Research on the System and Models of Society-Economy-Environment Appraisal for Construction Project

The society-economy-environment appraisal for construction project can help our government to control macro-economy, make correlation policy and formulate laws and draw up city plan.It has great influence on the sustainable development of our society and it is the demand of the law for the environment evaluation in China.This paper introduced the basic structure of society-economy-environment appraisal system for construction project and the thought of elements transaction.Using the method of AHP, the model of project analyzing and optimizing selection is designed.For the more, the methods of the optimizing models on the selected schemes are put forward.Finally, the integrative analysis has been made on the system design and appliance of this appraisal system.     

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.     

An Estimate on the Casual Relation between Financial Development and Economic Growth

This paper firstly discusses the relationship among money,real interest rate and economic growth of China. Then estimates the causality between financial development and economic growth by Bivariate Granger Casual Relation Test. The conclusion suggests that economic growth stimulate financial development more in China.     

Sampling Investigation on Inhatitant Domestic Tap Water Consumption Situation and It’s Characteristics Analysis

Economics.Through sampling investigation and analysis on inhabitant domestic tap water consumption situation,it is given that economic factors are the main factors influence inhatitant's water consumption.The functional relations among inhabitant's income and water consumption,water price and consumption are given. The tap water's income elasticity of demand and price elasticity of demand is analyzed, along with the fluctuating range month by month of inhabitant's water consumption.Finally ,this paper offers the reference data for planning the ability of water supply and making policies of ladder water prices.     

Robust Adaptive Control Based on On-line Identification to Multi-parameters

In system controlled,Sampling these parameters and with parameters for controller in time, it is an object to adaptive control. The article presents a scheme that the structure parameters on it's model and model parameters is robust identified by on line, while to optimal of algorithm on adaptive control is fulfilled. In control scheme, method of intelligent identifying to the structure parameters(levels of model) and algorithm of robust pole placement are introduced also It is advancer for already mentioned scheme. Whole scheme presents new model on adaptive control.     

Microstructures, Reaction Kinetics and Properties of Reaction Between Magnesium and Silica Glass

In earlier calculation models,the stiffness centers in frame-shear wall structures have been located by the structural torsion stiffness.However,the results are illogical owing to the difference between the distortion character and the shears distribute mechanism of the frames and shear walls.In this paper,a new formula for calculating story stiffness is introduced,which can consider the stiffness of the frames and shear walls at the same time.The structural stiffness centers,the torsion eccentric distances and torsion effect are calculated,and the stiffness of elements is considered also.It is shown that the concept of the presented stiffness model is clear and the results are reasonable,which can be used to calculate the appreciative torsion effect.

小型农村水利改革思路

在分析小型农村水利的特点和性质的基础上,理清了小型农村水利改革的思路。认为：小型农村水利具有工程小、数量多、分布面广,地位重要但易受忽视,涉及范围广、服务功能多、公用性、垄断性、群众性、政策性、公益性、系统性和整体性强,季节使用、经营管理难等特点。改革的核心要按照“谁受益,谁负担,谁投资,谁所有”的原则,组建用水合作组织,明晰所有权。改革的关键是把所有权与经营管理权分开,采用灵活多样的形式加强经营管理。改革的实质是建设与管理制度改革,不能简单理解为“产权制度改革”。
