Conditions for maintenance of reticulate dune morphology under modern flow environment include enough space for the development of secondary ridges on the primary ridges in order that the overall pattern can not be modified by the subdominant winds, and sufficient amount of sand supply for the secondary ridges that can withstand the dominant winds.

在背风坡，因原始气流方向、强度和沙丘背风坡形态等的不同出现弱的反向气流，相对强的附体未偏向流和附体偏向流等三种特征次生气流，它们控制着背风坡表面过程、沙丘移动性质、内部层理类型和产状。

Oil were recently discovered in brecciated limestone, micrite kimestone and dolomitized limestone associated with Jinding lead-zinc deposits.

兰坪坳陷的油气主要见於金顶矿区的下含矿层，储层主要为上三叠统三合洞组的灰岩和角砾状灰岩石。

In the drawings, Rasheed Street appears as a glistening pedestrian mall, with palm trees and restored porticoes above the two-story, columned shops.

在电脑模拟图中，拉希德街看起来是光彩耀眼的徒步购物中心，两层楼高的圆柱状商店上方有棕榈树和修复的廊柱。

Based on the high-resolution analysis of planktonic foraminiferal isotope and organic carbon of 91 sediment samples from two box cores located respectively in the southern and northern slopes of the South China Sea, the changes of sea surface temperature and paleoproductiviy of the past 2400 years were reconstructed. The sea surface temperature and the depth of thermocline varied in different stages during the late Holocene, with some short-term climate events such as the Little Ice Age.

对南海南、北陆坡两个箱式柱状样中91个沉积物样品进行了高分辨率的稳定同位素和有机碳分析，获得最近2400年以来上部海水温度和表层古生产力的记录，发现晚全新世南海的表层海水温度和温跃层呈现阶段性变化，且有小冰期等短期气候事件。

The horizontal dispersion of suspended particles in the intermediate nepheloid layer at the shelf margin is the major materials transport mode from shelf to the deep sea in the shelf margin.

陆架边缘的雾状层的水平扩散是陆架颗粒物质向深海输送的重要方式。

At the same time, the distribution mode of the strand shallow lake and the delta deposition system have been established in this region. The research on type and distribution regulation of subtle trap combining with geologic strata structure indicates that the south slope belt, ditch valley belt, Guangbei slope break and southwest of noselike conformation belt are the more advantageous belt to find subtle trap.

在层序地层格架内，通过古地貌研究和沉积体系研究，识别出低位沟谷带和坡折带等控制沉积的两种地貌，建立了本区滨浅湖沉积体系和三角洲沉积体系的分布模式，结合地层结构特点，对隐蔽圈闭类型及分布规律进行研究，指出南部斜坡带、沟谷带、广北坡折带及鼻状构造带西南端是寻找隐蔽圈闭的有利区带。

The structure was investigated by XRD and TEM, combining with the calculated metastable phase diagram. The results show that it is possible to obtain coupled structure in Zn-2%Cu peritectic alloy by rapidly unidirectional solidification method.

利用X射线衍射仪及透射电镜对层片状组织进行了相组成的分析，并结合计算亚稳相图对该组织的相及组织形成规律进行了分析，结果表明在快速凝固条件下Zn-2%Cu包晶合金中实现共生生长是可能的。
