太平洋海域海平面变化的灰色系统分析

应用灰色系统理论，对太平洋海域４８个长期验潮站的月均海平面分别建立了ＧＭ（１，１）模型。ＧＭ（１，１）模型能较好地反映太平洋海域的海平面变化的趋势，它除了能给出连续的海平面变化速率外，同时能方便地给出海平面变化的加速率。模拟结果表明，在太平洋地壳均衡假设下，太平洋海域的月均海平面以平均速率０．１７ｃｍ／ａ上升。在太平洋海域所取的４８个长期验潮站中，有４０个站在加速上升，全部站的平均加速度为０．０００２９ｃｍ／ａ２。且加速率逐渐增大。当然这些加速率都很小，但作为一种普遍性的趋势，这已足以说明：太平洋海域的海平面在加速上升

柴达木盆地昆特依盐湖的地球化学演化与古气候变化

１９９０年用铀系年代学及古地磁对昆特依盐湖沉积物进行年代测定，探讨该湖区地球化学演化与古气候变化关系。结果表明，该区最老的盐层形成于早更新世晚期（大于７３０ｋａ），大量的盐类沉积则始于３００ｋａ左右；盐湖沉积物中元素含量变化主要受古盐度、矿物、类质同象和吸附控制；沉积物水溶Ｆ／Ｃｌ比值与古盐度成反比关系；该湖２０００ｋａ以来的古环境演变：盐层形成于干冷、偏酸性的氧化环境，泥岩层形成于湿暖、偏碱性的     

牡蛎循环系统的研究

于１９８９－１９９０年在海南岛、广东蛇口以及青岛近海采集１２种牡蛎,进行循环系统的比较解剖学研究。首次提高了牡蛎的循环系统有两种类型,即附心脏型和无附心脏型。两者之间的主要区别是：（１）附心脏型无肌套血管,其外套血液主要来自环外套动脉和附心脏;无附心脏型,由于无附心脏和环外套动脉,其外套血液主要来自肌套血管。（２）附心脏型是通过出鳃静脉和外套静脉分别将鳃前部和后部的血液送回心耳;无附心脏型的外套静     

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。     

Studies on ultrastructure of oocyte in process of maturing in pen shell

The present paper deals with the ultrastructural changes of oocyte in the process of maturing in pen shell Atrinapectinata Linne. When it develops from the antecedent growth period to the accelerating growth period the annulate lamellae emerge, the RER better develop, the yolk granules with single and double layer membrane and are visible. In the well-developed mitochondria there is yolk stored. The Golgi vacuoles are brewing yolk granules. At the mature period the annulate lamellae and the Golgi bodies disappear, and there are only a few RER and mitochondria with poor cristae in the cytoplasm. All these might be well used for judging the maturity of the ootids in the process of the artificial propagation.     

摄食水平和性别对稀有鮈鲫生长和能量收支的影响

于1995年10月采集本所自繁有ju鲫（约1.03g/ind)，在30℃水温下进行摄食－生长实验，研究了从饥饿到饱食5个摄食水平对不同性别稀有ju鲫的生长和能量收支的影响，结果表明，鱼体干物和能量含量不受摄食率和性别的影响，随着摄食率的增加，雌鱼的湿重，干重和能量特定生长率均呈双对数增加，雄鱼湿重特定生长率呈双对数增加，而干物质和能量特定生长率呈指增加，雄鱼生长速度及摄食率低于雌鱼，随着摄食率的增加，食物能损失于粪便中的比例均呈上升趋势，损失于排泄物中的比例变化不大，呈下降趋势，用于代谢的比例呈下降趋势，用于生长的比例呈上升趋势，除饥饿组外，在各个摄食水平，雌鱼食物能用于代谢的比例较雄鱼低，而用于生长的比例较雄鱼高。     

Mechanisms controlling the temporal variation of the sea ice edge in the Southern Ocean

This paper examines the mechanism controlling the short time-scale variation of sea ice cover over the Southern Ocean. Sea ice concentration and ice velocity datasets derived from images of the Defense Meteorological Satellite Program (DMSP) Special Sensor Microwave Imager (SSM/I) are employed to reveal this mechanism. The contribution of both dynamic and thermodynamic processes to the change in ice edge location is examined by comparing the meridional velocity of ice edge displacement and sea ice drift. In the winter expansion phase, the thermodynamic process of new ice production off the ice edge plays an important role in daily advances of ice cover, whereas daily retreats are mostly due to southward ice drift. On the other hand, both advance and retreat of ice edges in the spring contraction phase are mostly caused by the dynamic process of the ice drift. Based on the above mechanism and the linear relation between the degree of ice production at the ice edge and northward wind speed, the seasonal advance of ice cover can be roughly reproduced using the meridional velocity of ice drift at the ice edge.     

The Levant Slumps and the Phoenician Structures: collapse features along the continental margin of the southeastern Mediterranean Sea

Two distinct series of slumps deform the upper part of the sedimentary sequence along the continental margin of the Levant. One series is found along the base of the continental slope, where it overlies the disrupted eastern edge of the Messinian evaporites. The second series of slumps transects the continental margin from the shelf break to the Levant Basin. It seemed that the two series were triggered by two unrelated, though contemporaneous, processes. The shore-parallel slumps were initiated by basinwards flow of the Messinian salt, that carried along the overlying Plio-Quaternary sediments. Seawater that percolated along the detachment faults dissolved the underlying salt to form distinctly disrupted structures. The slope-normal slumps are located on top of large canyons that cut into the pre-Messinian sedimentary rocks. A layer of salt is found in the canyons, and the Plio-Quaternary sediments were deposited on that layer. The slumps are bounded by large, NW-trending faults where post-Messinian faulted offset was measured. We presume that the flow of the salt in the canyons also drives the slope-normal slumps. Thus thin-skinned halokynetic processes generated the composite post-Tortonian structural patterns of the Levant margin. The Phoenician Structures are a prime example of the collapse of a distal continental margin due to the dissolution of a massive salt layer.
