现场海域水平扩散系数的探讨 Ⅱ．黄河三角洲埕北海域的计算

根据Ｔａｙｌｏｒ的湍流扩散理论和Ｈａｙ、Ｐａｓｑｕｉｌｌ提出的拉格朗日流和欧拉流的相关函数的相似性，用黄河三角洲埕北海域的实测资料，按四种不同方案计算出该海域的水平扩散系数和谱密度分布。指出：该海区潮流扩散系数主要受潮流的影响，其分布特征与潮流的分布基本一致，所求的水平扩散系数主要是由周期性的潮运动给予潮流扰动所致。方案４是通过富氏变换滤波消去了周期性潮流扰动，本方案计算的水平扩散系数是由周期为６ｈ以下的小尺度涡提供能量。     

中国对虾人工诱导雌核发育的研究 Ⅱ.紫外线辐射对精子顶体反应和受精能力的影响

研究了 36 5 nm波长紫外线辐射中国对虾精子对其顶体反应和受精能力的影响。结果表明 ,低剂量紫外线辐射促进精子发生顶体反应 ,大剂量辐射使精子丧失发生顶体反应的生理机能并死亡。 36 5 nm波长紫外线能够透过精荚和纳精囊盖 ,对其内精子起到杀伤作用。精液稀释液在紫外线下辐射 5～ 8s,仍有部分精子具有受精能力 ,但胚胎在早期阶段即死亡。人工诱导雌核发育的过程中 ,紫外线辐射精液稀释液 5～ 8s,可获得遗传物质失活的精子 (激活源 )。经透射电镜观察分析 ,紫外线对精子遗传物质的损伤是一种使染色质变性的化学作用。     

虾蟹海产品香味的前体物质的加热变化

本文研究了虾蟹海产品香味的前体物质在加热前后的变化。实验结果表明：对虾和蟹肌肉中的糖原和不饱和脂肪酸在加热前后含量下降，糖原是Ｍａｉｌｌａｒｄ反应的基础物质．不饱和脂肪酸是虾蟹肌肉香味中羰基化合物的前体物质。虾蟹肌肉中主要积累的核苷酸成分ＡＭＰ在加热后减少，而肌肉提取物中的游离氨基酸和结合氨基酸，特别是疏水氨基酸含量均增加。

环胶州湾公路海上段汽车尾气的环境影响

对类比路段进行连续模拟试验,进行现场调查,给出汽车尾气主要污染物的排污强度,预测了汽车尾气中CO、C_nH_m和NO_x的扩散范围。     

热带气旋活动对中国夏季雨带类型与ENSO的响应关系

本文分析研究了热带气旋１）活动与中国夏季２）３组（包括８种）主要多雨带类型的响应关系。同时对热带气旋活动与夏季大陆气温和ＥＮＳＯ事件的始终时间的响应关系，也进行了探讨。分析表明，夏季中国的雨带分布特征对热带气旋活动有着十分重要的指示意义。热带气旋活动与中国大陆气温有着正相关关系，与ＥＮＳＯ事件的发生有着反相关关系     

南黄海自生黄铁矿成因及其环境指示意义

样品为１９８９年采自南黄海，利用显微镜，电子显微镜，电子探针和化学分析方法，对自生黄铁矿的形态，成份和同位素特征进行研究，在此基础上就其成因与形成环境的关系进行初步探讨。研究结果表明，自生黄铁矿集合体形态可以分为聚莓，单莓和细粒３种，霉体特征的形态是早期成岩作用阶段沉积物随机堆积的结果，可以作了沉积成因黄铁矿的形态标型黄铁矿微量成份特征显示其沉积成因，同时亦表现对泥质沉积物地球化学背景值的继承性，     

Refraction-Diffraction Mathematical Model for Waves With Lateral Energy Transmission Mechanism and Its Verification

To solve problems concerning wave elements and wave propagation, an effective way is the wave energy balance equation, which is widely applied in oceanography and ocean dynamics for its simple computation. The present papaer advances wave energy balance equations considering lateral energy transmission and energy loss as the governing equation for the study of wave refraction-diffraction. For the mathematical model, numerical simulation is made by means of difference method, and the result is verified with two examples.     

一个具有下垫面温度耦合的大气环流的统计—动力模式

本文从动力学定律出发,推导了一个线性的、具有下垫面温度耦合的大气环流的统计—动力模式,并用该模式对500hPa高度场及1000hPa温度场作1～30天的平均预报试验。模式的预报结果大大优于惯性预报,但耦合与不耦合的结果差别不大。     

North Pacific Synthesis of the Joint Global Ocean Flux Study: Overview

This special issue is comprised of 13 papers, including this overview, and focuses on the synthesis of the Joint Global Ocean Flux Study (JGOFS) in the North Pacific which took place from 1997 through 2003. The effort was led by the JGOFS North Pacific Synthesis Group, with the aim of quantifying CO₂ drawdown by physical and biological pumps in the North Pacific by identifying and studying the regional, seasonal to inter-annual variations in the key processes, and understanding their regulating mechanisms. Emphasis was placed on the similarities and differences of the biogeochemical regimes in the eastern and western subarctic Pacific. Effort was also made to address the future research directions which arose from the scientific findings during the North Pacific JGOFS process study. A brief overview of the papers from view points of CO₂ drawdown by physical and biological pumps, spatial variability, and temporal variability from seasonal to decadal scales is made, followed by suggestions for the directions of future research. This revised version was published online in July 2006 with corrections to the Cover Date.
