浅析C语言中指针的应用

指针是C语言的精华部分,也是C语言课程的重点和难点章节之一,在C语言编程中起着重要的作用。只有理解了指针并能灵活运用指针,才算真正学会了C语言。因此我们在C语言教学过程中应特别注意指针,引导学生正确灵活地应用指针,编制高效的程序,发挥C语言的优势。

Black out cluster instrument

In recent years, the black out cluster with self-lit pointer has become increasingly popular, especially in the luxury car market and has earned a high reputation.In order to expand upon the above-mentioned technology for commercial vehicles we would like to report on a self-lit pointer (single chip LED type) having a reduced cost but performance equal to that of the conventional (multi-chip LED type).     

考虑转向延误的交通网络存储结构

城市路网中由于交叉口转向延误不可忽略,因此需要能够考虑转向延误的最短路径求解算法。传统的存储结构没有考虑转向延误,不再适应考虑延误后的新算法。在对比分析传统存储结构的基础上,通过引入新指针,对传统邻接链表结构进行了改进,使其能够高效率地实现节点延误的存储,并且给出了该结构的C 类模板实现方法。这些为交通管理规划实施事先评价和实现交通流诱导提供支持。

Les nouvelles donnes de la planification locale des transports en angleterre et en France

This paper deals with the new local transport planning instruments that have been developed in France and England. It describes procedures which have either been created (Local Transport Plans in England) or reactivated (Urban Travel Plans in France) on the basis of environmental issues. It also describes the manner in which the procedures have changed and the context within which both are applied. The comparative analysis approach shows the contrasts between the two countries. England, places an intermediate level, with extended powers and the legitimacy of universal suffrage, at the heart of a unified planning system which is, however, in competition with the local authority planning bodies set up in the 1980s. In France, on the other hand, the responsibility for Urban Travel Plans has been given to intercommunal bodies which are spatially restricted, politically fragile and in which the distribution of powers takes a vast variety of forms.     

基于通达和通畅指标的农村公路网评价

结合农村公路网建设与社会经济发展的相互关系,建立了有别于干线公路网评价的量化评价指标体系,评价指标分为两大类：一类是考查节点连接程度的通达性指标,另一类是考查路网道路交通条件的通畅性指标。在指标的具体设计中充分考虑到农村公路的基础数据相对缺乏的实际情况,从定性的视角出发,基于统计思想提出了如村镇通达方向、农村公路的经济吸引半径等技术指标,反映农村公路网建设的深度和广度。最后结合保定市农村公路网建设的现状,应用模糊综合评价方法进行了实例分析,取得较好的效果,证明了该评价体系的合理性,并指出了评价路网中现存的问题,为农村公路网的进一步规划提供了可靠依据。     

Gibraltar: le projet de lien fixe entre intégration euroméditerranéenne et développement régional

This paper presents a socioeconomic examination of the project for a fixed link in the Strait of Gibralter. This project for a major link between Europe and the Maghreb which would take the form of a rail tunnel can be examined at two different spatial scales, that of the major trade networks which link Europe and the Maghreb and that of the areas which are located near the future points of access to the tunnel. If we pass over the problems which may be posed by the financing of this project (which studies have shown to be profitable), the geopolitical context of changing relations within Europe and the Mediterranean should be favourable to its construction. Its strategic (and at the same time symbolic) character is defined by its role as a link between the trans-European networks and the southwestern shore of the Mediterranean basin. This physical connection may nevertheless generate undesired or even counterproductive effects in the directly exposed economies on the southern side. Additional strategies could be considered for which the existence of a tunnel would constitute an opportunity. These are referred to as accompanying measures in French regional planning policy.
