斑节对虾(Penaeus monodon)蛋白质的氨基酸分析

１９９３年分析了不同大小斑节对虾肌肉中游离氨基酸含量和肌肉蛋白质 的氨基酸组成。虾体肌肉中有各种游离氨基酸存在，但数量很少，而且比例与肌肉 中结合氨基酸不一致。不同大小斑节对虾，其肌肉中氨基酸组成基本一样，不同的 是小虾的半胱氨酸、蛋氨酸含量比中虾、成虾的低；成虾的缬氨酸、异亮氨酸含量比 小虾、中虾的低，而酪氨酸、苯丙氨酸、天门冬氨酸较高。随着虾体的长大，甘氨酸、 丙氨酸的含量逐渐下降，而脯氨酸的含量升高。雌雄虾的氨基酸组成基本一致，只 是雄虾的甘氨酸含量偏低，精氨酸含量偏高。     

Wave-Current Forces on Small Square Cylinders (Part I)

-Based on the extended Morison Equation and model tests, the in-line forces on small square cylinders caused by waves (regular and irregular) and currents are analyzed in detail in this paper. The hydrodynamic coefficient CD and Cu related to KC number and the effect of direction of wave incidence are also given, which can be used in engineering practice.     

薛家岛湾沉积动力学特征及海港开发研究

于１９９０年秋对胶州湾内的薛家岛湾进行海洋水动力条件及积动力学特征,泥沙运动规律研究,为开发建设港口提供科学依据。结果表明,湾内深大于１ｍ的海底泥沙发生“全面移动”的时间,一年内仅有１－２ｄ,其余处于稳定状态或“表面移动”状态。湾内泥沙来源很少,预计建港后,港池和航道年平均回淤量分别小于１６ｃｍ,１０ｃｍ对于开发中小型港口十分有利。

黄河三角洲地貌环境体系

黄河三角洲是由三角洲上部冲积平原一下部冲积海积平原（超潮滩）─周边潮滩三个区带的地貌系列构成．它们之间形成三条地貌环境岸线，是一个复杂而统一的陆上─潮滩堆积地貌体系．该体系研究对三角洲发育．环境及其开发利用有一定理论和实践意义．     

水库鱼产力评价标准与模式的研究

本文在总结国内外已有成果的基础上,运用专家系统和灰色统计方法,初步建立了一套水库鱼产力评价的指标体系、指标权重体系和指标标准体系,首次给出了比较系统和具有普适意义的评价方案;并运用模糊数学方法建立了综合定量评价模式,从而在很大程度上解决了以往评价中由于多指标重迭、交错造成的难判、误判问题,为水库渔业资源的合理开发利用提供了比较科学的依据。     

Research on Characteristics of Density Current Under the Action of Waves

In this paper,the characteristics of density current under the action of waves are describedwith the help of flume experiment and theoretical analysis.The study shows that turbid water under the ac-tion of the waves can present three types of motion,i.e.significant stratification,fragile stratification andstrong mixing.The motion of turbid water presents significant stratification when(H/D)/△ρ/ρ~(1/2)≤4.5,generally this state is known as density current.The formulas of motionvelocity,thickness,and discharge of density current moving on horizontal bottom are derived by use of ba-sic equations such as momemtum equation,equation of energy conservation and continuity equation offluid.The time-average velocity and the thickness of density current under the action of waves have a rela-tionship with such parameters as relative density(△ρ/ρ),wave height(H),and water depth(D).Whenthese parameters are determined,the time-average thickness and motion velocity of density current are al-so determined.The relat     

海洋生物-光学算法研究──南黄海叶绿素浓度的估算

根据1995年9月中日合作南黄海现场观测资料，对南黄海生物一光学算法进行研究。首先对南黄海现场多光谱反射比数据进行因子分析，解反射比协方差矩阵的特征问题；解出特征值和对应的特征向量，求出主因子，然后建立叶绿素a浓度对主因子的多元线性回归方程，并对算法进行回报和预报检验。计算结果表明，该算法具有较高精度，同时也显示出天气条件对估算精度产生较大影响。     

Static Analysis of Collision Strength of Offshore Platform

In this paper a numerical analysis method combining FEM incemental technique with limit analysis concept is proposed for the study of the static strength of offshore platform in collision. Large deformation and plasticity are accounted for and the limit yield surface expressed by generalized stress for a tubular section is derived. The modified stiffness matrix of space beam element is formulated by Plastic Node Method. The buckling behavior of beam columns can also be taken into account. It can trace the generation of plastic hinges during loading and finally the ultimate strength of offshore platform against collision is obtained.
