团结协作开创未来--卢鉴章主任委员在中国煤炭学会环境保护专业委员会1999年年会暨学术研讨会上的讲话(摘要)

中国煤炭学会环境保护专业委员会1999年年会暨“煤矿矿区水资源保护与水资源化”学术研讨会今天在宜昌召开,这是我们专业委员会成立后的第四次年会,也是第四次学术研讨会。在此,谨向参加这次会议的同志们表示热烈的欢迎和感谢！     

WebGIS在水资源环境监测中的应用

采取面向对象软件设计思想．利用网络数据库技术，WebGIS技术等，设计水资源环境监测系统。分析了系统结构与功能模块以及数据库构成及系统安全性保障。     

Prevalence and clinical significance of anticardiolipin antibodies in pregnancies complicated by parvovirus B19 infection

Anticardiolipin antibodies were measured in 60 pregnant women with acute parvovirus B19 infection. Test results for eight (13.3 per cent) women were positive for anticardiolipin antibody. Six of these eight women became negative later, yielding a prevalence of anticardiolipin antibodies of 3.3 per cent (2/60) 6 months after acute parvovirus B19 infection. Anticardiolipin antibody positivity was not associated with an increased risk of abortion, fetal death, or maternal complications. This study suggests that there is an elevated frequency of anticardiolipin antibodies in pregnant women with acute parvovirus B19, probably representing an epiphenomenon. However, this is not associated with an adverse maternal or perinatal outcome.     

潜艇舱室气态污染与环控生保技术发展趋势

首先介绍了潜艇舱室主要气态污染物,分析了其主要来源及其对人体的危害.然后基于潜艇大气控制系统、供氧系统、二氧化碳清除装置、空气净化装置、通风系统、应急供氧、潜艇大气环境监测系统等方面简述了潜艇舱室环境空气监测与控制技术的现状和发展趋势.关注了低温冷冻技术、光催化净化技术、等离子体催化净化技术、活性炭纤维吸附技术等一些具有开发应用潜力的监测和净化新技术.最后指出我国在潜艇大气环境领域的研究发展与国外先进水平还存在较大差距,在及时跟踪引进国外先进技术的同时,应注重该领域的基础性研究.     

Carbon Dioxide Emission Reduction Scenarios in Mexico for Year 2005: Industrial Cogeneration and Efficient Lighting

An analysis of the impacts on Mexican energy demand and associated carbon dioxide (CO₂) emissions in the year 2005 due to efficient lighting in the commercial and residential sectors and cogeneration in the industrial sector is presented. Estimation of CO₂ abatement costs and an incremental cost curve for CO₂ mitigation options are considered. These technologies are cost effective opportunities, and together are projected to reduce CO₂ emissions in 2005 by nearly 13 percent. Implementation of efficient lighting is already part of the demand side management (DSM) programs of the Mexican state-owned utility. However, there are important barriers that may hinder the implementation of large scale cogeneration plants.     

大气中挥发性苯系物的Carbotrap吸附气相色谱法

本文研究以Ｃａｒｂｏｔｒａｐ作吸附剂，在常温采集大气中挥发性苯系物，直接采用热脱附气相色谱分析。对新型吸附剂Ｃａｒｂｏｔｒａｐ的采样－脱附－分析精度，回收率，突破体积等作了试验。本法具有灵敏度高，操作简单，不需复杂的样品预处理，色谱峰好，吸附剂可反复使用等优点。可对大气中１０－９级苯系物进行测定，ＲＳＤ≤３．５％。     

膜分离技术用于非电解质除杂

介绍电渗析装置工艺及基本原理，提出使用离子选择性透过膜的依据及极限电流的确定方法．论述了不同方法对冷冻液与ＮａＳＣＮ分离效果影响，指出采用电渗析法分离冷冻液中的ＮａＳＣＮ，使除杂率可达９５％以上。本工艺为腈纶冷冻液除杂及防治污染提供了新途径。     

合肥台地电阻率干扰综述

本文首先叙述了合肥台地电阻率值ρS的观测环境,并根据合肥台近年几次ρS的异常变化,通过初步理论分析,找出了DD-1接地体、电缆沟开挖、大气降水、太阳黑子引起的自然电场对ρS的干扰,为以后排除和识别地电干扰起参考作用.
