The Study and Development of Environment-Monitoring Biosensors

A review on environment-monitoring biosensors is presented.During recent years,various environment-monitoring biosensors are fast developed.They are applied to various areas,such as aquatic environment,atmosphere environment et al.The developing trend of environment_monitoring biosensors is also discussed.     

Nash Equilibrium Mechanic of Environmental and Human Capital

The externality of surrounding is introduced into the 2-capital of economical increasing models, which includes human factors, to explore the influences of circumstances contradiction on the human capital formation. The normal and special nash equilibrium of environmental and human capital is presented through a limited boundary model of overlapping generations. The character of equilibrium trail and its economical meaning are examined. The study on the model shows that laissez faire economy will be either stagnant,growing,or collapsing in the long-run,depending on the returns of the learning technology with respect to the two kinds of capital,the initial state of economy,and the relative price of the environmental and consumption goods.     

Power Frequency Electric Field Caused by EHV Lines and Its Effect

Mathematical model of power frequency electric field is established based on Charge Simulation Method(CSM) to analyze power frequency electric field caused by EHV lines with overhead ground wires and its effect, which are entering the megalopolis. Calculative method on the electric field under the transmission lines is analyzed and validated. According to the criterion of environmental evaluation, the distributing characteristic of electric field is summarized, in case of various arrangement manners of lines. At last, some advice and methods of eliminating electric field under the transmission lines entering the megalopolis is proposed with regard to protecting environment.     

Research on Measurement and Report of Environmental Accounting

In this paper, the problems of bringing natural resources and environmental condition into accounting are discussed and lay emphasis on object measurement, imaging and disclosure in accounting report of environmental accounting. The author suggests that the environmental accounting is the necessary production of global economy for sustainable development in modern society; it is also a new ecological accounting subject formed by the result of environmental economies and accounting penetrating into each other. As a contribution of accounting circles to sustainable development, environmental accounting has become a hot topic in recent years.     

A MATHEMATICAL MODEL OF FUZZY EVALUATION METHOD FOR ENVIRONMENTAL POLLUTION

The problem of fuzzy evaluation of environmental pollution is importantboth in environment science and in environmental protection.Usual evaluationmethods have their own characteristics.This paper puts forward a mathematicalmodel of fuzzy evaluation method in grades by means of systematic analysisfor environmental pollution.At the same time,it assigns weighted values byordering based on paired comparison.

曹娥江上游支流水环境容量的研究

本文针对我国东部地区典型河流-曹娥江的污染现状，选其上游支流长昭水库至南津桥河段进行了水环境容量研究，根据该河段的水流特性和水文、污染源的调查资料及水质实测资料，应用数学模型，分段研究了该河段各月的水环境容量。结果表明：该河段局部水质污染严重，水环境容量所剩无几。本项目的研究为实施污染物总量控制提供基础资料，为曹娥江流域水污染控制的管理和决策提供了科学依据。
