海事赔偿责任限制的法律适用

由于各国关于海事赔偿责任限制的法律规定不一样,因此,在涉外海事赔偿责任限制法律关系中就需要进行法律选择,以确定所应适用的法律。国际社会关于海事赔偿责任限制的法律适用主要有适用法院地法、适用侵权行为地法、适用船旗国法、适用最密切联系原则几种立法模式,中国《海商法》关于海事赔偿责任限制的法律适用宜规定为:海事赔偿责任限制适用船旗国法,若海事赔偿责任限制与其他国家的法律有更密切联系,则适用其他国家的法律。

Distribution of suspended sediment in the coastal sea off the Ganges–Brahmaputra River mouth: observation from TM data

Remote sensing technique was applied to estimate suspended sediment concentration (SSC) and to understand transportation, distribution and deposition of suspended sediment in the estuary and throughout the coastal sea, off the Ganges–Brahmaputra River mouth. During low river discharge period, zone of turbidity maximum is inferred in the estuary near the shore. SSC map shows that maximum SSC reaches 1050 mg/l in this period. Magnitude of SSC is mainly owing to resuspension of the bottom surface sediments induced by tidal currents flowing over shallow water depths. The influence of depth on resuspension is farther revealed from the distribution and magnitude of SSC along the head of Swatch of No Ground (SNG) submarine canyon. During high river discharge period, huge river outflow pushed the salt wedge and flashes away the suspended sediments in the coastal sea off the river mouth. Zone of turbidity maximum is inferred in the coastal water approximately within 5–10 m depth of water, where the maximum SSC reaches 1700 mg/l. In this period, huge fluvial input of the suspended sediments including the resuspended bottom sediments and the particles remaining in suspension for longer period of time since their initial entry control mainly the magnitude of SSC. In the estuary near the shore, seasonal variation in the magnitude of SSC is not evident. In the coastal sea (>5 m water depth), seasonal influence in the magnitude of SSC could be concluded from the discrepancy between SSC values of two different seasons. Transportation and deposition of suspended sediments also experiences seasonal variations. At present, suspended sediments are being accumulated on the shallow shelf (between 5 and 10 m water depth) in low discharge period and on the mid-shelf (between 10 and 75 m water depth) during high discharge period. An empirical (exponential) relationship was found between gradual settle down of suspended sediments in the coastal sea and its lateral distance from the turbidity maximum.     

基于层次灰色模型的铁路技术创新绩效综合评价

运用技术创新基本理论,结合铁路技术创新实际,从效益(经济、社会)增长、市场状态(市场份额、市场营销)改善和创新主体素质(技术装备水平、管理水平)提高3个方面建立了评价铁路技术创新绩效的多级指标体系。将层次分析法(AHP)和灰色系统理论结合起来建立了层次灰色评价模型(HGM),运用该模型对铁路技术创新绩效分别从整体和分项进行了综合评价,得出:铁路技术创新绩效绩优度为“一般”,其主要原因在于铁路运输市场状态改善中市场份额扩大程度较低。实证分析结果表明:改进层次灰色评价法(层次灰色评价模型)为一种评价铁路技术创新绩效的有效方法。
