Based on these, we will measure isotopic composition of boron in biological fossils, such as shell, foraminifer et al. producing from Ynaghu Village, Yanqing Basin, Beijing at early Quaternary and from the sediment of salt lake in Tibetan at Quaternary, and then offer a reliable boron isotopic evidence for determining their source and survival surroundings.

在此基础上对北京延庆杨户庄第四纪早期地层和青藏高原第四纪盐湖沉积产出的有孔虫、贝壳类等生物化石的硼同位素组成进行测定，为确定它们的海陆相来源及其生存环境提供硼同位素证据。

Planktonic foraminifera assemblages of 79 core top samples from the western and southern areas of the Indonesian Archipelago were grouped using cluster analysis. The results indicate that foraminifer assemblages make it possible to sub-divide the studied area in five provinces. The modern ocean characters and the surface sediment features from the five provinces are studied in the project.

本项目依据印度尼西亚多岛海及邻区七十九个海底表层样品的浮游有孔虫组合聚类分析结果，将该区划分为五个洋流活动区，对各区现代海洋学性质与海底表层沉积物特点进行对比研究。

Carbonates also occupy an important component, with E271 from 5.9% to 27.57% and E272 from 6.67% to 38.20%. A few foraminifer fossils were found in the sediment cores. These sediments are rich in Cu, Pb and Zn which are fallout from hydrothermal plume with iron oxides.

热液桩的沉积作用，使Cu、Pb和Zn在沉积物中富集，Cu/Fe、Pb/Fe和Zn/Fe比值低于热液喷口处的颗杜物中值，Pb表现出在海水中运移距离较短或者只有少量Pb随热液柱扩散运移。

Data include foraminifera counts and sea surface temperature estimates derived from marine sediment cores from the north Atlantic Ocean.

数据来自于北大西洋海底沉积物的钻芯，包括有孔虫类计算和海面温度估计。

Foraminifera grow in the ocean and when they die, mix with coral to become the sediment that forms atolls.

这种星沙可以在日本南部海域的珊瑚礁附近找到，常被旅游观光者采集到瓶子里当做幸运之物。

Lastly, a number of particle movement trajectories are simulated by Monte Carlo method, and the sediment concentration, siltation distribution in pumping station forebay are obtained.

蒙特卡罗方法的模拟结果十分形象直观。

The bad flow pattern will make the efficiency of the pump unit drop. Meanwhile, because there are a lot of sediments in sewage in the forebay , the bad flow pattern will make sediments depositing freely and the sediment deposition will cause worse flow pattern.

同时，由于排污泵站进水水流中含有大量的悬浮固体颗粒，不良的前池流态会使泥沙更容易在前池淤积，而泥沙淤积又进一步加剧了前池流态的恶化。

Experiment data of HCB desorption were simulated better by fast2slow two stage first2order kinetics model and dynamic parameters of HCB desorption were also calculated. Frap and Fslow , the fractions of contaminant present in the rapidly and slowly desorbing sediment compartment , were respectively 3716 % and 6214 %; krap and kslow , the rate constants of rapid and slow desorption , were 01066 9h - 1 and 01000 5h - 1 , respectively.

快、慢2 段一级动力学模型较好地拟合了六氯苯释放的实验数据，并得出了释放动力学参数：快速和慢速释放部分所占的质量分率Frap ， Fslow分别为3716 %和6214 %；快速和慢速释放速率常数krap ， kslow分别为01066 9h - 1和
