摘　　要：为了分析取样时间与空气污染物浓度监测精度之间的影响关系,构建影响模型。从输入和输出两个方面,设置模型参数。针对气态和颗粒两种类型的空气污染物,模拟空气样本的采样与监测过程。在考虑环境因素的情况下,以污染扩散理论为支持,确定取样时间对污染物浓度监测精度的影响机理及影响参数取值,得出反映空气污染物浓度监测精度的模型输出结果。模型验证实验结果表明:设计模型输出的空气污染物浓度监测误差与实际监测误差之间的平均偏差均低于0.1 mg/m^(3),且影响模型的最大运行时间为1.2s,满足时效性要求。To analyze the relationship between sampling time and the accuracy of air pollutant concentration monitoring,an impact model is constructed by setting model parameters from both input and output perspectives.The study simulated the sampling and monitoring process of air samples for both gaseous and particulate air pollutants.Taking into account environmental factors,it is supported by the theory of pollution diffusion.The impact mechanism and parameter values of sampling time on the accuracy of pollutant concentration monitoring are determined,and the model output results reflecting the accuracy of air pollutant concentration monitoring are obtained.The model validation experiment results show that the average deviation between the designed model output air pollutant concentration monitoring error and the actual monitoring error is less than 0.1 mg/m^(3).The maximum running time that affects the model is 1.2 seconds,meeting the timeliness requirements.
