TSP日平均浓度监测采样时间有效性研究

The Validity Research of the Sampling Time on Monitoring Total Suspended Particulate's Daily Average Density

通过对诸暨市城区空气中总悬浮颗粒物 (TSP)采用不同的自动连续采样时间获得的日平均浓度对比研究发现 :每日采样时间只有达到 1 8h以上时 ,才能体现真实的日平均浓度。

The investigations on total suspended particulate in Zhuji with different automatic continued sampling obtained its daily average density.Sampling time must more than eighteen hours in order to get the true outcome according to the research result.
