查询词典 sea level

However, such tidal overheight is often ignored in the current regional numerical simulation due to intensive computational requirement. Only the mean sea level is used as the fixed seaward boundary, which may wrongly predict the groundwater table position. Therefore, we aim to determine an equivalent seaward boundary through numerical modeling. The equivalent seaward boundary takes into account the tide-induced overheight effects.

然而，由于潮汐动边界处理的复杂性而导致巨大的计算量，在现有的区域地下水数学模型中，潮汐引起的海平面波动通常被忽略，仅仅以平均海平面高度作为模型的海岸边界条件，其预测出的地下水水位位置与实际情况可能会有一定的误差。

The X-35C touched down at Patuxent River NAS on 10 February 2001, completing the first-ever transcontinental flight of a JSF demonstrator aircraft and initiating a series of flight tests that demonstrated carrier suitability in sea-level conditions. The X-35C's flight-test program included a series of Field Carrier Landing Practice tests to evaluate the aircraft's handling qualities and performance during carrier approaches and landings at an airfield, and also included up-and-away handling-quality tests and engine transients at varying speeds and altitudes

With the rich sediments supplied by the Pearl River, under the paleogeography sedimentary background of Baiyun Sag continuously subsiding, with sedimentary sequences related to relative transgressive sea level change ,contrary to regressive eustasy, the Pearl River Deepwater Fan System has specific evolution characteristics, which left the sedimentary record controlled by peripherical significant geological events.

珠江深水扇系统以珠江为沉积物源、以持续深沉降的白云凹陷为沉积古地理背景、以与全球海退型海平面相反的相对海侵型海平面变化的沉积层序构成了其发育演化的特殊性，并留下了控制沉积的周边重要事件的记录。23.8 Ma等界面沉积速率和岩石地球化学特征均有突变，反映出物源区的变化，可能折射出与青藏高原隆升、南海扩张有关的重要事件，使得古珠江骤然向西部高原拓展，甚至较今天的珠江流域范围还广阔；承载珠江深水扇系统的白云凹陷持续沉降形成了陆坡内盆地，导致21~10.5 Ma BP多个层序深水扇垂向叠置充填的特殊沉积建造；根据60多口井资料建立的相对海平面变化曲线，具有与全球海平面变化相一致的三级旋回和不一致的二级旋回。

Through testing 45 carbonate samples collected from PermoCarboniferous caol measures of the Hedong coalfield,the distributions characteristics of carbon and oxygen isotopes in sequences are analyzed,whose feasibilities for sequence subdivision and correlation,as well as for study of relative sea level variations and late Paleozoic facies are also discussed.

系统分析了河东煤田上石炭统（C2）—下二叠统下部（P11）45个碳酸盐岩样品的碳氧同位素在层序中的分布特征，探讨了碳氧同位素应用于层序划分及对比、相对海平面变化研究及晚古生代地层沉积相研究的可能性。

At this stage sea-level westerlies are strong and zonal in character and they lie poleward of their normal position.

在这一阶段海平面上西风气流很强且属纬向性的，它较正常位置偏向极地(北半球上偏北或南半球偏南)。

English: 103. At this stage sea-level westerlies are strong and zonal in character and they lie poleward of their normal position.

在这一阶段海平面上西风气流很强且属纬向性的，它较正常位置偏向极地（北半球上偏北或南半球偏南）。

The time of the pedogenic process was in the last ice age, therefore this area was colder and drier in climate and lower in sea level than today. The main chemical process in the soil was oxidation, a period of the formation of oxide minerals such as limonite. With the deposition and covering of the marine facies layer in the postglacial period, the soil turned into diagenetic process. Consequently the chemical process in the soil was dominated by reduction and this process was the main development period for nodules of iron-manganese carbonate to form.

成土期处于末次冰期低海面、气候寒冷干燥期，土壤的化学过程是以氧化作用为主，是褐铁矿等氧化性矿物形成时期；冰后期海相层的沉积覆盖使土壤层进入成者阶段，土壤层的化学过程以还原作用为主，成岩过程是铁锰碳酸盆结核的主要生成期。

The Taihu Lake is situated in the centre of the dish-like lowlying land south of the Changjiang River, which was resulted from the two dynamic factors, the long-term ground depression at a rate of 0.4 mm/a, calculated from the archaeological data, and the rise of the postglacial sea level that was responsible for the formation of the high coastal plain on the east margin of the dish-like low-lying land.

本文从沉积学、地层学、地貌学、考古学和历史地理学角度，综合分析了太湖的成因和演变。认为地壳沉降与海面上升是构成江南碟形洼地的内外动力，为太湖的形成奠定了基础。全新世海侵最盛时，太湖海湾水深潮急、泻湖、滨海沼泽围绕海湾分布。随南部湾口沙嘴封堵，海湾趋于消失，陆地扩大，遗址增多。3700a来，海面回升，湖面逐渐扩展，形成现代太湖。
