应用fx—180计算器编制一般计算程序,对单个计算式而言已比较容易实现。能不能对多个计算式采用通用程序,不重编程序,减少每次输入程序的麻烦,这正是分析人员所期望的。笔者将所编通用程序在环境分析计算中对20多个算式归纳的应用,选择代表例实际运行分述如下:对监测分析项目可分类为:1、比色分析法项目如Cr、Hg、 相似文献

本文介绍了一个用BASIC语言编写的微机程序,即CDI程序。该程序是根据最小二乘修正加上外推的原理编制的,用于粉末衍射数据的晶胞参数计算和粉末图指标化。CDI程序可以处理所有晶系的衍射数据并得出令人满意的计算结果。程序已在IBMPC/XT,长城0520CH及C.S.重型微机上运行了好几年并解决了一系列实际问题。 相似文献

对固定污染源烟气连续监测系统检测时,其中气态污染物相对准确度的计算涉及到大量数据。通常的计算过程比较繁琐、费时。针对这种情况,本文作者设计了一个相应的MATLAB程序,该程序充分利用MATLAB语言强大的矩阵计算能力,分别将连续监测系统中SO2、NO和O2的浓度以矩阵输入,调用该程序即可快速得出所求结果,解决了常规计算方法繁琐、所耗时间长、容易出错等缺点。 相似文献

This paper describes the first four years' experiences with Erasmus University's “International Off-Campus PhD Programme on Cleaner Production, Cleaner Products, Industrial Ecology and Sustainability.” The proposal for this innovative, off-campus programme was made in 1992, in response to expanding needs for providing environmental professionals the opportunity to continue their employment and to simultaneously work toward fulfilling the requirements of a PhD.After receiving approval and initial financial support from the Board of Deans of Erasmus University, the first INTENSIVE (INTENSIVE is the term used to describe the annual, two-week long training programme within which the new PhD candidates, as well as those who have been in the programme for a year or more, meet to learn more about the rapidly evolving areas addressed by the programme and to report on progress made in each candidate's PhD thesis research. The Erasmus faculty and invited supportive co-advisors and other visiting scholars contribute to the scholarly input and candidate guidance.) of the new International PhD Programme was held in October 1995. Since then the programme has expanded and progressed. As of the academic year 1998/1999, twenty-one PhD candidates from eleven countries in five continents were actively pursuing their PhD research and thesis development within the Programme. Six new candidates were admitted during the November 1999 INTENSIVE. 相似文献

Rethinking the role consumption plays in individual well-being and societal development is key for addressing pressing environmental problems. We perceive the need to envision consumption as a social activity, which requires the active engagement of consumers in order to better enhance their quality of life. The paper focuses on the framework of Product Service Systems, one particular programme for more sustainable consumption. After reviewing the potential benefits and limitations of this programme, we explore the opportunities to learn from participatory and community-based strategies like LETS. 相似文献

Population screening for neural tube defects is possible by measuring maternal serum alpha-fetoprotein levels with appropriate follow-up as required. British Columbia has approximately 39 000 births annually and the incidence of neural tube defects is 1–55 per 1000 births (0–94 per 1000 livebirths). Results from a cost-benefit analysis suggest that the outlined screening programme would be cost-beneficial for British Columbia. Other important factors essential to consider before instituting a population screening programme are discussed. 相似文献

西南涌属于北江下游大堤左岸的分洪河道。西南水闸重建后,通过调节西南水闸闸孔的开度,引入北江水进行河涌整治,将导致西南涌上游污染物向下游迁移,但涨潮时须关闸门,不让污染较严重的西南涌水进入北江。由于下游珠江口河水的上溯,上下游河水交汇处河水流速最小,污染物的交换能力最弱,导致污染物的最大浓度沉积。本研究将应用珠江口一维感潮河网模型,从水环境效果的角度出发,模拟分析在水环境容量较小的平、枯水期,不同的引水方案对水质的影响程度,提出最佳引水方案和河涌整治措施建议。 相似文献
