室内空气负离子浓度与PM2.5、PM10浓度的关系

摘要

2013年11月，在室内对空气正、负离子浓度、PM10（可吸入颗粒物）、PM2.5（细颗粒物）等进行测量，将测量数据用SPSS软件进行统计分析，结果表明：（1）室内空气负离子浓度日变化与PM2.5浓度呈显著的负相关，与PM10浓度也呈显著的负相关；（2）自然条件下的室内空气负离子浓度日变化幅度规律为：PM10＞PM2.5＞空气负离子；燃烧香烟后的室内空气负离子浓度日变化幅度规律为：空气负离子＞PM2.5＞PM10。%With the measurement of the air positive and negative ion concentration, PM10 (Particulate matter) and PM2.5 (Fine particulate matter) indoor in November, 2013, Analyzing the statistics in SPSS. The results show that:(1)the daily variation of air anion concentration indoor shows significant negative correlation with PM2.5, and it sames to PM10.(2)the daily variation margin regular of air anion concentration indoor in natural conditions is that the air negative PM10>PM2.5>ions;the daily concentrations variation margin regular of air anion concentration indoor after burning cigarettes is that the air negative ions>PM2.5>PM10.
