春季东海表层水叶绿素a含量分布特征

依据“科学一号”调查船１９９４年４月在东海１０个断面上所进行的表层水连续走航观测资料，研究东海表层水叶绿素α含量在不同空间尺度上的分布特征和变化规律。结果表明，叶绿素α含量在陆架区高，在外海低；测区南部海域的含量一般高于北部海域。叶绿素α含量的分布形态变化很大，在某些外海深水区，叶绿素α含量连续百科公里没有显著变化，变化幅度小于０．２ｍｇ‘ｍ＾３；而在某些近海浅水区，叶绿素α含量在不到１公里范围内

Experiments in numerical modelling of the Pacific sea surface temperature anomalies

By using the atmosphere-ocean coupled model (CGCM) which is composed of a 2-level global atmospheric general circulation model and a 4-layer Pacific oceanic general circulation model developed in the Institute of Atmospheric Physics of Chinese Academy of Sciences, and two model climatological fields got from the two independent models' numerical integrations respectively, the Pacific sea surface temperature anomalies (SSTA) from 1988 to 1989 are simulated in this paper with observed atmospheric general circulation data and sea surface temperature fields as initial conditions and monthly coupling scheme. In order to remove systematic biases of the model climatological fields, interaction variables between atmosphere and ocean are also corrected simultaneously. The experiments show that the simulation results can be improved effectively if these interaction variables are corrected in spite of the fact that there always exist systematic biases in independent numerical simulations of atmospheric part and oc     

鹧鸪菜组织和细胞培养的研究Ⅳ.藻体任意碎片的培养与损伤藻体再生的观察

把鹧鸪菜藻体切成大小不同的切段、以及任意切碎,培养于添加氮、磷素的消毒海水中,后者分10℃、15℃、20℃、25℃四种不同温度条件培养,结果全部切段、切碎片都很快再生出假根附着于基质,并再生出一至多个叶状体;叶状体长大后从基部长出新的假根成为完整的幼苗(再生苗)。试验表明,大的切段其再生苗生长快、长度大,但出苗率(一定长度的藻体长出再生苗数量)低。培养温度较高时(20—25℃),藻体任意切碎片再生速度快、附着速度快、数量多且较牢固。利用藻体切碎片来培养鹧鸪菜幼苗是可行的;培养的适宜温度为20℃以上、海水比重为1.010左右。本文还对鹧鸪菜损伤藻体再生的情况(繁殖生殖学)进行一些观察和描述。     

对虾养殖水质与饵料的关系研究

本文报道投喂不同厂家生产的对虾配合饵料致使水质因子变化的比较试验。结果表明：对虾养殖水体的ｐＨ、溶解氧及氨氮含量的变化和饵料的质量有直接关系，且影响到对虾的生存。而养殖水体的盐度、温度的变化和饵料的相关性不甚明显。文中还对配合饵料影响养殖水质因子变化的机理作了初步探讨。     

大连湾水域浮游桡足类的分布

本文根据１９８２年４月至１９８３年５月在大连湾周年生态调查中获得的资料，分析了大连湾浮游桡足类的数量分布和季节变化。结果表明，大连湾共有浮游桡足类２２种，其中优势种大网为中华哲水蚤Ｃａｌａｎｕｓｓｉｎｉｃｕｓ；中网为小拟哲水蚤Ｐａｒｕｃａｌａｎｕｓｐａｒｖｕｓ、拟长腹剑水蚤Ｏｉｔｈｏｎａｓｉｍｉｌｉｓ、短角长腹剑水蚤Ｏｉｔｈｏｎａｂｒｅｖｉｃｏｒｎｉｓ。桡足类总量年高峰，大、中同各有２次，最高峰分别为２月和８月。本文还讨论了几种环境因素对浮游桡足类分布的影响。     

舟山沿海单齿螺（Monodonta labio）种群的年龄结构,生物量与生长特征

本文报导了采自舟山沿海单齿螺种群的年龄结构、生物量与生长。自然种群的单齿螺年龄组成以１＾＋和２＾＋龄占优势，壳高、壳宽、壳口高、厣径、体重等生长参数的回归关系良好，单齿螺的生长完全可以用壳高来表示。单齿螺以第一、二年生长最快。采捕季节可定在四、五月间，采捕规格应在壳高１６ｍｍ以上。     

海带雌性原生质体的分离与培养

于1993年1月 - 1993年4月，为了制备遗传性纯一的基因工程受体，用酶法从海带雌配子体单性生殖系分离雌性单倍体原生质体。从皱纹盘鲍消化腺及消化器官提取出鲍酶，在25°C下、1％（W／V）的鲍酶与2％（W／V）的纤维素酶（Onozuka R－10）合用能有效解离单细胞和原生质体。海带雌性原生质体经2d培养再生了细胞壁。     

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.     

Fractal Dimension and Fractals in Ocean Engineering

- This paper discusses the application of fractal dimension and fractals in ocean engineering. To handle some ocean environment problems, the existing fractal method, in which the fractal dimension is a constant, can be used. For some complicated problems in ocean engineering, this paper presents the concept of the variable dimension fractals (D = f(r)), i. e., the fractal dimension D is the function of characteristic scale r instead of a constant. By using variable dimension fractals, several deformation and stress states of offshore structures are described.
