大气污染物预测浓度有效数字的探讨

【摘要】 通过对大气污染物预测值(叠加值)的有效数字及相关参数的探讨,得出大气污染物(SO2、TSP、PM10、NO2)预测浓度最终的有效数字为2位。考虑实际计算需要,建议大气污染物预测浓度以mg/m3为单位,小数点后最多保留3位数字。更多还原

【Abstract】 Through the discussion of predicted air pollutant concentrations (value overlap) and its associated parameters, the conclusion is given that significant digits should be two digits at least for making use of air pollutant concentration values (SO2、TSP、PM10 、NO2). In consideration of actual need, it is desirable to take mg/m3 as basic dimension, maintaining 3 digits at most after decimal point.更多还原
