新疆主要自然灾害及其减灾策略

新疆是一个自然灾害较多的地区,地震灾害、地质灾害、气象灾害、洪水灾害都比较频繁。本文在概述、分析上述灾害的基础上,提出了减轻自然灾害的策略。     

减灾平衡点

文章依据经济学的原理提出了减灾平衡点的概念,并初步分析了它的特征及其实际意义。所谓减灾平衡点是指社会总体投资利益最大时减灾投资在社会总投资中所占的位置;此时,减灾投资利润率与社会正常生产投资利润率相当。     

MANGANESE CYCLE IN IMPOUNDMENT WATER

Manganese entering impounded water will undergo a cyclic transformation. Oxidation precipitates manganese from top waters. At the bottom of the lake, biological activity will render manganese soluble by both intracellular as well as extracellular activity. The study was made to demonstrate that biological reduction and transformation, organometallic complexation, together with the presence of carbon dioxide and the lowering of pH all have some effect on the solubility of manganese. Dissolved manganese may be brought back to top waters during the lake overturn and therefore deteriorates the water quality.     

中原输气信息系统的建立与应用

在Ｗｉｎｄｏｗｓ环境下,以Ｍａｐｌｎｆｏ（ＧＩＳ）软件为主要支持工具,结合ＶｉｓｕａｌＢａｓｉｃ为中原输气公司开发的信息管理系统既可用于平时企业管理,也可用于抗震救灾,是企业管理极为有效的工具。     

对中国防灾减灾立法体系的探讨

中国是自然灾害和经济、社会发展中人为突发事件灾害普遍、灾情严重的国家。灾害已直接影响和制约着国家的经济建设、社会发展和公众的安全。要把防灾减灾作为中国的基本国策。为此,必须长远规划和全面制定中国的防灾减灾立法体系,以适应２１世纪中国减灾安全与可持续发展的战略任务。本文就编制中国防灾减灾立法体系应遵循的指导方针、基本原则及方案的框架设想全面提出研讨建议。     

Natural gas engine driven heat pump system – a case study of an office building

ABSTRACT

An eQUEST model was developed to conduct a simulation study of a natural gas engine-driven heat pump (GEHP) for an office building in Woodstock, Ontario, Canada. Prior to the installation of the GEHP, the heating and cooling demands of the office building were provided by rooftop units (RTUs), comprising of natural gas heater and electric air conditioner. Energy consumption for both GEHP and RTUs were monitored for operation in alternating months. These recorded energy consumptions along with weather data were used in the regression analysis. The developed eQUEST models were validated and calibrated with the regression analysis results with respect to the ASHRAE Guideline 14–2014. The eventual models were then applied to investigate the potential annual energy consumption, greenhouse gas (GHG) emission and energy cost savings achieved by using the GEHP in Woodstock, and other cities in Canada, particularly in Ontario.
