进行水汽探测。

White clouds of smoke and steam sand wich spaceshuttle Atlantis as it roars off Launch Pad 39A at NASA's Kennedy spaceCenter in Florida with its crew of seven for a rendezvous with NASA'sHubble Space Telescope.

肯尼迪航天中心，水汽、烟雾和沙子组成的白云伴随着亚特兰蒂斯号航天飞机咆哮着离开39A发射台，与它的7名乘员一起开始与哈勃望远镜约会之旅。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
