1、nitrogen pollution of Changhun groundwater analysis, the discovery showed the main nitrogen pollutant in the groundwater is nitrate.───对长春市地下水中“三氮”污染状况的分析,发现硝酸盐是地下水中的主要氮污染物。
2、results from investigating and evaluating groundwater pollutant sources indicated that waste landfill was one of main pollutant sources.───地下水污染源调查评价研究表明,垃圾填埋堆放场是造成地下水污染的主要污染源之一。
3、The finite difference method is used to solve the coupling model, and the influence of starting pressure gradient on the distribution of groundwater pollutant concentrations is analyzed.───采用有限差分法和混合有限分析法对耦合模型进行数值求解,并分析了启动压力梯度对地下水污染浓度的影响。
