Opportunities and Challenges in Chinese Housing Industry

This article studies the opportunities and challenges in housing industry in China and proposes its development tendency.     

Analysis of Heat Transfer and Optimal Parameters of Multi-louvered Fin Condenser

The authors conduct the experimental study and optimal computing for the condenser of automobile air conditioner. The especially the properties of heat transfer and flow at the side of air when using shutter fin. The authors the influence of several combinations of fin's geometry parameter to heat transfer and flow resistance. The maximal heat transfer is used as a criterion relation to select the fin's geometry parameters in the same facing air area of condenser. Furthermore, a program is designed to conduct optimal computing, and the computing results are basically consistent with experimental results. It shows that the optimal method is reasonable and the results can be applied to engineering practice.     

Design of Reef- blasting Project and Analysis of Regulation Effect for Fuling to Tongluo Canyon Reach in Three Gorges Reservoir Region

After the completion of the Three Gorges project,the navigation conditions of the reservoir region will be improved evidently,which has laid the foundation for straight run of the 10,000-ton-class fleet to Chongqing Port,and is the promotion of the development of shipping in Yangtze River.But according to the standard of the 10,000-ton-class fleet,there are still some reaches of the reservoir region can not meet the requirements of the waterway on smooth and safe navigation.Therefore,some regulation measures should be adopted to eliminate these obstructions.It is one of the important parts in the reservoir region waterway regulation work for the Fuling to Tongluo canyon reach blasting project.30 reef obstacle blocks of 14 reaches in this project were removed by blasting.Based on the analysis of obstruct features of various rocks,according to the standard of the 10,000-ton-class fleet,the design parameters and blasting regulation program were put forward,and the regulation effect is analyzed and forecasted.     

Study on Inheritance and Development of Traditional Street, Lane and Courtyard in City Growth

City is not a concretionary but a dynamic matter. It should keep close touch with the animated tradition, and we should look forward to its future too. Thus we will be facing with the problem of inheritance and development of the tradition. Because the tradition is a potential for good as wdll as for evil, it can promote the development of a thing, and also may hinder its progress, so there should be correct attitudes to the traditional inheritance. This paper studies the modem application of the traditional street, lane and courtyard, which brings new vitality to the tradition and imparts fresh life to the modem city.     

Prediction of the Economic Development for the Circumjacent Reservoir Region of the Longtan Hydropower Project Using Grey Quantitative Analog

In order to overcome some technical difficulties,we adopt ingenously the grey models combined with the quantitative analog method,and select the Dan Jiangkou Project which has accumulated practical operation data for a long time as the analog project to predict the economic influence for the circumjacent reservoir region of the Longtan hydropower project.On the basis of analog we have built various industrial economic grey models,and compare them with the corresponding predictions for the unconstructed reservoir case.The predictions of the former are greatly larger than the later ones.and hence provides a certain scientific basis for the central leaders to make a decision for constructing the huge hydropower project ultimateiy.     

Analysis of Project Audit''s Function and Civil Action

Audit takes a unique status and has obvious function in financial surveillance system.The Audit is used to superintend the factuality,validity and virtue of fiscal and financial income and expenses.In the renewed China Audit law the functions and status of official audit have been intensified,and the qualification and status of Audit department as executing office is confirmed.This paper analyzed the official construction project audit's function and legal status.     

Discussion about the Agent- Construction System of Governmental Project in China

The agent - construction system, as a new public project management mode, has been practiced in some cities and attracted attention from the society. This paper firstly studies the features and operation modes of agent - construction system, and discusses the agent - construction system from the viewpoints of promoting competition, nourishing agent -construction enterprises, setting up a supervisory and encouraging mechanism, and its connection with the governmental project procurement system etc.
