新疆环境保护网站建设的现状与发展探讨

1997年建成的＂新疆环境保护＂网站是全国第一家环保门户网站,也是新疆第一家政府类网站,新疆环保网站建设与发展已经历风雨兼程的10a,现在正进入一个崭新的发展阶段.回顾、总结和展望新疆各级环保网站的发展,吸取发展中的经验与教训,探索新疆各级环保网站建设中的规律,对新疆环保电子政务的＂理性建设、快速推进＂大有裨益.     

硫氮沉降下西北荒漠煤矿区周边土壤性质的变化特点

近年来中国大部分区域大气硫、氮沉降速率趋于平稳甚至下降,但西北地区煤炭行业的快速发展使得硫、氮沉降速率加快.燃煤电厂作为酸前体物的主要排放源之一,在其周围开展硫、氮沉降效应研究,可为合理评价煤矿区大气污染物控制措施的实施效果提供数据支撑.该文以宁东能源化工基地3个燃煤电厂为采样点,研究了电厂周围土壤化学和生物学性质的变...     

Biological Air Quality Monitoring: a Review

Air quality monitoring is currently ensured by captors measuring few physicochemical parameters, then they cannot evaluate unforeseen compounds and the interaction effects of pollutants. On the contrary, the use of bioindicators can answer these problems. Among them, plants are used in two ways:1) Passive bioindicators: trees, lichens and mosses are used to determine the distribution and even the contaminants long-term effects on vast zones and, possibly, the concentrations of pollutants to which they were exposed.2) Active bioindicators: tobacco and mosses make available the defective zones in plants and enable determination of deposition fluxes.Moreover, techniques based on biomarkers identification should increase the answer's sensitivity. However, the plants present the disadvantage of being unable to provide a response in a time lapse comparable with that of the on-line analysers. Lastly, the development of tools using animal cells should allow, in the near future, to measure the total polluting load under conditions close to those of the routine techniques. Then, the real impact of the contaminant on public health could be approached.     

合肥台CTS-1分析系统网络组建

本文阐述了利用UNIX和WIN98／2000互联的局域网技术，对CTS-1系统进行优化配置，组建CTS-1网络分析系统，实现CTS-1系统数据共享，提高地震分析的效率，确保数据备份。利用代理软件用一个MODEM让各个子机同时上网，同时充分利用台站现有的计算机设备，最大限度的实现地震监控、速报、分析以及地震研究的同时开展。     

Reinforcing the rules or integrating behavioural responses into road planning

Road planning is based on technical rules, know-how acquired from experience and professional expertise. A more ergonomics approach to road planning and safety analyses the psychological procedures used by the drivers. Every intervention on road network has an influence on safety. Increasing the coherency of all the interventions in the same area is the only possible way of producing areas with a better level of security. This paper deals with safety procedures, diagnostics and tools which can be used at different levels of intervention.     

成都冬季典型辐射逆温过程分析

本文利用测温声雷达的探测结果，借助同期探空和地面观测资料，分析了成都平原典型辐射逆温的生消演变规律，指出了其主要特征。这些结果对气候资源利用、污染气象条件的研究等具有重要意义。     

腐蚀性空气环境的分级及检测方法

介绍了国外有关腐蚀性空气环境的分级标准及其检测方法。环境中的腐蚀性气体可对电子元器件及自动控制设备产生腐蚀，影响其性能。根据腐蚀性的严重程度，美国仪器学会标准中将腐蚀性空气环境分为四级。环境腐蚀性置于腐蚀性环境中的铜试条进行检测。     

化工厂排放SO2对周围植物的影响

对某厂区及常年盛行风下风向地区植物受ＳＯ２危害情况进行了调查，并测定了部分植物叶片中的硫含量。从植物叶片中的硫含量可间接地判断大气被ＳＯ２污染的程度及植物对ＳＯ２吸收与抵抗能力的强弱。     

烟气镁法脱硫技术研究

氧化镁法脱硫，具有工艺流程短、脱硫效率高等优点，对控制烟气ＳＯ２造成的大气污染是一种行之有效的办法，具有推广应用的广阔前景。
