【摘要】：為考察光散射法和β射線衰減-光散射聯(lián)用法的適用性,以β射線衰減法顆粒物自動監(jiān)測儀(BAM)為標準,于2016年2月4日—4月18日,在中國環(huán)境科學研究院利用β射線衰減-光散射聯(lián)用法顆粒物自動監(jiān)測儀(MP-CPM)與光散射法傳感器對ρ(PM_(10))和ρ(PM_(2.5))測量結(jié)果進行了對比.結(jié)果表明:(1)MP-CPM與BAM測量ρ(PM_(10))的結(jié)果具有較好的一致性,相關系數(shù)為0.92,平均相對偏差為0.04%;ρ(PM_(2.5))結(jié)果一致性較差,相關系數(shù)為0.69,MP-CPM測量ρ(PM_(2.5))整體較高于BAM,平均相對偏差為45.8%.(2)光散射法傳感器與BAM測量ρ(PM_(2.5))結(jié)果一致性較好,相關系數(shù)為0.85,平均相對偏差為11.24%,但ρ(PM_(10))遠低于BAM,平均相對偏差為-44.64%.在特殊污染情景下,光散射法將因受到較大影響而嚴重錯估顆粒物濃度.煙花燃放期間,MP-CPM和光散射法傳感器嚴重低估顆粒物濃度,與BAM測量顆粒物濃度的平均相對偏差均低于-50%;沙塵污染過程中,MP-CPM嚴重高估ρ(PM_(2.5)),與BAM測量ρ(PM_(2.5))結(jié)果平均相對偏差為79.27%,光散射法傳感器嚴重低估ρ(PM_(10)),與BAM測量ρ(PM_(10))結(jié)果平均相對偏差為-59.35%.研究顯示,不同原理的儀器,在不同的使用場景下應該區(qū)別對待.
[Abstract]:In order to investigate the applicability of the light scattering method and the 尾 ray attenuation-light scattering method, using the 尾 ray attenuation method as the standard for the automatic monitor of particulate matter (BAM), from February 4 to April 18, 2016, In this paper, the results of 尾 -ray attenuation-light scattering automatic particle monitoring instrument (MP-CPM) and light scattering sensor are compared with those measured by 蟻 _ (P) PMSP _ (10) and 蟻 ~ (+) _ (PMSP) _ (2.5) at the China Institute of Environmental Sciences. The results showed that the results of MP-CPM and BAM were in good agreement with those of BAM. The correlation coefficient was 0.92 and the average relative deviation was 0.04. The correlation coefficient is 0.69mP-CPM, the average relative deviation is 45.80.The correlation coefficient is 0.85 and the average relative deviation is -44.640.The correlation coefficient is 0.85, the average relative deviation is 11.24, but the average relative deviation of 蟻 PMP-CPM is far lower than that of BAM.The average relative deviation is -44.640.The correlation coefficient is 0.85, and the average relative deviation is 11.240.The average relative deviation is -44.640.The correlation coefficient is 0.85 and the average relative deviation is 11.24. Under the special pollution scenario, the light scattering method will seriously misestimate the concentration of particulate matter due to its great influence. MP-CPM and light scattering sensors seriously underestimated the concentration of particulate matter during fireworks discharge. The average relative deviation with BAM was lower than -50, and the average relative deviation between MP-CPM and BAM was 79.270.The average relative deviation between MP-CPM and BAM was -59.350.The average relative deviation between MP-CPM and BAM was -59.35. Research shows that instruments with different principles should be treated differently in different usage scenarios.
