天然气压缩机站的安全生产管理

天然气压缩机组目前在油田的注气采油，增压外输等方面发挥着越来越重要的作用。在压缩机站的生产管理中，安全管理非常重要，建立健全安全规范将对压缩机站的安全运行提供保证。本文主要从油水管理，操作规程，容器管网，安全教育等方面进行阐述。     

新型循环冷凝固相微萃取方法的研究

首次提出一种新型循环冷凝萃取(CC-SPME)方法,并以乙硫醚为研究对象进行了分析检测。实验优选条件得出CC-SPME法的萃取时间,溶液加热温度和解吸时间分别为25min,75℃,4min。该方法的重现性,检测限以及回收率分别为7.54%,0.010mg/L,97%。实验表明,此方法的线性很好,而且与传统的浸入萃取法和顶空萃取法相比,具有更高的灵敏度。故而CC-SPME法是一种简单且灵敏的分析检测方法,值得做进一步探讨。     

生活污水回用作循环冷却水补充水处理方案的研究

分析了自来水及经膜生物反应器处理后的生活污水的水质指标，计算了水质判断指数，结果表明两者均为腐蚀性水质。通过静态缓蚀实验筛选合理的药剂，结果表明HEDP，ATMP，PBTCA的最高缓蚀率均高达90％以匕，HEDP，PBTCA与Zn^2＋复配的协同效果较好，复配后最高缓蚀率提高到98％以上。研究了考虑阻垢问题时的水处理药剂配方，通过正交试验筛选出最佳药剂浓度配方为：T-325：PBTCA：Zn^2＋=8：4：3。     

CLIMATE CHANGE AND NATURAL HAZARDS IN NORTHERN CANADA: INTEGRATING INDIGENOUS PERSPECTIVES WITH GOVERNMENT POLICY

A study of the relationship between natural hazards and climate change in the international context provides the background for a discussion of the expected changes. In the context of this global discussion, this paper reviews the current perspectives of those natural hazards that are likely to be influenced by climate change, using northern Canada as a regional case study. The northern implications of the United Nations Framework Convention on Climate Change are examined, including the status of climate change action by the northern territorial governments, the evolving role of indigenous people, and the responsibility for climate change impacts. The difficulties surrounding natural hazards research in remote locations, and the approaches of indigenous people to natural hazards are then presented. The paper concludes with a suggested policy approach for climate change and natural hazards in northern Canada, underscoring the need for more comprehensive adaptive strategies to complement the current tendency to focus on the mitigation of greenhouse gases produced in this region.     

自然降尘与常规气象因子的相关分析

笔者整理统计了１９９２年至１９９４年逐月自然降水和与之相应的常规气象因子监测数据，找到了自然降尘的季节性分布规律。在此基础上，求得了自然降尘分别与月平均气温、月平均气压、月平均风速、月平均温度、月降水量、月蒸发量的相关系数，并进行了检验，为污染预报工作提供了科学依据。     

基于多媒体技术的<中国自然灾害>教育软件开发

根据社会公众对中国自然灾害信息的需求，开发了《中国自然灾害》多媒体教育软件。软件以区域灾害系统理论为指导，设计了内容框架、基本体系。通过声音、影像、动画和文本等媒体形式可向社会深层次、多角度地介绍中国自然灾害信息，普及减灾知识，增强社会防灾减灾意识。

SOUND POLICY OR SMOKE AND MIRRORS: DOES ECOSYSTEM MANAGEMENT MAKE SENSE?1

ABSTRACT: Protection of ecosystems as entities on the landscape has attracted a wide range of support. Ecosystem-based public policies are claimed to be more effective, efficient, and scientifically sound than other approaches to environmental and natural resource policy. The ecosystem concept was never intended to serve as a public policy guide or to determine landscape units for land management purposes. This paper critically examines the use of the ecosystem concept in public policy and land use management and analyzes the proposed rule to manage the National Forest System according to ecosystem management principles. The concept is found to be unsuitable as a basis for guiding environmental and natural resource public policies in general while the proposed rule to manage the national forests according to ecosystem management principles is shown to be incoherent.     

河南省综合自然景观旅游资源的区际比较研究

针对目前河南省综合自然景观旅游资源区域整体优劣定量评价不足的情况，选取了国家重点风景名胜区、国家水利风景区、国家自然保护区、国家森林公园和国家地质公园5类综合自然景观类旅游资源，采用绝对数量、地均数量、人均数量3种评价指标和定量分析方法，对河南省18个省辖市的综合自然景观旅游资源进行了比较，阐述了河南省综合自然景观旅游资源空间分布的基本状况和旅游资源的区域发展重点。
