大民屯凹陷地层水水文地质特征与油气聚集关系

对大民屯凹陷前第三系潜山、下第三系沙河街组地层水化学场研究发现，本区油田水总矿化度及二价阳离子浓度偏低，地层水总矿化度具有明显的垂向分带性，水体主要为陆相成因并受地表水渗入的影响较大，变质程度高，油田水的演化与盐类的溶解有关。该区地层水的流动受断裂和沉积砂体的控制，在水头压力、浮力动力场控制下其流动样式和分布规律反映了凹陷内油气的运聚规律，可为本区自生自储、新生古储式油气藏的判别提供有利证据。     

Sediment Transport in Rivers and Coastal Waters

Following Bagnold's approach, a relationship between sediment transport and energy dissipation is developed. The major assumption made in the study is that the near bed velocity plays a dominant role in the process of sediment transport. A general relationship between energy dissipation and sediment transport is first proposed. Then the equations for total sediment transport are derived by introducing the appropriate expression of energy dissipation rate under different conditions, such as open channel flows, combination of wave and current, as well as longshore sediment transport. Within the flows investigated, the derived relationships are fairly consistent with the available data over a wide range of conditions.

不同季节的企鹅珍珠贝游离珠植核效果比较

在雷州流沙港湛江海洋大学珍珠研究室实验基地分别于春、夏和秋季进行了企鹅珍珠贝游离珠植核实验。其中，春季插核的死亡率最低，为15.1％--16．2％，留核率最高，为10％左右：而夏季插核的死亡率最高，为63．56％，留核率也仅为2．22％：秋季插核的留核率最低，仅收珠1颗，留核率为0．35％，死亡率也较高，为54.4％。结果表明，春季是企鹅珍珠贝较适宜的插核季节。

Three-dimensional numerical simulation of obfique wave action on vertical walls

A three-dimensional numerical model based on the potential theory was developed to study the oblique wave action on vertical walls. A source term inside the domain was used to generate incident waves and outgoing waves were dissipated by sponge layers and transmitted by radiation boundaries. The finite difference method was used to solve the governing equations and boundary conditions in the regular transformed domain in σ-coordinate. Satisfactory agreements between the numerical predictions and experimental results of wave force were obtained. It is concluded that the maximum wave force acting on the vertical walls is induced by the obliquely incident waves rather than the normally incident waves.     

度量泥炭腐殖化度的一种简便方法:泥炭灰度

介绍了一种度量泥炭腐殖化程度简便易得的指标——灰度。通过将同一剖面灰度测量结果与传统的腐殖化度测量结果进行对比，发现二者的变化具有较强的相关性，说明导致二者变化的因素大致相同。泥炭赋色物质鉴定的实验表明腐殖质含量变化是引起灰度在剖面上变化的原因，从而进一步论证了用灰度值作为泥炭腐殖化程度指标的可行性。
