东海泥质和砂质沉积区悬乳物垂向分布的季节文化特征

9404，9410，9702及98074个航次东海泥质和砂质沉积区总悬浮颗粒物的季节调查显示由于冷涡区海水的底层幅聚作用使得位于冷涡中心的111站悬浮物含量高且集中在成层，111站海水中悬浮物含量冬，春季高，夏，秋，秋季低，而410站则是春，夏高，秋，冬低，东海悬浮物的垂向分布可归纳为4类：上低下高型，上高中低下高型，上低中高下低型及均匀型。

中国对虾(Penaeus chinensis)消化系统发生的研究

本文对中国对虾消化道和中肠腺的发生进行了研究。完整的中肠管形成于Ｎ３期，它是由幼虫腹面的内胚层板向背中线上卷合拢而形成。在Ｚ１期消化道完全贯通。至Ｍ１期，胃分化为贲门胃和幽门胃两部分，中肠前盲囊和中肠后盲囊也在此期出现，同时胃磨的雏形发生，但完整的胃磨形成于Ｐ期。另外，中肠腺始于Ｎ４－５期中肠前端突出的两对中肠腺盲囊。第一对中肠腺盲囊于Ｍ３期退化消失，而第二对中肠腺盲囊则发育为成体的中肠腺。中肠腺小管由４种不同类型的细胞（胚性细胞、吸收细胞、纤维细胞和泡状细胞）所组成     

考虑底摩擦的波浪折射计算

本文用考虑底摩擦的折射模式计算了浅水中波高和波向分布。作为一个例子,根据不同的摩擦系数和不同的边界条件计算了一种简单海底地形的折射系数、衰减系数和折射角,所得结果与不考虑底摩擦的折射模式结果进行比较,发展它们之间存在一些差异,表明在浅水中底摩擦对波高有一定影响。     

A Note on Soil Structure Resistance of Natural Marine Deposits

It has been well documented that natural normally-consolidated marine soils are generally subjected to the effects of soil structure. The interpretation of the resistance of soil structure is an important issue in the theory study and engineering practice of ocean engineering and geotechnical engineering. It is traditionally considered that the resistance of soil structure gradually disappears with increasing stress level when the applied stress is beyond the consolidation yield stress. In this study, however, it is found that this traditional interpretation of the resistance of soil structure can not explain the strength behavior of natural marine deposits with a normally-consolidated stress history A new interpretation of the resistance of soil structure is proposed based on the strength behavior. In the preyield state, the undrained strength of natural marine deposits is composed of two components: one developed by the applied stress and the other developed by the resistance of soil structure. When the applied stress is beyond the consolidation yield stress, the strength behavior is independent of the resistance of soil structure.

潮汐对瞬态气候响应模拟的影响研究

In this study, the impact of oceanic processes on the sensitivity of transient climate change is investigated using two sets of coupled experiments with and without tidal forcing, which are termed Exp_Tide and Exp_Control,respectively. After introducing tidal forcing, the transient climate response(TCR) decreases from 2.32 K to 1.90 K,and the surface air temperature warming at high latitudes decreases by 29%. Large ocean heat uptake efficiency and heat storage can explain the low TCR in Exp_Tide. Approximately 21% more heat is stored in the ocean in Exp_Tide(1.10×10~(24) J) than in Exp_Control(0.91×10~(24) J). Most of the large ocean warming occurs in the upper 1 000 m between 60°S and 60°N, primarily in the Atlantic and Southern Oceans. This ocean warming is closely related to the Atlantic Meridional Overturning Circulation(AMOC). The initial transport at mid-and high latitudes and the decline in the AMOC observed in Exp_Tide are both larger than those observed in Exp_Control. The spatial structures of AMOC are also different with and without tidal forcing in present experiments. The AMOC in Exp_Tide has a large northward extension. We also investigated the relationship between AMOC and TCR suggested by previous studies using the present experiments.
