Methods Sampling of 33 specimens from surface water, groundwater and spring water, do microbiological and metal element (iron, manganese) tests.───方法采集地表水、地下水、山泉水样本33份,进行微生物学检验及铁、锰等金属元素检测。
Analysis of groundwater sampling from 1998 to 2002 indicates that the mineralization degree of groundwater varies both temporally and spatially in this area.───地下水样品的分析,得出该地区地下水矿化度在时间与空间上皆存在明显的变异性。
Together with MicroPurge controllers, flow cells, and accessories, they create the most reliable, cost-effective low-flow groundwater sampling system available.───装有控制器、流量元件和配件,使系统能够进行最可靠的低成本低流量地下水取样。
