2013年1月宁波市ＰＭ2.5污染的形成过程与传输规律
宁波 模式 过程分析
2015/8/10
为了深入认识宁波市冬季细颗粒物（ＰＭ２．５）的污染特征和主要影响因素的作用规律，利用 Ｍｏｄｅｌｓ－３／ＣＭＡＱ 模式系统对 ２０１３ 年 １ 月宁波
市的 ＰＭ２．５污染形成过程进行了模拟分析．结果表明，宁波市 ＰＭ２．５的重点污染区主要分布在市区、北部地区及东部沿海，除了受到局地污染源
排放的影响外，对比非污染的情况，大气输入和气溶胶生成作用的增强是引起 ＰＭ２．５污染的主导因素，其中水平...
在一台整车排放达到国Ⅲ标准的YC4D140电控单体泵增压中冷柴油机上加装甲醇喷射系统，改成柴油甲醇组合燃烧（DMCC）发动机。使用AVL 415S烟度计和DMS 500快速颗粒物光谱仪研究不同后处理器对DMCC发动机颗粒物（PM）排放的影响。试验结果表明，各工况下单独CDPF、DOC+CDPF基本可以消除发动机产生的干炭烟。DOC+CDPF后处理方式与单独CDPF相比，颗粒物捕集效率明显提高，且前...
目的：探讨北京市大气颗粒物（PM10及PM 2.5）污染对居民循环系统疾病死亡的影响。方法：连续监测2007年至2008年北京市大气中PM 2.5日均浓度，并收集同时期海淀区居民循环系统疾病死亡数据、北京市大气污染物和气象条件资料，应用双向对称性病例交叉研究和条件Logistic回归对数据进行分析，同时调整了性别、年龄及季节等潜在混杂因素的影响。
