Comparison of Two Analysis Methods of Fugitive Road Dust Size in Shanghai City(Chinese)
-
摘要: 对54个上海城市地表扬尘样品进行激光法与动力学粒径谱仪法的粒径分析结果作了相关比较.拟合结果表明，在缺少空气动力学粒径谱仪的情况下，可以通过回归方程式建立激光粒度仪和动力学粒径谱仪测试结果之间的关系，从而获得研究所需的动力学粒径对应的质量百分比含量.两种仪器测试所得数据的转换结果具有统计学的意义.由于两种方法的原理不同，结果的差异还可为源解析提供进一步分析的线索.Abstract: This paper reported the comparison analysis between laser method and aerodynamic particle sizer spectrometer method of particle size measurement for dust samples of 54 roads form Shanghai city center.Regression relations were established between the results by two methods.The difference of results was explained by their testing principles,which imply more informations for further work.
