【摘要】 使用由美国R&P公司生产的Automatic Cartridge Collection Unit,即自动滤膜采集单元,简称ACCU单元,可进行设定条件下(如风向、时间、浓度等)的颗粒物采样,并对颗粒物质量浓度和有关元素的浓度进行分析,它不但能测定颗粒物和有关元素的浓度水平,还能判定有关条件下的浓度分布。使用实践证明,该单元可为环境监测和治理提供有力和方便的手段。更多还原

【Abstract】 The Automatic Cartridge Collection Unit (ACCU) produced by R&P corp. can be used for particulate collecting by setting different conditions for example wind direction, time,concentration,etc. Not only mass concentration of particulate and other elements in samples but also concentration distribution of some conditions can be analyzed. It can be a good and convenient method for environmental monitoring and environmental management by using of this unit.更多还原
