采用不同原理的自动监测仪器在不同季节同时测定PM2?5与PM10，对所得数据中的 PM2?5与PM10“倒挂”现象进行分析。结果表明，当PM10采用振荡天平法时，PM2?5与PM10的“倒挂”率较高；冬季和夏季“倒挂”现象发生率明显高于其他季节；造成PM2?5与PM10“倒挂”的原因主要有监测过程中的随机误差，PM2?5与PM10的监测方法原理不同，监测方法之间存在显著差异等。
採用不同原理的自動鑑測儀器在不同季節同時測定PM2?5與PM10，對所得數據中的 PM2?5與PM10“倒掛”現象進行分析。結果錶明，噹PM10採用振盪天平法時，PM2?5與PM10的“倒掛”率較高；鼕季和夏季“倒掛”現象髮生率明顯高于其他季節；造成PM2?5與PM10“倒掛”的原因主要有鑑測過程中的隨機誤差，PM2?5與PM10的鑑測方法原理不同，鑑測方法之間存在顯著差異等。

Monitored PM using some different kinds of monitoring devices simultaneously in different seasons, analysised the revesal phenomenon between PM2?5 and PM10 , result showed that when use a tapered element oscillating microbalance( TEOM) device to monitor PM10 , could get more reverse data between PM2?5 and PM10 than using a beta attenuation monitor, in different seasons, the probability of reversal was higher in summer and winter. Analysed the monitoring principle and method about PM2?5 and PM10 ,and the structure of all kinds of monitoring instruments,we could come to the conclusion that the main reason cause the reversal between PM2?5 and PM10 , included that stochastic error, difference among all kinds of monitoring methods, and so on.
