深圳市长途公路客运市场的现状思考

要想从根本上解决目前深圳市公路客运市场无序的问题,政府就必须下狠心、动真格的,对目前的公路客运市场动一次“大手术”;要从体制改革入手解决现有运营企业的多头管理、政企不分、站运不分等弊端,同时,加大运政监管力度,杜绝公路客运市场违规现象的发生。

“If I Walked on my Own at Night I Stuck to Well Lit Areas.” Gendered spaces and urban transport in 20th century Britain

Using photographs, this paper explores the gendered link between transport and the urban environment. It becomes apparent that moving around in urban spaces is an experience which is or can be fundamentally different for women and men. From pictures I conclude that a historical analysis of gender and urban transport ought to be a straightforward task to undertake: women are clearly visible in the visual record of the transport environment. However, a look at the historiography shows that research on gendering the city mostly deals with workplaces, women’s employment, class and race segregation in urban areas, welfare programmes specially designed to helped women, urban housing and marginalisation of women, housewives, healthcare, homeless women and politics. Gender and transport is hardly to be found: how women move and moved through urban space has not received sustained attention. Further, the main body of scholarly texts lacks in historical concern, stemming from such diverse disciplines as sociology, geography, economic and political sciences, women’s studies and planning.     

Competition in Brazilian bus and coach services - The results of recent competitive tendering processes

This paper analyses the terms and the results of a sample of some recent Brazilian bidding processes for the concession of public passenger transport services: namely, urban and metropolitan bus or regional coach services. The analysis is based on selected issues relating to competitiveness and upon the legal framework that applies in this sector. It was concluded that, given the lack of bidding processes for concessions in the bus and coach sector in Brazil, the fact that some bidding processes have been carried out should be considered a sign of progress. However, these auctions have not necessarily prioritised competitiveness, since many barriers to entry into the systems were imposed by the bidding terms. Future competitive tendering processes should seek to abide by stricter principles of competitiveness, if they wish to avoid the entire effort expended on conducting such processes serving only to mask nothing more than formal obedience to the law and to discredit the bidding process in the eyes of Brazilian citizens.

基于ADCP估算悬移质输沙率的应用研究

利用声学多普勒流速剖面仪（ADCP）的声反向散射强度（ABS）,估算悬移质浓度（SSC）的相关技术日臻成熟,其原理是利用走航式声学多普勒流速剖面仪（ADCP）,采集足够频次的流速和声反向散射强度,以替代流量和悬移质浓度（SSC）的数据,在一定程度上破解了在复杂水流环境中测定和估算水体悬移质输沙率的难题。简要介绍利用声学多普勒流速剖面仪（ADCP）估算悬移质输沙率的基本原理和方法,并结合在连云港徐圩海域水文观测中的应用实例,验证该方法的可行性、可靠性和精度。     

粗砂水力输送多峰阻力特性

提出了实验中发现的一种挖泥船管道水力输送粗砂阻力特性的新类型——多峰阻力特性,而现有理论根本无法解释这一现象。应用两层模型方法,对出现多峰阻力特性的管道水力输送粗砂实验数据进行了计算,分析了多峰阻力特性与内部流动分层结构的关系。研究表明,这种新型的多峰阻力特性的出现,是由于管道内部流动结构特性,如上下两层分界面位置、两层浓度差、速度差等,随着浆体水力输送平均速度的变化,出现了增减交替而非单调的变化。
