| 摘 要： | 环境空气SO2采样由每天采样3次,每次采样30分钟的瞬时采样变成24小时的连续采样,其测定浓度都降低了。其原因主要有,监测点位重新布设后,有些采样点位向郊区转移、进气管接胶管采样、进气管有水、采样流量变小及延迟化验分析等,都影响采样结果。

| Abstract: | The gas SO2 in the air is sampled three times every day.During the process thirty minutes instantaneous sampling changes to twenty-four hour＇s continuous sampling.Then the determination of the concentration of SO2 is both reduced.The main reasons are as follows.After the monitoring points are relaid,some sampling point positions move into the suburbs.Intake manifold is connected to the hose to sample.There is water in the intake manifold.Sampling flow rate becomes smaller.Laboratory analysis is delayed.All the above-mentioned factors have an effect on the sampling results. |
