热带气旋对黄、渤海影响的统计特征分析

本文统计分析了1949—2000年共52年影响黄、渤海的热带气旋时空分布特点及ENS0、西太平洋副热带高压与影响黄、渤海的热带气旋关系。结果表明，西太平洋热带气放以四种主要路径影响黄、渤海，其影响时间、频数及强度均有不同。ENSO和西太平洋副热带高压的强度、位置将影响热带气旋对黄、渤海影响的路径和频数。     

Current status of bacteriological parameters and DOC/POC in Xiamen coastal waters

The surface and bottom waters samples were collected from six locations in Xiamen western sea. The quantified estimation of bacterial production (3H-thymidine method) and observation of bacterial heterotrophic activity (14C-glucose method) have been made in order to have a better understanding of the role of marine bacteria and their activities. The results showed that the mean value of bacterial heterotrophic activity was 9×108 cells/(L.h) in the surface waters and 2.6×108 cells/(L.h) in the bottom waters. The mean value of bacterial production was 38×108 cells/(L.h) in the surface waters and 7.1×108 cells/(L.h) in the bottom waters. The relationship between bacterial production, heterotrophic activity, POC and DOC measured during this survey were discussed. The good understanding of the relationship between bacteria activity and total coliform was addressed.     

厦门港浮游植物对磷酸盐吸收速率的研究

用无载体32P同位素示踪测定海水中浮游植物和细菌吸收磷酸盐速率的方法，对厦门港浮游植物和细菌进行了研究。结果表明，厦门港海水中吸收磷酸盐的主体是浮游植物（几乎占100％），平均吸收速率为4．28×10－5μmol／（L·s），并且存在着晚秋＜冬＜初春的季节变化，培养实验的结果表明吸收速率的季节变化主要是由于种类更替和温度效应所致。     

苏、皖石炭系石灰岩的胶结作用

分析了苏、皖石炭系石灰岩的胶结作用。查明了胶结物的晶形、碳、氧同位素成分、发光特征及包体均一化温度。指出胶结作用主要发生在大气淡水补给较充分的含水层内,这与本区属海退成岩序列有关。     

南海表层流场的卫星跟踪浮标观测结果分析

运用卫星跟踪漂移浮标资料分析南海表层海流 ,研究了有关海域的表层海流特征。结果表明 ,秋、冬季入侵南海的黑潮水有一小部分沿台湾南岸折回黑潮主干 ,并有时在台湾西南外海形成反气旋涡旋 ,其余大部分黑潮水西行进入南海内部。吕宋岛西部沿岸流始于 1 3°N以南 ,沿菲律宾西海岸北上抵达吕宋岛西北角 ,与黑潮水混合后西行     

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。     

菲律宾海热含量分布及其变化的初步探讨

本文利用1986年及1987年秋季在菲律宾以东海域进行的CTD观测资料,分析了该海域上层海水热含量分布及变化,得出,热含量由南向北随纬度逐渐增大,这主要是北赤道流引起的等温线自南向北下倾造成的,另外也与南部和北部的冷涡和暖涡有关。本文认为,两年里热含量的差异可能与1986年生成的El Nin有关。另外,北太平洋赤道流体积输送量的变化与菲律宾海热含量的变化也有一定的联系。     

Numerical Study on Instantaneous Discharge of Unsorted Particle Cloud in Cross Flow

The mixing characteristics of particles such as dredged sediment of variable size discharged into cross flow are studied by a 3D numerical model, which is developed to model the particle-fluid two-phase flow. The Eulerian method with the modified k-ε parameterization of turbulence for the fluid phase is used to solve fluid phase, while a Lagrangian method for the solid phase (particles), both the processes are coupled through the momentum sources. In the model the wake turbulence induced by particles has been included as additional source term in the k-ε model; and the variable drift velocities of the particles are treated efficiently by the Lagrangian method in which the particles are tracked explicitly and the diffusion process is approximated by a random walk model. The hydrodynamic behavior of dumping a cloud of particles is governed by the total buoyancy of the cloud, the drag force on each particle and the velocity of cross-flow. The computed results show a roughly linear relationship between the displacement of the frontal position and the longitudinal width of the particle cloud. The particle size in the cloud and the velocity of cross flow dominate the flow behavior. The computed results are compared with the results of laboratory experiments and satisfactory agreement is obtained.     

高纯河豚毒素对蛙坐骨神经动作电位的影响

用电生理学方法观察了4种不同浓度的高纯河豚毒素(tetrodotoxin,TTX)对蛙离体坐骨神经动作电位的影响.实验结果表明:1μmol/dm3TTX在给药后7 min能显著抑制动作电位的上相幅度(P<0.05),但在给药后10 min才显著抑制动作电位的下相幅度(P<0.01);20μmol/dm3TTX在给药后3 min内能完全抑制动作电位的形成.1μmol/dm3TTX在给药后1~5min对动作电位传导速度的影响没有统计学意义,5μmol/dm3TTX在5min时可显著抑制传导速度(P<0.05),而10μmol/dm3TTX在2min时便显著抑制传导速度(P<0.05).实验结果提示高纯河豚毒素对蛙离体坐骨神经动作电位的影响存在剂量效应关系.
