The research of this thesis is under the circumstances that the international shipping center of Shanghai builds Yangshan deep water port project, first of all, through its SWOT analytical method analyze Shanghai maritime affairs situation, maritime affairs office existing boat policy, Yangshan deep water port hydrometeorological situation, analyze the present main ship type, to explain the background of the choice the ship the small waterline, to put forward the necessity of building small water-plane area twin hull maritime affairs patrol ships. Then, it introduces the principle, characteristic of the small waterline, and has analyzed the domestic and international state of development of the SWATH ship, and conclude that it is feasible to build SWATH maritime affairs patrol ship technical, through the research and analyze of design at home and abroad,; Then it analyzed the application of the SWATH ship in maritime affairs manage both at home and abroad, put forward the preliminary scheme, and carry on research to the economic performance of technology of the scheme, through putting forward the preliminary model of plan of design to main yardstick and selecting type of host computer finally after relatively optimize, and confirm design specifications .

本文的研究是在上海国际航运中心建设核心工程洋山深水港的大前提下，首先，通过利用SWOT分析方法分析了上海海事局面临的形势，对上海海事局现有航政管理船舶现状进行分析，对洋山深水港海域的水文气象情况进行了调研，对当前主要船型进行分析，对选择小水线面船的背景加以阐述，提出建设小水线面双体海事巡逻船的必要性：接着，对小水线面船的原理、特点加以介绍，并对小水线面船国内外发展状况进行了分析，对国内设计建造小水线面双体海事巡逻船的技术可行性进行了研究分析，得出国内设计建造小水线面双体巡逻船在技术上是可行的；然后对国内外应用于海事管理等工作的小水线面船型进行分析，提出初步的方案，并对方案的技术经济性能进行研究，通过对主尺度和主机选型等进行比较优化后最终提出初步的设计方案模型，并确定设计任务书。

Based on the rolling test results of five catamaran models with symmetrical demihulls in the smooth water, when the linear and square dampings are considered, the reduced amplitude coefficients and nondimensional rolling added moment of mass inertia are discussed.

根据5条具有对称片体的双体船模型在静水中横摇试验资料，讨论了双体船横摇附连质量惯性矩系数，线性阻尼以及纯平方规律阻尼下的减幅系数与船型参数的关系。

The oligomeric states of PSⅡcomplex in soybean leaves treated with moderate light (700μmol〓) and strong light (2000μmol〓) were studied by nondenaturing PAGE and gel filtration chromatography. The following results were obtained. PSⅡ dimers resolved by nondenaturing PAGE accounted for about 75% of total PSⅡ complexes and there was no significant difference in the ratio of PSⅡ dimer to monomer between samples from moderate light-treated and fully dark-adapted leaves.

利用非变性聚丙烯酰胺凝胶电泳方法分离PSⅡ双体和单体，结果表明PSⅡ双体约占总PSⅡ含量的75％，并且经中等光（700μmol m〓）处理后，大豆叶片PSⅡ单体/双体比例没有明显变化。

Finally, analyse the calculated results of this ship with another catamarans. From this result obtained unsymmetrical catamaran hull of this particular special vibration mode and analyse the vibration mode in order. The calculation is fairly reasonable, for the future of the asymmetric catamarans to calculate the vibration analysis of a number of reference.

最后将本船计算结果与另一艘双体船计算结果进行了比较分析，得到不对称双体船这种特殊船型的特殊振动模态，并就其振动模态出现次序进行了比较分析，说明本次计算是比较合理的，为今后不对称双体船的振动特性分析计算提供了一些的参考。
