- 摘要：To develop the public traffic and setup a city form coordinated with the development of the public traffic has become a common sense in the full achievement of the city sustainable development. Due to the particularity of the exploration procedure and some difficulties in urban development, the policy on developing public traffic has not been realized in our country. Now it is on edge to solve these problems, particularly in the new area of development. In this article, the authors intend to find a practical way of establishing a ciity development mode with adapting the public traffic development by contrasting Lujiazui new area in Shanghai and the new east area in Chongqing.602|16|0更新时间：2023-11-28
- 摘要：Owing to the special geographic environment and chronic historical accumulation,the Chinese nation has formed the national character mainly based on "renaissance ideology",which has exerted a profound influence on the forming and development of Chinese traditional architecture.By discussing the spatial pattern characteristics of country,cities,courtyards and geomantic omen,the authors indicate their common feature-enclosure,and summarize the spatial pattern of Chinese traditional architecture influenced by "renaissance ideology"-layer upon layer enclosure by bringing the spatial patterns of different layers into a unified framework.At the same time,the construction activity is extended to social culture so as to find out the correlation between the spatial pattern of Chinese traditional architecture and national character.751|1163|0更新时间：2023-11-28

- 摘要：Monolayer cable net system for point - supported glass facade is a kind of flexible tension structures with relatively strong nonlinearity. Its stiffness greatly depends on the pretension in cables. Yet there are few literatures at present reported on its dynamic properties. The characteristic of modal analysis for flexible pre - stressed structures such as cable structures is expatiated herein. Corresponding program was developed to analyze two important factors such as pretension and geometric nonlinearity for dynamic behaviors of cable net herein. It is demonstrated that large errors are brought about by omitting nonlinearity. There exists apparent nonlinear relationship between vibration frequency and pretension in cables. The influence of pretension and geometric nonlinearity on the dynamic properties of cable net is in coordination with each other.468|713|0更新时间：2023-11-28

- 摘要：For designing a reasonable housing supply system for the civil servants,the sorted Multinomial Logistic Model is adopted to appraise the match-up level of current housing supply policy and the actual housing demand of the civil servants.Those unmarried,on department level and below,discontented with current housing subsidy method,or those who acquired their houses from the non-market source are likely unsatisfied with the current housing conditions.The result of the Unsorted Multinomial Logistic Model identifies the housing affordability and the housing subsidy standard as the key factors to affect the housing choice of the civil servants.The supply sources,the housing modes for the special civil servants group and the subsidy standards should be focused on when constructing the whole civil servant housing supply policy system.339|448|0更新时间：2023-11-28

- 摘要：To study on how to choose the optimal capital structure for financial distressed listed firms,the difference of the factors influencing the capital structure and the adjusting procedure between non-distressed firms and distressed firms is analyzed.It shows that the high debt ratio of the distressed firms is significantly related with the proportion of the largest shareholder and the concentration of the share structure.However,the proportion of largest shareholder has little effect on the adjustment of capital structure.Therefore,to solve the problem of distressed firms,it will depend not only on the improvement of corporate governance,but also on the optimization of financial channels.503|9|0更新时间：2023-11-28
- 摘要：The interest of the parties in construction industry is detached under the traditional contracting model.Non-cooperation,malignant competition and suits bring on high exchange cost,wasting of resources and higher risks.As a new contracting model,relational contract aggregates all parties' interest objective and circulates under a flexible agreement frame.It includes Partnering,Alliance,Long-term Contract and Joint-Venturing with their own characters and merits.This paper analyzed the obstacles of applying relational contract in practice in China and puts forward the corresponding countermeasures.413|11|0更新时间：2023-11-28
- 摘要：Two problems often appear in estate auction.The first is to whom the buyer can claim cancellation of the contract,if he can't get the estate.The second is whether the tenant can still claim his priority to the estate.In auction,we can't use the principle of agency,fiduciary and mediation to explain the relations among client,auctioneer and buyer,because it doesn't accord with the auction practices and the Action Law section 40.The undisclosed agency in Contract Law may be an adapt explanation to the relations.According to the law hermeneutic,we should narrow the scopes of the tenant priority and exclude it from auction.528|14|0更新时间：2023-11-28
