降低水蚯蚓生产成本的若干措施

本文介绍我校高畦深沟种植蔬菜水稻沟中培育水蚯蚓的方法，利用该方法培育水蚯蚓不占用耕地，能节省场地租金。文中还介绍了节省饲料、劳动的若干方法。     

海岸沉积物中微量金属的早期成岩作用行为用作指示过去生成环境的变化

沉积物中有机质在氧化降解作用时，结合态金属Ni、Cu和Cd被释放入孔隙水中和返回水柱中．海岸沉积物的最上部沉积物层的孔隙水中，溶解的Cu．Ni和Cd通常比底层水富集．在较深的缺氧沉积物中，溶解的金属含量一般较低．     

关于胶莱盆地东南缘基性火山熔岩喷发时代上限的讨论

首次对采自青岛即墨WN部两个深钻孔中新鲜玄武岩样品进行Rb-Sr同位素测年,测定年龄值为65.77±13.6Ma。认为该年龄值代表了胶莱盆地东南缘基性火山熔岩喷发的时代上限,对于整个胶莱盆地中基性火山岩的划分和对比具重要的年代学意义。     

珠江河口西南风强迫下潮流场的数值模拟

采用Backhaus三维斜压模型模拟了均匀西南风场对珠江口近岸海域的影响，并与无风情况作了对比；通过对珠江河口盐度场及风生环流的分析比较，结果表明，模型较为真实地再现了夏季珠江河口的水动力学特性。     

Stuidies on the Technology for Mass Production of Abalone Breeding

Based on the traditional way of abalone breeding,the technological process of industrial abalone breeding suitable for the coastal areas of southern China has been developed.The process is simple and easy to handle,and results in a high yield of young abalones after being applied.     

浮体间距对多浮体系统水动力系数的影响

根据三维线性势流理论，采用格林函数法，对多浮体系统的水动力系数进行了数值分析。数值算例中给出了在固定波频下水动力系数与浮体间相对位置关系曲线。水动力系数的变化幅度随着浮体间距离增大而变小。随着浮体间距的变化，水动力系数极值的出现具有明显的规律，相邻的极大值(或极小值)的间距为半个波长或一个波长。     

牙鲆年龄和生长的研究

本文根据1980—1986年间连续逐月牙鲆生物学测定和耳石观察资料,确认其年轮形成期在3—5月,主要在4月。经标准von Bertalanffy生长方程拟合,鱼体体长(mm)年间生长规律为: ♀:L_t=800.10[1-e~(-0.2323(t-0.0254))] (?):L_t=690.62[1-e~(-0.2557(t+0.1211))]依体长与体重间相关关系计算渐近体重和最大生长速度,雌鱼分别为8370.43g和865g/a;雄鱼分别为4867.15g和554g/a。对低龄鱼(0—Ⅲ)生长特征模拟结果表明,雄鱼体长生长的季节变动幅度(C=1.07,k=0.5925)明显大于雌鱼;当年生雄鱼在7—9月的生长速度为年内最大。     

Elemental geochemical records of seafloor hydrothermal activities in the sediments from the Okinawa Trough

The major and minor element contents in the sediment core H9 from the hydrothermal fields of the Okinawa Trough show a sharp change at the depth of 80 cm. The elements enriched in the upper 80 cm core are those enriched in the hydrothermal deposits and in the surface sediments recovered from the hydrothermal fields in the trough, which indicates the input of hydrothermal materials. Comparing with other hydrothermal sediments from Mid-ocean Ridges or the Lau Basin, the degree of the enrichment of elements iron, copper,cobalt, and nickel is relatively low. However, the enrichment of elements manganese, lead, arsenic, antimony and mercury is remarkable. The average contents of these elements in the upper 80 cm core sediments are three to six times those in the lower section, and 3~12 times those in the surface sediments which are not influenced by hydrothermal activities. Hydrothermal activities have contributed significant manganese, lead, arsenic, antimony and mercury to the sediments, and these elements are distinct indicators for the hydrothermal activity in the Okinawa Trough. The significant enrichment of these elements in Core H9 upward from the depth 80 cm indicates the start or the significant enhancing of the hydrothermal activity in this area at about 5 740 aB.P. The average accumulation rate of manganese during this period is about 40 461 μg/(cm2·ka), which is similar to the hydrothermal sediments in the Lau Basin or the East Pacific Rise.     

黑潮水入侵南海的水文分析：Ⅱ.1994年8—9月期间的观测结果

利用１９９４年８－９月期间，由台湾海峡两岸的４艘海洋调查船在南海东北部海域所获之ＣＴＤ和ＡＤＣＰ资料，并结合１９９２年３月间在同一海域获取的ＣＴＤ资料及部分历史水文资料，对该区域的海水特性以及黑潮水入侵南海等问题进行了分析探讨。     

油田水动力系统与油气藏的形成

油田水中存在“沉积承压水”和“地表渗入水”两个相对独立而又相互作用的水动力系统,前者由上覆地层重量所引起的地静压力以及地静压力等引起的异常孔隙流体压力所形成,具有内循环承压式水交替特征,后者为大气降水和地表水向储集层的渗入而形成,以外循环渗入或水交替为特征。这两大系统（尤其是前者）的作用在很大程度上控制了含油气盆地中油气的运移、聚集和保存,油气聚集区主要位于水文地质带中的交管阻滞一停滞带内,沉积交替强度的低值区是油气富集区,沉积水的离心流使凹陷中的油气围绕凹陷中心呈带状分布。
