urban pollutant 中文意思是什麼
urban pollutant
解釋
城市污染物-
Field observations and physical models may be used to investigate pollutant transportation and dispersion within urban canyons and validate numerical models. on the other hand, validated numerical models are often applied to simulate in detail atmospheric dispersion within the urban canopy. the numerical results in combination with physical model and or field data may be used to assess urban air quality and support decisionmaking for pollution control strategies and traffic planning
外場觀測和物理模擬可以考察街谷內污染物的傳輸擴散規律並對數值模式進行檢驗，另外，復雜的數值模式則可對城市冠層內大氣擴散問題進行詳細模擬，數值模擬和外場觀測及物理模擬相配合，可用於環境質量評價污染控制決策及交通規劃。 -

The data collected at the station in 2003 show an upward trend of air pollutant concentrations similar to that recorded at the general air quality monitoring station in kwai chung, a district with land use ( an urban area with mixed residential, commercial and industrial developments ) similar to that in kwun tong. therefore, the upward trend of ambient air pollution is not a localised phenomenon peculiar to a particular district
（二）及（三）位於觀塘區的空氣監測站，屬於一般空氣監測站，其於2003年所收集得的數據，跟位於土地用途相若地區的葵涌監測站所錄得的空氣污染物濃度均有上升趨勢，所以這不是一個局部地區現象。 -

Calculational and distributive method of urban total permitted air pollutant emission
城市大氣污染物允許排放總量計算與分配方法研究 -
Sulfur dioxide ( so2 ), a common pollutant of urban air, can severely produce toxic symptoms in both humans and animals. it can cause respiratory tract diseases such as tracheitis, asthma, emphysema, and has close relations with lung cancer
二氧化硫（ sulfurdioxide ， so _ 2 ）是一種常見的對人體健康危害較大的大氣污染物，可引起氣管炎、哮喘、肺氣腫等多種呼吸道疾病，甚至與肺癌的發生有關。 -
