湖南省工业集聚的空间关联性研究

湖南省各市州的工业总产值之间在空间上存在相关性,工业发展水平相近的市域有显著的集聚特性,但不同地区集聚程度存在显著差异。长株潭是我省工业发展的核心增长极,也是工业发展的热点区域;湘南部分地区和湘西地区是全省工业发展的“凹地”,处于工业集聚的边缘地带;工业发展的冷点区则集中在西北的市州。湖南省未来工业空间集聚格局,应该以长株潭为核心集聚区域,以连接长株潭与四大次级增长圈的交通道路和经济成长带为轴线,逐步向周边拓展,从而形成圈层状工业空间集聚结构。     

Financial information management for university departments,using open-source software

This paper presents a model to analyse the different outcomes generated by the application of Task-Technology Fit (TTF) theory to economic and financial information management in university departments. This model extends that proposed by Goodhue (1995), in two ways: (i) a key role is played by the manager in designing the technology and in performing the task in question. Both of these aspects can be modified, depending on the evaluation made of a series of characteristics (or dimensions) inherent to the model. (ii) The free dissemination of the source code of the application not only allows the transfer of knowledge, but also creates virtual communities which, through collaborative work and the exchange of experiences, can achieve a better fit of the technology to the task at hand. This model has been introduced in several departments at the University of Granada (Spain), and evaluated in terms of the results obtained at both individual and group levels. This evaluation was conducted by means of in-depth interviews with departmental managers.

京津冀地区城市客运交通碳减排政策的成本效益分析

客运交通在京津冀地区城市交通总量中占比高,其减排潜力是影响交通碳达峰的关键因素。本文建立了基于Agent建模与仿真方法的京津冀地区城市客运交通系统的模型,模拟了京津冀地区不同城市客运交通碳减排政策情景下消费者的交通出行行为,评估了各类碳减排政策的环境效益、经济成本及其对碳达峰的影响。结果显示：①乘用车燃料效能提升政策是唯一可以在2030年京津冀三地同时实现城市客运交通碳排放达峰的政策情景,且其碳减排的经济成本较低,其中天津市预计最先实现碳排放达峰,北京市次之,河北省最后;②公共交通推广政策的碳减排经济成本相对较高,尤其以河北省最为突出,虽然该政策可以在北京市和河北省实现城市客运交通碳排放达峰,但无法实现天津市碳排放达峰目标;③交通拥堵收费政策在京津冀三地单独实施无法实现碳排放达峰目标,需要与其他政策组合实施。基于此,京津冀三地实现客运交通碳排放达峰目标需要持续推进乘用车燃料效能的提升,此外还可以采取新能源汽车补贴、公共交通推广和交通拥堵收费等组合政策,以降低减排的经济成本。

Chinese archaeological artefacts: Microstructure and corrosion behaviour of high-leaded bronzes

Metallographic features of ancient bronze artefacts often hide peculiar micro-chemical processes and corrosion behaviours, which are worth to be studied as they can provide conservators and archaeologists with valuable tools and information. It is widely documented that Chinese bronzes were cast and the way to adjust their properties was to change the alloy composition. In particular, addition of lead, which is insoluble in the bronze matrix, results in the formation of inclusions or globules, which undergo oxidation processes leading to their conversion into corrosion products. The mechanisms through which this occurs were still poorly investigated. The present work was conducted to further study the corrosion behaviour of high-leaded bronze, especially focusing on the behaviour of lead globules. To this aim, a collection of Chinese archaeological bronzes, showing intermediate steps of degradation, were selected and investigated. The use of combined microscopy-based, molecular and elemental, analytical techniques allowed the characterization as well as the precise location of corrosion products, thus enabling us to propose a degradation pathway basing on thermodynamic data provided by Pourbaix diagram. The achieved results will be useful for researchers involved in these kinds of studies to better interpret data obtained.     

跨世纪河北对外开放的若干战略性问题

〕河北省２０年来的对外开放虽然取得了很大的成就，但与东南沿海省份相比仍有不小的差距，如何构建与完善跨世纪的河北省对外开放战略显得尤为重要。以环渤海经济发展战略为突破口，全面构建河北的对外开放战略乃是重之中重；另外还要注重发展省际协作，强化利用外资的力度，深化外贸体制改革，使河北省的经济发展再上一个台阶     

The impact of electric overhead radiant heating on the indoor environment of historic churches

The impact of electric overhead radiant heaters on the microclimate, air flows, transport and deposition of suspended particulate matter (SPM) was monitored between March 2004 and March 2005 in the historic churches of Saint Michael Archangel in Szalowa and Saint Catherine in Cracow (Poland). The measurements show that although irradiation at the floor level increases temperature and reduces relative humidity in the interior of the church, the effect out of the heated zone and for the surfaces sheltered from irradiation is very limited, i.e. their extent is comparable with natural fluctuations inherent to the local climate of the church. The radiant heaters proved to generate little convectional flow of the air. Therefore, the heating system was not found to increase the concentration of SPM indoors; in particular, no re-suspension of particles already present in the church was observed. This work has demonstrated that the overhead radiant heaters are capable of providing localised heat to the areas where people congregate without adversely affecting painted walls and the works of arts displayed in churches. Care, however, should be taken that sensitive works of art are not exposed to the direct infrared radiation.
