- 摘要：This paper discusses practical methods of investment risk analysis at a construction project,applying the Xifang Economics Principle and the Mathematical statistics etc, It has reference value for improving the Feasibility Research(FR)and Investment Decisions.597|10|0更新时间：2023-11-28
- 摘要：Concerning the existent and latent risk in building,operating and transfering of BOT project, the model of BOT risk is advanced in AHP way, and on the basis of sinqle target and the importance of the weiqht of each index affecting,the policy in the risk of the BOT project is made by the use of the method.454|609|0更新时间：2023-11-28
- 摘要：A new type of tube settler with rectangular cross-section and vertical adhesive interface in the tube module is proposed.The tube module by this kind of tube settler has flat top and bottom faces.Experiments show that the tube settler with rectangular vross-section and vertical adhesive interface has the advantages of better sedimentation performance,less material censumption for its construction and no flow transitional section from turbulent flow to laminar flow in the inlet part of the tube of which the whole length takes part in solid-liquid separation.595|505|0更新时间：2023-11-28

- 摘要：The thesis studies the cooling method using the porous-moist material covering on exterior surface by the passive solar evaporation.The mathematical Model for the process of heat and moisture transfer based on the moist-porous material under passive solar vaporization cooling is established. Through theoretical analysis.computer simulation and test measurement in situ, all results show the law of the thermal process. It is said that this method is feasible.1017|743|0更新时间：2023-11-28
- 摘要：Guan Zhong was an outstanding statesman and thinker in the early ages of the Spring and Autumn Period.His masterpiece,Guan Zi,gave a detailed illustration on his thoughts.By enganing in the study of Guan Zi,I would like to introduce my views on Guan Zhong's thoughts of city construction, which include city function, classification. density, selection of site, form,arrangement, flood prevention etc.In the article, it is clearly shown that Guan Zhong was the first person who expounded the theory of city construction scientifically and systematically in the history, and made a big contribution to the city construction of ancient China.Guan Zhong was the master of ancient Chinese city planning and construction.974|985|0更新时间：2023-11-28
- 摘要：This paper discusses the necessity and significance of developing the extra fine-complex sway jaw crusher.It should be pointed out that you wlill have a success if you adopt the methods of the optimization design.Also it recommends the methods, steps and flow chart of the optimization design of the extra fine-complex sway jaw crusher.And it discusses the grading charts of the particulate products crushed by these two kinds of the etra fine-complex sway jaw crushers developed.689|686|0更新时间：2023-11-28
- 摘要：In this paper,in terms of the measured data(including the deflection and slope at the ground surface of the pile,the maximum bending moment and its position),the biparameter method is used to analyze the pile-soil parameters.Two examples show that the method in present paper is reasonable and reliable,and it provides the reference value for the engineering design.431|623|0更新时间：2023-11-28

- 摘要：This paper recommends a method of lowering the ground water table by setting up the horizontal drains in hill slopes.Based on the finite element analysis, the method advances the experiential formulation about the downstream water depth of the horizontal drains and the distance between the horizontal drains. The experimental result seems to agree reasonably well with the expression.So, in engineering practices,the formulation can be used to predict the amount of lowering of the downstream water depth, and also to confirm the distance between the horizontal drains.423|689|0更新时间：2023-11-28
