地理信息档案管理的探讨

随着现代科学信息技术迅猛发展和广泛应用,我国测绘业已基本实现由传统模拟测绘技术体系向数字化、信息化测绘技术体系的跨越.地理信息是一种以采集、贮存、管理、分析和描述整个或部分地球表面空间地理分布有关数据的空间信息,已广泛应用于交通、电力、水利、农林、国土资源、环境保护、金融、电信、地质、矿产、城市建设、教育、人口、海洋以及军事等几十个领域.     

德国劳氏船级社在中国

法国船级社(BV)收购德国劳氏船级社(GL)已落下帷幕,收购失败.BV首席执行官曾强调,GL如果与BV合并,两大船级社将在世界各大船级社等机构中占据领先地位,这一地位在亚洲显得至关重要,大量投资将流向亚洲尤其是中国,以满足快速发展的船舶业市场.但是,GL汉堡总部对提高地位这一说法并不信服,因为自1994以来,GL已经在中国取得了稳固的市场地位,现在中国有50多家船厂已经拿到了超过350艘集装箱船、多功能船、散货船、油轮和化学品船的订单,而客户们信赖GL的质量保证、快速批准计划和可靠的技术支持.     

理念精神舆论——关于交通软实力建设的思考

党的十七大文件中第一次提到国家软实力问题。完成中华民族的伟大复兴，在于综合国力的全面提升，而综合国力既包括由经济、科技、军事实力等表现出来的“硬实力”，也包括以文化、意识形态吸引力体现出来的“软实力”。行业软实力是指一个行业以其自身的地位、作用和形象对社会产生的影响力、对公众产生的吸引力和对其他行业产生的仿效力。概括地讲，行业“软实力”包括三个要素，即理念先导力、精神感召力和舆论引导力，其中理念是先导，精神是动力，舆论是环境。     

真的"猛士"和真正的"大人物"

公元前200多年,中国历史上演了有名的一幕:楚汉之争. 当时的情况是楚强汉弱,汉王刘邦连连吃败仗.可是刘邦是块牛皮糖、是个不倒翁,败了就逃,逃了又兜个圈子转回来,再打.楚王项羽受不了,对刘邦说:"不如我们一对一单挑,决个雌雄罢,免得天下百姓再为你我二人白白受苦了!"(愿与王独身挑战,以决雌雄,毋徒令天下父子为也.)刘邦笑了笑,答道:"吾宁斗智,不愿斗力."结果,力能拔山、气可盖世的楚霸王项羽,就这样慢慢被刘邦"耗"死了--流氓出身的刘邦成了汉高祖.     

采用沿岸动力概念以减少埃及红海海域高速船燃料消耗与降低排放(英文)

The progress of economic globalization,the rapid growth of international trade,and the maritime transportation has played an increasingly significant role in the international supply chain.As a result,worldwide seaports have suffered from a central problem,which appears in the form of massive amounts of fuel consumed and exhaust gas fumes emitted from the ships while berthed.Many ports have taken the necessary precautions to overcome this problem,while others still suffer due to the presence of technical and financial constraints.In this paper,the barriers,interconnection standards,rules,regulations,power sources,and economic and environmental analysis related to ships,shore-side power were studied in efforts to find a solution to overcome his problem.As a case study,this paper investigates the practicability,costs and benefits of switching from onboard ship auxiliary engines to shore-side power connection for high-speed crafts called Alkahera while berthed at the port of Safaga,Egypt.The results provide the national electricity grid concept as the best economical selection with 49.03 percent of annual cost saving.Moreover,environmentally,it could achieve an annual reduction in exhaust gas emissions of CO2,CO,NOx,P.M,and SO2by 276,2.32,18.87,0.825 and 3.84 tons,respectively.     

Bucket Group Effect of the Composite Multi-bucket Structure

As a novel type of foundation in beach and shallow sea,the bucket structure is especially suitable for complex conditionssuch as soft clay ground and the worse types of sea environments.In this paper, the bearing capacity of a multi-bucket structure isstudied by experiments with a single bucket and four-bucketfoundation in a saturated sand layer. Based on the experimentaldata and numerical analysis results, the bearing capacity behaviorand the bucket group effect are compared and analyzed.Furthermore, some influential factors, such as the soil type, theratio of length to diameter L/D, the ratio of the bucket spacing tothe bucket diameter S/D, and the bucket number are introduced andtheir effects on the multi-bucket structural capacity are investigatedThe vertical static capacity adjustment factor is introduced toevaluate the bucket group effects of the multi-bucket foundation.

有限水深中垂直下潜弹性薄板的水波散射(英文)

The problem of water wave scattering by a thin vertical elastic plate submerged in uniform finite depth water is investigated here.The boundary condition on the elastic plate is derived from the Bernoulli-Euler equation of motion satisfied by the plate.Using the Green’s function technique,from this boundary condition,the normal velocity of the plate is expressed in terms of the difference between the velocity potentials(unknown)across the plate.The two ends of the plate are either clamped or free.The reflection and transmission coefficients are obtained in terms of the integrals’involving combinations of the unknown velocity potential on the two sides of the plate,which satisfy three simultaneous integral equations and are solved numerically.These coefficients are computed numerically for various values of different parameters and depicted graphically against the wave number in a number of figures.

Community-Based Management for Sustainable Fisheries Resources in Phang-nga Bay,Thailand

Fishing communities, the Government of Thailand Department of Fisheries, local nongovermnental organizations, universities, the Food and Agriculture Organization of the United Nations (FAO), and FAO's Bay of Bengal Program have undertaken a partnership in management of Phang-nga Bay's coastal resources. It is the first project of its kind in Thailand, and although still in the early stages, offers insights that may contribute to our knowledge of how we can improve our management of coastal resources, including the importance of (1) building relationships within the governance process; (2) combining education, enforcement, and economic incentives to achieve compliance; (3) implementing solutions early; and (4) government support of community-based decisions. These insights reinforce trends emerging in other coastal management projects in the Asian region.     

Catalyzing Coastal Management in Kenya and Zanzibar: Building Capacity and Commitment

Site-based projects were initiated in Chawka Bay-Paje, Zanzibar, and Nyali-Bamburi-Shanzu, Kenya, to demonstrate the benefits of an integrated coastal management (ICM) approach for addressing coastal issues such as tourism development and enhancement of resource-dependent village economies in eastern Africa. A two-year, multidonor project used three primary strategies to make rapid, but sustainable, progress toward ICM. These included using interagency government teams for ICM planning, adopting an internationally recognized framework for ICM as a project ''road map,'' and explicitly incorporating capacity-building strategies into all aspects of the project. Within two years, integrated ICM action strategies, prepared through participatory processes, were being implemented at both sites, and both teams were working to expand the scale and scope of ICM in their nation. More importantly, the project helped create committed, capable, interagency groups that continue to work together to address urgent ICM issues.

船长与引航员关系的法律分析

在船长与引航员的法律关系上,存在一些比较流行的观点和看法,却未必经得起法律思考,缺乏一定的法律依据。将《劳动法》、《合同法》、《海商法》、《船舶引航管理规定》等法律、法规和部门的规章作为依据,从法律的角度分析船长在实际工作中遇到的问题,使船长从法律的高度正确认识船长与引航员的关系,有利于船长与引航员之间关系的认识和处理,达到驾驶台团队的和谐、驾驶台资源的充分利用,进而达到增强和改善港内引航安全,做好船舶安全管理工作的目的,同时也为了避免或减少在实践中造成行政违法行为的发生。
