中国沿海星虫动物门名录

取1980～1989年间在我国沿海进行星虫动物区系调查的标本和有关资料做了整理、鉴定,共39种,分隶于2纲,4目,6科,12属。其中1种在我国为首次记录。     

南极半岛西北部海域软体动物双壳类的研究

1984-1985年中国首次赴南大洋考查期间，在南极半岛西北海域(62°06.8′－64°24.′5S，56°2.8.′6-62°3l.′0W)进行了底栖生物调查，并在中国南极长城站附近进行了潮间带采集，共获得软体动物双壳类100余号近500个标本，经分类研究，共有13个科24种，其中7种为该调查海域首次记录，3种只鉴定到属。它们大多数是壳小，壳质极薄脆的环南极分布的南极种和亚南极种，明显地显示出寒带高纬度海域的区系特点。     

钛型吸附剂的表面特性

用自装的BET容量法装置测定了几种粒状钛型吸附剂的比表面及其孔径分布。测定是在常温减压下进行的。结果表明:钛型吸附剂在加铀海水中的吸铀量与样品的比表面及孔径分布有一定的内在联系。这种表面性质的研究对吸附剂的筛选有重要的指导意义。     

Distribution and number change of the Littorinid(Gastropoda) on intertidal hard bed in the Jiulong Estuary, Fujian Province

-Among four species of Littorinid, Littorina scabra, L. brevicula, Nodiliitorina millegrana and N. pyramidalis pyramidalis, on the hard intertidal zone in the Jiulong Estuary, Fujian, L. scabra has the most extensive distribution both vertically and horizontally, and the highest anual average density. The uppermost limit of vertical distribution of N. pyramidalis pyramidalis is higher than the other three Littorinid. Desiccation is a main factor affecting the uppermost limit of vertical distribution of the Littorinid. The increasing wave action will raise the uppermost limit vertical distribution of Littorinid. With seasonal changes, the densities of the Littorinid also change in different tidal zonations. Difference in salinity is the main factor affecting the horizontal distribution of the Littorinid in the estuary.     

The relationship between tidal current field and sediment transport in the Huanghai Sea and the Bohai Sea

-Based on a two-dimensional numerical M2 tidal model of the Huanghai and Bohai Seas, sediment transport of particles with different sizes in the computational area is given. It is concluded that tidal currents play an important role in sediment transport and deposition in the Huanghai and Bohai Seas.     

Occurrence and environmental implications of magnetic iron sulfides in stiff muds from the continental shelf of the East China Sea

Magnetic properties were measured on 370 vibrocores obtained from the outer continental shelf of the East China Sea, with the aim of reconstructing environmental changes during the late Quaternary. High SIRM/χ values (>25 kA m⁻¹) found in stiff muds of late Pleistocene age suggest the presence of magnetic iron sulfides, especially greigite. Framboidal aggregates of greigite were further identified by scanning electron microscopy (SEM) and attached energy dispersive X-ray (EDAX) analyses, as well as powder X-ray diffraction (XRD) analyses of the magnetic separates. The occurrence of magnetic iron sulfides indicates the complex oxidation–reduction of the stiff muds, resulting from exposure and inundation during the last glacial maximum (LGM) and the post-glacial transgression, respectively.     

印度洋东部金枪鱼延绳钓渔业研究--大眼金枪鱼(Thunnus obesus)的生物学特征

根据作者在印度洋东部海域的延绳钓生产实践,对渔获的大眼金枪鱼群体的群体构成、摄食、繁殖等基本生物学特征进行了初步探讨.结果表明,渔获群体由纯重10～115kg、叉长80～195cm个体组成,纯重与叉长关系式w=2.000×10-5×L2.969;渔获物以3～5龄个体为主,雄性个体所占比例明显高于雌性个体,且随年龄增长雄性个体所占比例逐步提高.鱼群在该海域产卵期较长,不同年龄组性腺发育节律有明显差异.     

几种养殖鲍同工酶生化遗传的比较研究

运用聚丙烯酰胺凝胶电泳对我国主要养殖鲍(皱纹盘鲍、盘鲍及九孔鲍)12种同工酶(LDH、ME、MDH、GPI、PGM、IDH、IDDH、SOD、EST、ODH、ADH、AAT)26个基因座位进行了分析．结果表明：EST、PGM可以作为区分三种(亚种)鲍的生化遗传标记；在所分析的位点中，未发现多态现象，表明三种养殖鲍杂合子缺失严重，其主要原因可能在于哑基因、近交与自然选择。     

珠江口悬浮颗粒物质的电泳性质

研究了溶液ｐＨ值、离子强度、氨基酸和微量金属元素对珠江口悬浮物电泳淌度的影响。结果表明：随着溶液ｐＨ值的升高，电泳淌度（负值）的绝对值开始逐渐增大，至ｐＨ值为８左右开始下降；随着离子强度的增大，电泳淌度的绝对值也相应增大，至１０－２时趋向平稳；氨基酸对电泳淌度无影响；而微量金属元素（Ｆｅ）对电泳淌度的影响取决于该元素的含量。     

广东三水盆地晚自垩世—始新世古地磁研究及构造意义

对广东三水盆地上白垩统三水组、大　山组、古新统莘庄组及始新统　心组、宝月组的系统的古地磁研究结果表明：（１）旋转运动是该区构造运动的主要形式，顺时针旋转盆地拉张发育，这时针旋转盆地挤压衰亡，发育的程度与旋转角度有关；（２）始新世该区旋转方向由顺时针旋转变为道时针旋转，对应于太平洋－库拉板块对欧亚板块作用方向的改变，说明三水盆地的形成发育与太平洋－库拉板块对欧亚板块的作用密切相关；（３）三水盆地所在的华南地块从晚白垩世至始新世在纬向上不存在明显的运动，一直停留在略低于现今纬度的位置上。
