简介：Dongpu下垂位于Bohai海湾盆的南方，中国，并且有丰富的油和煤气的储备。迄今为止，没有它的地热的地的系统的文档。这研究测量了岩石从47口井的324个核心的热电导率，和计算岩石为不同形成的热电导率。地热的坡度和陆上的热流动从523口井在892形成严峻数据的基础上为192口井被计算。结果证明Dongpu下垂由在稳定、活跃的构造区域之间的一块中等温度的地热的地被描绘，与32.0°C/km的一个平均地热的坡度和65.6mW/m2的陆上的热流动。在Dongpu的地热的领域下垂被Changyuan，黄河，和Lanliao地下室差错显著地控制。他们在Paleogene发展了，Dongying运动发生在Dongying形成depositional时期。地热的地分发有一个类似的特征到Dongpu的构造框架下垂，也就是二subsags，一个高举，一个陡峭的斜坡和一个轻轻的斜坡。油和煤气的分发仔细与现在的地热的领域被联系。工作可以为重建提供限制在Dongpu的热历史和当模特儿的来源岩石成熟进化下垂。

简介：一三维(3-D)有限体积沿海的海洋模型(FVCOM)在Benoa海湾被用于水循环和海水交换的学习，巴里岛。M2潮汐的部件在开的边界被强迫，来自六条河的分泌物在数字计算被包括。FVCOM生产的M2潮汐的举起与观察数据有一个好协议。M2潮汐的水流成功地也在ebb潮和洪水潮条件下面被计算。非线性的M2潮汐的剩余水流被海岸线几何学生产，特别包围在Serangan岛和Benoa半岛之间的狭窄的海峡。潮汐的剩余水流也在海湾嘴在海湾和一个小旋涡以内产生了二个小旋涡。河分泌物影响的咸度分发能成功地被计算，在数字计算和观察结果有好关联的地方(r2)0.75。最后在Benoa海湾交换以便检验海水，追踪住处时间的方法和计算的Lagrangian粒子被使用。到涌出海水的粒子运输的机制被两个方法清楚地描绘。

简介：在2011年10月，种形成，分发，和潜在的生态的风险在厦门海湾基于表面沉积的调查对在这个区域的重金属(Cu，Pb，Zn，Cd，和Cr)的评价用顺序的抽取方法和生态的风险评价被学习方法。结果显示了：(1)这些重金属的全部的集中被流量，工业废水，和污水影响，并且都比的在沿海的区域是更高的近海区域当Pb的最高的区域由于空气是远一些的离开沿海的水时免职；(2)顺序的抽取建议Cu主要与剩余被填写，Fe/Mn-oxide绑了部分，Pb被绑在Fe/Mn-oxide，Zn和Cr被剩余统治，并且Cd跳了到可交换并且碳酸盐部分；(3)移植和转变顺序的顺序是Cd>Pb>Cu>Zn>Cr和污染的度是Cd>Pb>Cu>Zn>Cr；并且(4)第二等、主要的阶段的比率证明Zn和Cr两个都是干净的，Cu可以被弄脏，Pb中等被弄脏，当Cd重重地被弄脏时。

简介：Tanlu差错(Liaozhong片断)沿着NNE方向和它通过Liaodong海湾径直去被划分成三个片断，即，北片断，中间的片断和南部的片断，根据在结构的特征的差别。在存款厚度有明显的变化，下垂结构，构造性质和层的另外的方面。Tanlu差错是有关在Liaozhong的水库形成的一个特殊控制因素下垂。首先，它的活动影响paleogeomorphology和paleogeographic框架并且控制沉积外形的分发然后他们继续控制来源岩石和水库沙身体的分发。第二，它的活动影响结构的形成和变丑，控制丰富的陷井的形成并且引起一些陷井的破坏。第三，它的活动也在差错，沙身体和不顺从表面之中影响并排关系并且作为主要的烃translocation系统控制三的函数和功效。在JZ21-1，JX1-1和LD27-2油和气体的烃水库形成过程回答的这份报纸，Tanlu罢工的代表滑倒差错地区主要被分析。烃水库形成的模式能作为滋养作为土壤和油和气体作为followshydrocarbon来源行为被概括；烃逐出依靠根；烃移植依靠箱子；水库在早午餐形成，整个过程跟随烃在罢工积累的模式滑倒，油和煤气的水库象树的生长一样形成。
