简介：宝鸡市是我省重要的工业城市,经济发展迅速,市区工厂林立,人口密集,大气污染问题已引起各方面的关注。大气污染程度与气象条件之间的关系非常密切,同样的污染源在不同气象条件下所造成的地面污染程度千差万别。因此,研究分析大气污染物的扩散、稀释规律,寻找地面污染物浓度与气象条件的关系,对防止和控制污染都有重要的参考价值。

简介：对食用菌中SO2残留的快速测定方法及各种影响因素进行了研究。样品经酸化后，用预经痕量碘蒸气致蓝色的淀粉指示纸检测，样品产生的SO2使其褪色。淀粉指示纸的制备方法、观察时间和测定温度均对检测结果有影响。该测定法对SO2的最小检测限为5mg／L，可用于食用菌产品中SO2残留量的定性检测和半定量分析，具有快速和简便的特点。

简介：在密闭条件下,采用静态熏气法研究不同化学型（芳樟型、脑樟型）樟树1年生苗木、枝条在SO2伤害阈值时（0.5g/m3×4h）对SO2的吸收能力及熏气后的恢复能力,结果表明,芳樟型1年生苗木对SO2吸收量为450.6mg/m2,芳樟型枝条对SO2吸收量为451.8mg/m2;脑樟型1年生樟树苗对SO2吸收量为597.6mg/m2,脑樟型枝条对SO2吸收量为809.4mg/m2。芳樟型樟树1年生苗木、枝条与脑樟型樟树1年生苗木、枝条熏气后恢复能力无显著差异。

简介：摘要：我国当前现代化的社会建设中，对于能源物质的使用越来越高，因此不免对社会环境带来一定的污染问题。其中对生产中的硫磺回收氧气处理中，要加强对内部SO2的排放控制，在本文的分析中，主要阐述了硫磺回收烟气SO2达标排放的影响因素，并给出了处理对策，为相关工作人员提供参考。

简介：and the total capitalization of the US market increased almost nine-fold (from $ 1.9 trillion to $ 16.6 trillion) over the same period.c. The Dramatic Growth in Securities Issuance Volume Since 1990 Another way of measuring the rise of capital markets is to examine whether their share of annual corporate financing activity has grown relative to that of other sources of funding. Security offerings by US issuers accounted for two-thirds of the global total throughout 1990-1999,before more than doubling to $ 1.22 trillion in 1999--rivaling the US total. The global value of M&,this was a period of very rapid growth in the capitalization of markets in every country except Japan. Total world market capitalization increased over ten-fold (to $ 35.0 trillion) between 1983 and 1999

简介：and banks and is usually arranged by issuing houses and merchant banks. Stock exchanges are also part of the capital market in that they provide a market for the shares and loan stocks that represent the capital once it has been raised. It is the presence and sophistication of their capital markets that distinguishes the industrial countries from the developing countries,in both developed and developing countries over the past decade. And also capital markets are in fact winning the present and seem likely to dominate the future of corporate finance in developed and developing countries alike.a. The Stable Role of Commercial Banking in Modern Economies Ordinary "relationship banking" appears to be (at best) holding its own as a source of corporate financing around the world,Section 1 shows why has the global capital market grown so rapidly in recent decades. Section 2 talks about the continuance of the growth throughout the 2000s.Body1. Why has the global capital market grown so rapidly in recent decadesIn recent decades

简介：today's China takes a serious position in world's economy. Its innovation and opening policy make china keep achieving high GDP growth rate. This drives the global capital market keep growing. Summary and ConclusionsThis essay examines the impact of share issue privatizations (SIPs) on the growth of world capital markets (especially stock markets). I begin by documenting the increasing importance of capital markets,in corporate financial systems around the world. I then show that privatization programs-- particularly those involving public share offerings--have had a dramatic impact both on the development of non-US stock markets and on the participation of individual and institutional investors in those stock markets.This has told the reason of the fast growth of global capital market. And then I succinctly indicated the continuance of the rapid growth,a series of share issue privatizations can indeed promote the growth of global capital market

简介：早在60年代人们就把环境空气分析仪和工业过程监控仪直接用于污染源排放监测。由于当时研制的烟气稀释系统稳定性差，环境空气分析仪在污染源排放监测中的应用没有成功。60年代末期至70年代初期，德国和美国成功地研制、生产、发展了排放监测系统，重新设计了测量高浓度气体的环境分析仪和不用抽取样品而是将探头直接插入烟道测量烟气的现场分析仪，并不断对仪器进行改进。在美国，第一台连续排放监测系统出现于1971年，但由于某些技术原因，连续排放监测系统制造工业的发展停滞不前。

简介：摘要近年来，国家环保法规对SO2的排放要求越来越严格，自2017年起现有企业执行新的石油炼制工业污染物排放标准，硫磺回收装置SO2排放质量浓度小于400mg/m3。目前某石化有限公司50kt/a硫磺回收装置采用2级转化Claus制硫工艺，尾气处理采用SSＲ工艺，将处理后的净化尾气热焚烧，尾气焚烧炉出口设置蒸汽过热器，烟气取热后自高空排放。因此，研究降低硫磺回收装置烟气SO2排放浓度的技术路线，满足新的环保标准要求尤为迫切。
