Research on Financing Plan for International Cooperative Project in Housing Industrialization

Housing industry is a prop industry with great potential, but it is restricted by shortage of funds. So it is necessary to probe the financing system of housing industrialization in China. This paper puts forward a financing plan for the international cooperative project in industrialized housing in Chongqing. Furthermore, it investigates the concrete financing system of the whole housing industry.     

Revelation Game of the Private Information Under Asymmetric Information

Because of the existence of the private information, the informed trader can make excess payoffs by using the information advantages. And also the informed trader can choose the trade strategies to attain the up most excess payoffs. However, he may lose his information advantages. This paper analyzes the conditions when the informed trader can make use of the private information and its optimal times underlying the framework of the strategic market game.     

Review on the measurement theories of enterprise knowledge management during the past three years in China

The implement of enterprise knowledge management gives rise to extensive research on its measurement. Based on the existing measurement theories and evaluation index systems of enterprise knowledge management during the past three years in China, this paper analyzes the problems in measuring target and designing the evaluation index system in the existing research findings, and explains detailedly why measurement target of enterprise knowledge management should be "level evaluation" instead of "performance evaluation", and definitely points out the meanings of enterprise knowledge management level and significance of its evaluation. This paper also indicates that the design of the evaluation index system should be complete, reasonable, proper and operable.     

Approach to Effective Control on the Project Investment

In this paper, in allusion to the three kinds of serious overvaluation (the budgetary estimate of project construction exceeds the rough estimate, the budget exceeds the budgetary estimate and the final accounts exceed the budget) causing uncontrollable project investment often appeared in domestic project construction,the main causes for that are analyzed. That is, the frequent project change and the malpractice of the cost managing system. In this paper, according to some real projects,the kinds and causes of project change are clarified and the malpractice of the cost managing system is analyzed. The effective approaches of reducing the project change, especially the united surveying and improving the cost managing system in order to make the effective control of the project investment are realized.     

Computer Simulation for Analysing the Melting Action of Mould Powders During Continuous Casting

When analysing the performance of casting powders in a specific casting machine, the thickness of liquid slag is a very important parameter. If the liquid slag thickness is not kept above a certain minimum value during the continuous casting operation,the surface and internal quality of the cast products will be jeopardised because lubrication between the strand and the mould is impaired . It is necessary, therefore , to choose the appropriate type of mould powder .In the industrial experiments, it is very difficult and expensive to study this sensitivity by introducing controlled variation in one parameter while keeping all the other constant. Numerical and computer simulation methods are used in the study .They can predict the liquid slag thickness developed above the liquid steel and distribution of the temperature. The sensitivity of the liquid slag thickness to variations can be determined in the material properties of the mould powders.     

METAL MATRIX PARTICULATE COMPOSITES BY SPRAYING CODEPOSITION

The spraying codeposition process is used to produce metal matrix paniculate composites, whose technical procedure and main processing parameters are analyzed. The microstructure of the composites is examined and the properties are tested. The solidification characteristics in the spraying deposition and solidification process are discussed. The results indicate that several problems involved in conventional methods can be overcome with this technique to preduce metal matrix paniculate composites. The reinforce particles are dispersed in the matrix homogeneously without solidification segregation. Compared with the matrix alloy,the composite proves to be harder and has excellent wear resistance.
