The distribution of euphausia snperba in the prydz bay region was very patchy , its abundance was higher in the slope area ( the pelagic area between the isobaths 1000 m and 3000 m ) than the open sea area ( the pelagic area beyond the 3000 m isobath ) 大磷虾在普里兹湾海区的分布呈斑块状。分布趋势是陆坡区(在1000和3000米等深线之间的海区)各站的丰度普遍大于深海区(大于3000米深度的海区)各站的丰度。
Since the contamination of the original water , the pollutant in the water such as organic substance , ammonia nitrogen , algae toxin , finally nitrate , pelagic microbe and so on , whose concentration and species are becoming higher and more , deteriorate the quality of drinking water seriously 由于水源受到污染，水中的有机物、氨氮和硝酸盐氮、藻类及毒素、浮游动物等污染物的含量和种类不断增多，严重影响了饮用水水质。
Against the problem , this thesis discusses how to develop a web information system for the pelagic ships and develop a web edis system in the lan of shipping corporation with the guidance of tenet that a few data be transmitted through the satellite 针对上述问题，本文利用在卫星链路传输少量数据，在客户端进行web页面重组的思想论述了如何面向远洋船舶建立web信息服务系统以及如何在航运企业局域网中建立动态船位webedis (电子海图)系统。
The main purpose of our paper is to build the coupling pelagic - benthic one - dimensional box model for yscwm , and use it to study the seasonal variability of the vertical structure of each variables , energy flow characteristics , the contribution of microbial loop and the income and expenses of nutrient elements of the ecosystem in this region 本文的主要研究目标是构建黄海冷水团水域水层-底栖耦合生态系统垂直一维模型，并利用此模型对该海域生态系统各生态变量垂向结构的季节变化特征、物流能流结构特征以及微食物环的贡献和营养盐的收支循环等问题进行动力学研究。
But in the field of sea transportation , asp is delayed because of the limit of bandwith of satellite communications . the bulky edis data cannot be transmitted through satellite and the pelagic ships cannot take the service from internet through satellite based on the cost of satellite transmission 但是对于海事领域，由于卫星链路的带宽限制，使得asp信息平台在船舶和陆地之间不可能传输较大的电子海图数据；同时从费用方面考虑，船舶也不可能通过卫星链路访问internet 。
The vertical flux between compartments of the model system is also taken into account . basic characteristics of the seasonal variations of the pelagic - benthic coupling ecosystem in the yscmw are simulated . compared with the observations and the related studies in this region , it is found that the seasonal cycle of ecosystem is well represented and the relationships between variations and different layers are acceptable 通过该模型对黄海冷水团水域生态系统各生态变量的季节变化进行了模拟，并同黄海冷水团水域的观测资料及相关文献分析对照，证明模拟结果能较好地反映出黄海冷水团水域生态系统的季节变化特征，各个生态变量间的关系及不同水层间的生态变化差异是比较合理的。
