The structural efficiency relationship of the log K ow of n-octanol /water partition coefficients(K ow ) of the polychlorinated dibenzo-p-dioxins PCDDs compounds is studied by usi.
根据分子拓扑理论 ,提出二类化合物分子中顶点原子价点价值δi H的计算方法 ,并由δi H构建分子结构信息价连接性拓扑指数 mχH(m =1,2 ,3,。
In the incineration process of MSW, the generation of HCl is positively correlative to the amount of PVC in the MSW, which possibly become the chlorine source of dioxin generation.
在垃圾焚烧过程中,PVC含量的增加可导致HCl产生量的增加,并有可能成为二生成的氯源。
In this paper, a way to control dioxins in a system of MSW incineration is proposed.
控制垃圾焚烧二产生与扩散分三部分 :首先 ,通过预处理除去原生垃圾中的聚氯乙烯塑料 ,从源头上控制垃圾焚烧二产生的物质基础 ;其次 ,垃圾焚烧炉采用组合式循环流化床锅炉 ,实行垃圾先低温热解气化 ,然后高温燃烧垃圾热解气体的方式 ,同时在炉内加入添加剂实现稳定燃烧和部分脱氯 ,以减少二在炉内生成和炉后形成量 ;最后 ,在烟气尾部采用吸附剂吸附二 ,并与布袋除尘器配套使用 ,控制二的尾部扩散。
An Review of the Methods in Common Use for Dioxins Analysis;
介绍了目前二类物质常用的前处理与分析测定方法,包括提取方法、净化方法和定性与定量方法。
The chemical composition,main pollution sources and toxicity of dioxin, its pollution situation aboard and relative standards in Japan, USA, Germany etc are described.
文章论述了二的化学成分及主要来源 ;二的毒性 ;日本、美国、德国等国二恶英污染状况及各国制定的标
This paper has observed the significance of Laozi s methodology through the dynamic process of east and west thinking development,and proposed that the relationship between Tao,one,two and three is circularly progressive,which can be divided into three levels, the separation of the origin,the separation of philosophy and the separation of aesthetics.
从中、西方思想发展的动态过程考察老子思想的方法论意义,认为:道与一、二、三的关系是一种循环递进的关系,对这种循环递进的区分分为三个层次:初级的区分是本源的区分,次级的区分是哲学的区分,深层次的区分是美学的区分。
