Abstract:小净距隧道是介于普通分离式双洞隧道和连拱隧道的一种结构形式，工程应用中它有以下特点：其造价和施工工艺同普通双洞隧道基本相似；与连拱隧道相比它的造价要低、施工工艺要简单；双洞间净距比较小，有利于公路整体线型规划和线型优化。基于上述因素，该结构形式很适合在短隧道的建设中。由于小净距隧道的中夹岩的厚度远比普通双洞隧道要小，隧道的围岩稳定与支护结构受力要比普通分离式隧道要复杂，所以需要从设计、施工、监理、监控量测等方面采取一定的措施来保证施工和营运安全。

Before compared with each other, the best value of all local minimum values can be found out, the value is thought as the global minimum in some degree. According to the method, a program is compiled and an example of design is implemented. The result of the example testifies that the method is feasible.

Abstract:Architecture market is a typical dynamic game market with incomplete information, in which exists three principal parts who are proprietors, supervising companies and contractors. There is a complex principal-agent relationship among them. With the analysis of the principal-agent relationship among proprietors, supervising companies and contractors, two dynamic games of incomplete information have been established and analyzed. If the proprietor only pay instant fee to supervising company, the supervising company will take weak supervise. Only with appropriate incentive way, the strong supervise can be done. Based on it, an incentive system is established to make the supervising companies and contractors work hard, to realize the given purpose of the proprietors.

Abstract:Stock prices are different on a daily basis with small ups, small downs, or abrupt changes. While small fluctuations are typical according to economic theory and understandable to most investors, abrupt changes are unexpected and can be either harmful (if dramatic downward change occurs) to a society's economy (and investors) or beneficial (if vast upward change occurs) to a society's economy (and investors). We introduce the variance change point model (volatility change point model), and use it to analyze two stocks: Shanghai Stock Composite Indices and Shenzhen Stock Composite Indices from 1992 to 2002. The authors use a binary procedure combined with Schwarz Information Criterion (SIC) as in Chen and Gupta (1997) to search all the possible variance (volatility) change points exist in the sequence. Changes in both indices are successfully identified and their economic explanations are given.

Abstract:In order to uncover the complex relation in the inventory data and lower the inventory level, based on the idea of black box method, all factors that influence demand are identified firstly. Then an initial forecast model of BP neural networks that adopt LM algorithm is established, and is trained using hospital inventory's history data. The interrelation's information of each factor that influences demand is stored in the link weights matrix W dispersedly. The final forecast model is obtained. We use the model to forecast the demand of medical equipment in Daping hospital. Based on it, the inventory cost is reduced enormously. The theory for the inventory system can be used to make management decision.

Abstract:International direct investment improved the world economic development greatly, and the level of capital transaction of a country indicates its degree of integration into world economy. In China, there exists a serious unbalance between outflow FDI (Foreign Direct Investment) and inflow FDI, and the former is of a extremely small scale. The relationship between outflow FDI and a country's economic development, as well as the relationship between outflow FDI and TFP (Total Factor Productivity) growth rate is analyzed with international comparison and econometrics model. The results show that a obvious positive correlation between outflow FDI and GNP exists, and outfolw FDI of a country improves its GNP growth a lot. Meanwhile, as to the contribution elasticity to TFP, outflwo FDI is much higher than international trade. It is revealed that China not only has necessities, but also has great potentialities to invest in foreign countries. Finally some suggestions are put forward.
