加强行业管理 繁荣台州港口

<正>近年来,台州港务局根据港口市场由计划模式逐步向市场模式过渡出现的新的情况,在港口行业管理上实行了三个转变:即由过去的主要为公用码头服务向为全港各专用码头服务转变;由过去的收费管理型向现在的管理服务型转变;由过去的单纯为海门港服务向为台州港（包括海门、大麦屿、健跳港）服务转变;收到了一定的效果。 一、建章立法,依法行政 随着经济体制改革的深入,台州地区港口市场也出现了一些新的情况:一是货主专用码头越来越多,大大超过公用码头发展的速度。“七五”、“八五”期间,海门港公用泊位增加了两个,而货主专用泊位却增加21个。其中千吨级以上的有4个。二是货主专用码头吞吐量也越来越大,大大超过了公用码头的吞吐量。“七五”期末,海门港公用和货主专用码头吞吐量之比是1:3,到了去年达到了1:3.7。三是码头的经济成份多样     

武汉港林四房港区龙口煤炭码头吞吐量研究

湖北省目前承担煤炭运输的港口主要为武汉港、宜昌港、襄阳港及荆州港。武汉港煤炭码头主要分布在沌口、杨泗、舵落口港区。武汉港是长江＂三口一枝＂煤炭中转港口之一,主要通过京广线、京九线和汉丹线承担河南、陕西、山西等调往长江中下游的煤炭中转任务。武汉港目前从事煤炭运输的港区主要有杨泗港区、沌口港区和舵落口港区。由于受土地资源和环境容量的制约,现有港区煤码头处于城市中心,吨级不高、设施陈旧、陆域狭窄、污染严重,已经没有发展空间和环境;同时,随着地方经济社会发展和城市化进程加快,规划将现有煤炭码头迁出城区。

Synoptic transects on the distribution of trace elements (Hg,Pb, Cd,Cu, Ni,Zn, Co,Mn, Fe,and Al) in surface waters of the Northern- and Southern East Atlantic

Surface seawater samples were taken in the framework of the GEOTRACES program on “POLARSTERN” expedition ANT XXIII/1 in the Eastern Atlantic in 2005 to study the distribution of the trace elements Hg (mercury), Pb (lead), Cd (cadmium), Cu (copper), Ni (nickel), Zn (zinc), Co (cobalt), Mn (manganese), Fe (iron), and Al (aluminium). With the exception of Hg, results were compared to earlier datasets from 1989 to 1990. The particulate fraction averaged over the transect was calculated to be 49% for Cd, 23% for Mn and 50% for Fe indicating a release of these TEI's (trace elements and their isotopes) from a leachable SPM fraction in the stored and acidified samples.Total Pb concentrations ranged between 5 and 20 pmol kg^? 1 in 2005 with highest values in the ITCZ (intertropical convergence zone). In 1989 Pb concentrations were twice as high in the region of the ITCZ, while by a factor of 10–15 higher values were obtained in the North Atlantic.Total Cd and Co are dominated, by different seasonal upwelling regimes (Equatorial upwelling, Guinea Dome, Angola Dome).Total Cu, Ni, Fe, Mn and Al show nearly identical concentrations in 1990 and 2005. For total manganese and aluminium strong maxima (3–4 nmol kg^? 1 and 55 nmol kg^? 1 respectively) are observed between 23°N and 0°, while the Fe maximum (6–9 nmol kg^? 1) is located at 7°N. Total Hg concentrations ranged between 0.5 and 4.5 pmol kg^? 1.     

球扁钢等效方法的研究

在进行船体结构强度的计算分析时,需要将球扁钢等效为L型材或T型材进行屈服及屈曲计算。然而,现有的等效转化方法存在较为明显的问题。本文在前人研究基础上,推出两种简化等效方法,并与现有方法进行计算对比,结果表明这两种方法简单方便,精确度高。此外,本文分别使用三种转化方法,运用Mars2000软件计算某船剖面的极限强度。计算结果表明,使用本文提出的等效转化方法一计算船体结构极限强度最合理。

Monitoring trace elements (Al, As, Cr, Cu, Fe, Mn, Ni and Zn) in deep and surface waters of the estuary of the Nerbioi-Ibaizabal River (Bay of Biscay, Basque Country)

Deep water samples (in contact with the sediment) were collected at eight different points of the estuary of the Nerbioi-Ibaizabal River (Bay of Biscay, Basque Country), both at low and high tides, during four sampling campaigns (May, September and December 2005 and March 2006). Superficial water was also sampled in March 2006. Temperature, pH, redox potential, dissolved oxygen and electrical conductivity corresponding to each sample were measured in situ at each sampling point using a multiparametric probe. The physico-chemical parameters found are typical of highly stratified estuaries, with an acceptable oxygenation level. After filtering and acidifying the samples, they were analysed by inductively coupled plasma/mass spectrometry (ICP/MS) to simultaneously determine the total concentration of Al, As, Cr, Cu, Fe, Mn, Ni and Zn. Concentrations in the μg kg^− 1 level were found in all cases (c_Cr and c_Ni, 1–10; c_Al, c_As and c_Zn, 10–50; c_Cu and c_Mn, 10–100 and c_Fe, 100–400 μg kg^− 1). A probable net input of Al, Cr, Mn and Zn via the main (Nerbioi-Ibaizabal) and some of the tributary rivers (Galindo, Asua and Gobela) was identified. Evidence of a common source of Al and Zn to the estuary was found. Correlation analysis of data revealed connections between variables (concentration of Cu, Fe and As with salinity, as well as c_Al with c_Zn, c_Cu with c_Fe, c_As with c_Fe, and c_As with c_Cu). Principal Component Analysis (PCA) of data allowed the samples to be grouped according to sampling campaign, with two principal components accounting for 62% of the total variance. In addition, plots of element concentration against salinity suggested a conservative behaviour for As, Cu and Fe and a non-conservative one for Cr. Not clear mixing behaviour was observed for the rest of elements.

Specialization and economic impact of the ports of Montreal,Quebec, Saint John,and Halifax

Specialization in cargoes and forelands is defined for the ports of Montreal, Quebec, Saint John, and Halifax using a variation of the location quotient. Economic impact is also defined using the location quotient. All ports are shown to have some degree of specialization; whereas, Saint John and Halifax have relatively greater economic impact. It is suggested that the four ports should be encouraged to develop their specializations. However, are the benefits to the shipping industry in following such a policy outweighed by the losses to the local economies because investment in certain ports does not take place?

FOB、CIF、CFR与FCA、CIP、CPT价格术语在运输方式、风险转移点、提单签发人、时间、地点、性质及运费计收、保险区段、运输合同订立等方面存在差异,国际商会自上世纪20年代起即不断对有关价格术语进行研究和解释.但由于国际贸易、运输的发展,人们对新、老价格术语中买卖双方的风险转移、责任、费用的划分时常难以理解.本文中作者试通过案例分析说明之.     

刚果(布)黑角矿业港总平面布置

针对复杂水动力环境条件下港口平面布置,基于刚果(布)黑角矿业港项目,根据对波浪、海流以及泥沙等主要影响因素的深入分析,提出两个平面方案,并通过方案比选及模型试验研究,采用对周边水动力环境影响小、易于起步、投资回报高的单侧防波堤疏浚土回填造地的双港池平面布置方案。结果表明,对于受复杂水动力影响的刚果(布)及临近海域港区的平面布置,应重点考虑波浪的掩护、沿岸输沙以及波浪和海流对船舶的共同影响。
