全球年发污染物annual global emissions
在发污染物附近nearby emitter
废气扩waste gas dispersion The process of breaking up and producing a diffuse distribution of the unusable aeriform fluid or suspension of fine particles in air resulting from a manufacturing process or the burning of a substance in an enclosed area (对制造生产过程或在一个封闭区域内物质的燃烧而排放的无法使用的气状流体、或空气中的悬浮微粒进行分解,和产生扩散分布的过程。)
dispersion A distribution of finely divided particles in a medium (细小分离粒子在介质中的分布。)
diffusion The spontaneous movement and scattering of particles (atoms and molecules), of liquid, gases, and solids (液体、气体和固体颗粒(原子和分子)的自发性移动与分散现象。)
污染diffuse pollution Pollution from widespread activities with no one discrete source, e.g. acid rain, pesticides, urban run-off etc. (由非单一原因的广泛活动造成的污染。例如酸雨、农药、城市下水堵塞等。)
diffuse source Pollution which arises from various activities with no discrete source (从非离散来源的各种活动产生的污染物。)
计算dispersion calculation The calculation of pollutant dispersion is based on the use of air dispersion models that mathematically simulate atmospheric conditions and behaviour. Dispersion models can provide concentration or deposition estimates and can be used to evaluate both existing and hypothetical emissions scenarios (污染扩散的计算是基于空气扩散模型通过数学方法来模拟大气条件和行为;扩散模型可以估计污染物的浓度或沉降量,同时可以评估现有或假设的排放情形。)
distribution In an environmental context, the term refers to the dispersion of air pollutants and depends on the type of pollution source (point source, line source, diffuse source), the wind velocity and the wind direction. Distribution can be active or passive (在环境领域,这个词用来表达空气污染物的散布并且与污染源的种类(点声源、线污染源、混合污染源)、风速和风向相关。散布可以是主动的,也可以是被动的。)
污染物扩pollutant dispersion The spreading of pollutants from a point of release in air, soil and water. The dispersion of air pollutants is heavily influenced by how and where the pollutant is emitted, e.g., by continuous low-level versus accidental releases, multiple stacks versus a few, or the height of the stacks. The nature of the local terrain meteorology and the chemistry of the released material strongly influence the pattern of regional and, finally, global dispersion and transport (污染物通过传播释放到空气、土壤和水中。空气污染物扩散的问题是在哪里及如何处理污染物的排放,例如通过连续的少量的释放,或多重叠加的释放。局部地形气象学和化学物质属性会强烈影响释放的模式。最后,污染物扩散涉及到区域和全球的分散性和运输。)

evapotranspiration Discharge of water from the earth's surface to the atmosphere by evaporation from lakes, streams and soil surfaces and by transpiration from plants. Also known as fly-off (水从地球表面通过蒸发,排放进入大气。来源于湖泊,河流和土壤表面以及植物的蒸腾作用。)
