海平面

This paper probed into the sea-level changes from the latest Ordovician to the earliest Silurian and thesubdivision of the Ordovician-Silurian boundary based on the study of biostratigraphy, chemical stratigraphyand sequence stratigraphy.

本文通过生物地层、化学地层和层序地层的研究，对晚奥陶世晚期至志留纪初期的海平面变化以及奥陶／志留系界线的划分进行了探讨。

And furthermore basing on the marks of biostratigraphy and chronostratigraphy and relatively reliable isotopic age of the 14 3rd-order sequences associated with time-space match relation of biostratigraphy and sedimental system, the formed time limits of the 3rd-order sequences is calculated primarily as 1.5-3Ma, mainly appearing at 2Ma.

进而，结合生物地层及沉积体系的时空匹配关系等多方面的综合分析，对14次三级海平面升降事件的生物地层和年代地层的标识和参考已发表的同位素年龄数据，初步估算出三级层序的形成时限为1.5-3Ma，集中出现在2Ma。

They set off earthquakes,raised the seas,and sank the city faster than you can say blub,blub,blub.

他们制造地震，抬高海平面，在你说话的瞬间就把整个城市淹没。

According to this study, we can clearly see that the essential discrepancy of global averaged SLP lies over the continents in boreal summer.

可以清楚地看到模拟的全球平均海平面气压的主要误差是在陆地上。

The field investigation indicates that there are four phases of development of carbonate breccia wedge of LST, which reflects that this area experienced at least four times of significant sea level changes in the Early-Middle Triassic.

野外调查发现研究区共发育4期低水位期碳酸盐岩角砾岩楔，说明该区在早－中三叠世至少经历了4次明显的海平面变化。

By comparison, seas rose about 6 to 9 inches in the 20th century.

比较起来，在20世纪，海平面上升了大约6到9英寸。

Passing the calculation analysis of the characteristic index number, we discover that there is obvious annual variety regulation of it on the all sea region .

通过特征指数计算分析发现，各海域海平面异常特征指数存在较为明显的年际变化规律。

Rising sea levels and the melting of permafrost are causing their island to quickly erode into the Chukchi Sea.

海平面升高和融化的永久冻土是引起他们的岛屿迅速腐蚀到楚科奇海。

Within two days, activity became localized to a central vent and fire fountains constructed a cinder and spatter cone 350 feet (100 m) above sea level.

在二天之内，在海平面之上的地方活动成为了修建一个对中央出气孔喷火炭渣的350英尺(100 m)锥体。

In this research, the index for Hadley circulation intensity is defined as the maximum positive value of the zonal mean streamfunction occurring within the latitudinal zone of 0°~30°N, and index for NPO as normalized sea level pressure difference between the region (20°N, 180°~160°W) and the region (60°N, 180°~160°W).

本文选取0°~30°N区域里最大质量流函数来描述北半球Hadley环流强度随时间的演变，利用(20°N， 180°~160°W)和(60°N， 180°~160°W)区域平均的标准化海平面气压差代表NPO强度。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.
