动态网页制作及ASP技术应用

ASP作为目前一种比较成熟的服务器端脚本编写环境,在网页制作中得到广泛的应用。ASP结合ADO能快速地实现对数据库的访问。本文介绍了ASP同数据库建立连接的两种方法,一种是通过OLE DB连接ODBC驱动程序,在ODBC的系统DSN中指定数据源进行连接;另一种是通过快速的OLE DB Provider技术连接数据库;同时介绍了动态网页分页功能的实现方法,增强了页面的可视化效果,实现了页面间的快速跳转,方便查询。

房地产融资渠道分析

由于国家银根收缩，房地产融资难度增大，加上中国房地产金融体系尚未完善，融资渠道狭窄，在一定程度上限制了我国房地产业的发展。房地产业需要新的融资渠道，如信托、基金、债券等取代传统的银行贷款融资模式。针对新的市场现状，各房地产企业必须加强资本运作能力，扩大融资渠道，创新金融产品。     

Managing and financing metropolitan public services in China: experience of the Pearl River Delta region

Under China’s current fiscal policies and inter-governmental relations, it is a significant challenge to finance and deliver public services across jurisdictions. This challenge was met in the Pearl River Delta region in southern China with a collaborative governance approach. Directives from higher-level governments and horizontal inter-city fiscal arrangements were successfully combined to deliver public services. Effective networks should be developed to improve co-ordination and collaboration in delivering cross-jurisdictional public services.

A TVD SCHEME FOR INCOMPRESSIBLE FLOW COUPLED WITH DIFFERENT TURBULENCE MODLES ON A GROUND- MOUNTED SQUARE-RIB FLOW

A finite-difference Total Variation Diminishing (TVD) numerical simulation model for coupling the Reynolds Averaged Navier-Stokes (RANS) equations, pressure-relative continuity equation and various k-εturbulence models was developed to solve the incompressible flow based on the pseudo-compressibility method. The hyperbolicity of all these equations was studied and the discretization of the fully coupling equations with all the primal variables and source terms were made in this article. Numerical simulation for modeling the flow around a ground-mounted square rib was implemented and validated by comparing with the published wind tunnel experimental data. It is shown that such a numerical simulation method with a proper turbulence model has a very good accuracy to simulate the flow around a surface-mounted rib. It is concluded that the Renormalization Group (RNG) and Chen-Kim k-εturbulence models have much better ability to predict the characteristics of the vortex structure and flow separation than the standard k-εmodel.     

中国省区工业产业专业化程度实证研究:1988～2002

本文通过构造产业地方专业化基尼系数,利用工业产业增加值数据,直接测算从1988年到2002年每个省区的工业产业专业化水平,发现我国省区产业结构出现了“两头高,中间低”的格局。根据各个省区十几年的地方专业化基尼系数的整体变化趋势,把省区划分为降低型、U型、增高型和大致不变型,并发现中西部的专业化程度提高,而东部大部分省区的产业结构经历了一个调整的过程,地方专业化基尼系数先降低,之后有些发达省份又有所提高。
