潮汐沉积率与沉积间断

在浙北奥陶系文昌组和长江三角洲开敞型淤泥质海岸非潮道潮汐纹层研究的基础上,得出与国外同类研究相近的沉积率。现代海岸进积速度和潮坪沉积的观察及测试证明,上述沉积率是难以置信的。现代潮坪观测表明,潮汐纹层在形成过程中即包含着改造,所保留的纹层占应形成数的不到１０％,其余９０％以上被侵蚀。小型层序是风暴和平静天气的产物,为风暴层序,与大小潮周期无关。其地层中保留的数量不到应生成数的１０％,其余９０％被改造。小型层序被侵蚀,其中的纹层随之消失。致使潮坪层序中保存的纹层数仅为应形成数的０．２％。被改造的纹层和单层留下的仅是侵蚀面,即小间断。在进行潮汐沉积高分辨率的研究时应充分重视沉积间断的作用     

海洋复杂体系氧化还原状态的描述与确定及独立电对概念的提出

木文提出海水氧化还原体系状态的性质取决于其主要独立电对的氧化还原性质。并测定了某些海洋沉积物样品的Eh、pH、酸挥发性硫及其间隙水中氨等参数,以所得数据为例进行讨论、归纳和推理,得到了一些经验性的结论。图5,表3,参考文献13。     

Application of Microbial BOD Sensors in Marine Monitoring

A strain of yeast, which can endure high osmotic pressure, is employed for the sensitive material of the microbial BOD sensor. Two immobilization methods are used, I.e. Calcium alginate gel be ads and PV A gel beads. The results show that the PVA gel beads is better. The influences of osmosis and heavy metal ions on the yeast entrapped in the PVA gel beads are also studied in the experiment.     

山东沂沭断裂带成生时代探讨

郯庐断裂带的成生时代基本上有两种观点：巨大平移说，认为它形成于中生代。而垂直运动说，则认为它形成于太古代。     

福州应建成多功能的经济中心城市——对福州城市发展战略问题初探

最近一个时期,福州乃至全国众多专家、学者,十分关心福州经济发展问题,人们谈起福州,总离不开“山海侨特”、“腹地广阔”、“科技教育发达”等,但如何发挥这些优势,它的战略地位、薄弱环节表现在哪里?今后战略方针、战略目标是什么?应该采取哪些战略措施等,这是很值得我们深入研究和认真探讨的。     

上海海平而变化规律及其长期预测方法的初探

根据１９１２￣１９９３年吴淞验潮站年平均潮位资料，采用多变量逐步回归和最大熵谱分析等方法分析以吴淞为代表的上海绝对海平面长期趋势的周期变化规律，并依此规律建立用作绝对海平面长期预报的叠加模型，由此预测２０１０年和２０３０的上海色对海平面相对于１９９０年的上升值为５ｃｍ，１１ｃｍ，结合已分布的未来上海地区地面和速率预测值，给出上述时段上海相对平面上升预测值分别为１７ｃｍ，３０ｃｍ。

Chemical Fluxes of Asian Rivers into Oceans and their Controlling Factors

Chemical fluxes of Asian rivers into oceans bear different regional variations. Three zones are characteristic of distinct dissolved sediment loads and yields and ionic concentration.Rivers into oceans in China play an important role in Asia because of their different chemical fluxes, among which those draining the Loess Plateau have high ionic concentration, low water discharges and dissolved sediment loads and yields.Climate, vegetation, soil and strata lithology, chemical weathering intensity and tectonic activity dominate chemical fluxes of Asian rivers into oceans, and different factors have different effects on the chemical fluxes of separate regional rivers. Rising of the Tibet Plateau also exerts an important influence on chemical compositions of rivers originating from it.
