  1. Abstract : through leaching test about pollutant from fly ash in different media, we get the conclusions of some pollutants. on the basis of the above, this paper gives two mathematical models of density change about pollutant from fly ash in underground water

    文摘:通過對不同介質條件下粉煤灰中污染離子的淋釋實驗，得出一些離子淋釋規律，在此基礎上，對粉煤灰中淋釋污染離子在地下水中的濃度變化從理論上給出兩種數學模型。
  2. The paper, by using the technology of gis and the method of systems engineering, analyzed the development situation of regional society and economy, the natural physical conditions, the situation of pollutant, and density distributing characteristics of pollutant, then set up the echoing relationship between pollute source diffusion and quality of air environment, which could make controlling index of pollution source discharging be closely linked with the quality of environment

    本研究採用gis技術，利用系統工程的方法根據區域社會經濟發展狀況、自然地理條件、污染源狀況及污染物濃度分佈特徵進行綜合分析研究，研究建立了污染源擴散與大氣環境質量的響應關系，將污染源排放控制指標與區域的環境質量直接掛鉤。
