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.
根據(jù)分子拓撲理論 ,提出二類化合物分子中頂點原子價點價值δi H的計算方法 ,并由δi H構(gòu)建分子結(jié)構(gòu)信息價連接性拓撲指數(shù) 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.
在垃圾焚燒過程中,PVC含量的增加可導(dǎo)致HCl產(chǎn)生量的增加,并有可能成為二生成的氯源。
In this paper, a way to control dioxins in a system of MSW incineration is proposed.
控制垃圾焚燒二產(chǎn)生與擴散分三部分 :首先 ,通過預(yù)處理除去原生垃圾中的聚氯乙烯塑料 ,從源頭上控制垃圾焚燒二產(chǎn)生的物質(zhì)基礎(chǔ) ;其次 ,垃圾焚燒爐采用組合式循環(huán)流化床鍋爐 ,實行垃圾先低溫熱解氣化 ,然后高溫燃燒垃圾熱解氣體的方式 ,同時在爐內(nèi)加入添加劑實現(xiàn)穩(wěn)定燃燒和部分脫氯 ,以減少二在爐內(nèi)生成和爐后形成量 ;最后 ,在煙氣尾部采用吸附劑吸附二 ,并與布袋除塵器配套使用 ,控制二的尾部擴散。
An Review of the Methods in Common Use for Dioxins Analysis;
介紹了目前二類物質(zhì)常用的前處理與分析測定方法,包括提取方法、凈化方法和定性與定量方法。
The chemical composition,main pollution sources and toxicity of dioxin, its pollution situation aboard and relative standards in Japan, USA, Germany etc are described.
文章論述了二的化學(xué)成分及主要來源 ;二的毒性 ;日本、美國、德國等國二惡英污染狀況及各國制定的標
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.
從中、西方思想發(fā)展的動態(tài)過程考察老子思想的方法論意義,認為:道與一、二、三的關(guān)系是一種循環(huán)遞進的關(guān)系,對這種循環(huán)遞進的區(qū)分分為三個層次:初級的區(qū)分是本源的區(qū)分,次級的區(qū)分是哲學(xué)的區(qū)分,深層次的區(qū)分是美學(xué)的區(qū)分。
