天然放射性物质及环境问题

天然放射性物质（ｎａｔｕｒａｌｌｙｏｃｃｕｒｒｉｎｇｒａｄｉｏａｃｔｉｖｅｍａｔｅｒｉａｌｓ，简称ＮＯＲＭ）广泛存在于地层中，当石油或天然气从地下开采出来时，痕量的天然放射性核素如镭、氧等也随之采出，并分别集中于管道及设备的垢层或天然气加工装置的内壁薄膜上。文章在对外文资料调研的基础上，将ＮＯＲＭ的有关知识、存在场所、对人体潜在的危害途径及有关辐射防护方法进行了介绍。     

多孔零件水射流清洗机研制

根据生产需要，我们研制了“水射流自动清洗机”，采用水射流技术与清洗剂相结合，完成工序间、装配前的机械零件（尤其带有小孔、盲孔等多孔零件）的清洗，取得了普通清洗方法难以达到的清洗效果。该机在国内同类型清洗机中，首先采用水射流技术，全部流程，由ＰＣ机控制，加上水循环处理系统，其清洗自动化程度高，清洗速度快，清洗液消耗少，在实际生产中取得了良好效果。     

Use of a generalized linear model to evaluate range forage production estimates

Interdisciplinary teams have been used in federal land planning and in the private sector to reach consensus on the environmental impact of management. When a large data base is constructed, verifiability of the accuracy of the coded estimates and the underlying assumptions becomes a problem. A mechanism is provided by the use of a linear statistical model to evaluate production coefficients in terms of errors in coding and underlying assumptions. The technique can be used to evaluate other intuitive models depicting natural resource production in relation to prescribed variables, such as site factors or secondary succession.     

Community Exchange and Training in the Suid Bokkeveld: A UNCCD Pilot Project to Enhance Livelihoods and Natural Resource Management

Community knowledge exchanges have played a key role in developmental processes in the Suid Bokkeveld community of South Africa. Two exchange visits were undertaken with the support of the Department of Agriculture and an NGO, the Environmental Monitoring Group, which have led to local economic development and enhanced capacity to manage natural resources in a sustainable manner. These pilot projects were undertaken within the framework of the Community Exchange and Training Programme of the Global Mechanism of the United Nations Convention to Combat Desertification (UNCCD). The methodology applied included facilitation to develop a community-based vision for development, in terms of which the community exchange process was designed. A Facilitation Team of service providers conducted preparatory workshops, and identified potential partner communities. Two exchange visits were carried out, one focused on Rooibos production and marketing, and the other on community-based eco-tourism. Following report-back and planning workshops, emerging community-driven initiatives were supported through their formative stages. The initiatives have not only resulted in enhanced livelihoods, but the methodology has also been applied widely in a number of different contexts.     

城市生态环境质量评价初探

以新疆乌鲁木齐市、石河子市、克拉玛依市为例,依据城市生态学理论,对城市的生产位、生态位、环境位进行评估,并对评价结果进行综合分析,以确定城市生态环境质量的优劣,以此反映城市经济发展、人类各种活动和环境保护之间的适应程度.
