查询词典 sea level

Study shows that environment evolution and eustatic change of Holocene in this area may be divided into 6 stages:① early stage of early Holocene, 9 100~10 900 aBP,when sea level was low and this area was an oxidizing environment or oxidizing-reducing transition environment;② late stage of early Holocene, 8 000~9 100 aBP, sea-level rising,...

研究表明，本区全新世环境演化分为6个阶段：①早全新世早期，10900~9100aBP，海平面较低，尚未淹没本区，为近岸氧化环境或氧化—还原过渡环境；②早全新世晚期，9100~8000aBP，海水上涨，本区时淹时退，为浅海或潮坪环境，生物钻孔发育；③中全新世主体，8000~4150aBP，海平面快速上升，完全淹没，Fe2+/Fe3+介于0.7395~1.9123之间，为全新世中最高段，表明还原程度强、全球气候变暖；④中全新世后期，4150~2850aBP，海水有所下降，仍为浅海环境，Fe2+/Fe3+较高，多在1.0以上；⑤晚全新世，2850~1310aBP，海平面进一步下降，本区时常暴露，其中2150~1310aBP以还原环境为主，为潮下带，2150~2850aBP以氧化—还原过渡环境为主，为潮间带；⑥1855AD以来，海平面基本稳定，稍有上升，为现代黄河三角洲沉积时期。本区全新世至少存在5期冷热交替的旋回性气候变化。

Miller, a paleobiologist and professor of geology at the University of Cincinnati, says the new study is striking because it establishes a clear relationship between the tempo of mass extinction events and changes in sea level and sediment: Over the years, researchers have become fairly dismissive of the idea that marine mass extinctions like the great extinction of the Late Permian might be linked to sea-level declines, even though these declines are known to have occurred many times throughout the history of life.

&阿诺德一Miller表示，与古地质学教授在辛辛那提大学说，新研究是惊人的，因为它确立了明确的关系节奏的大规模灭绝事件和海平面变化和沉积物：&多年来，研究人员已成为相当不屑一顾的想法，海洋生物大灭绝一样伟大的濒临灭绝的晚二叠世可能与海平面下降，即使这些下降是众所周知的已经发生很多次整个生命的历史。清楚这项研究的关系文件将促使许多人重新考虑其以前的意见。

After analyzing the impacting factors of natural vulnerability along the Pearl River mouth, the paper divides the coastline of approximately 412km into 25 15-minute gird cells. For assessment purposes, the six variables including geography, relative sea-level change, average tide range, regional slope, shoreline erosion or accretion rates and tropic cyclone impacting frequency are selected as assessed variables. Once each section of coastline is assigned a risk value for each specific data variable, the costal vulnerability index can be useto calculate the natural vulnerability of the areas along the Pearl River mouth. After that, the paper develops a database for assessment of coastal vulnerability to sea-level rises and protracts a 1:2,000,000 vectors CVI map of the coastlines along the Pearl River mouth.

为了探讨不同海岸带对未来海平面上升的自然脆弱性，本文以珠江口沿岸作为研究个案，在分析珠江口沿岸自然脆弱性的影响因子的基础上，把珠江口沿岸412km岸线划分为25个15′×15′的网格单元，选取了地质、海平面上升率、平均潮差、区域海岸坡度、海岸侵蚀/堆积率、热带气旋影响频率6个评价指标，应用CVI指数评价公式对珠江口地区进行海岸脆弱性评价，并建立海岸脆弱性评价数据库，绘制了珠江口沿岸1：2，000，000的数字化CVI图。

The results show that at sea level, coolant flow rate affects the plug pressure, heat flux and temperature; at design operating condition, coolant flow rate has no effect on pressure and heat flux on the plug wall. With the same coolant flow rate, plug temperature at sea level is higher than that at design operating condition; under the same operating condition, ramp temperature is higher than the plug base temperature.

计算结果表明：地面工况下，冷却剂流量的改变对塞锥和塞锥底部壁面的压强、热流密度和温度的影响较大，高空环境下，冷却剂流量的改变对塞锥和塞锥底部壁面的压强、热流密度的影响较小；在冷却剂流量相同的情况下，塞锥和塞锥底部在地面工况下的壁面温度要远高于在高空环境下的温度；在相同工况和相同冷却剂流量的情况下，塞锥壁面上的温度要远高于塞锥底部壁面上的温度。

Since 1993, data from satellite altimeters, used to measure sea level, have shown that the worlds oceans have risen by 3.2 centimeters, or 1.26 inches, per decade (plus or minus 0.4 cm).Although 3.2 cm may appear to be only a slight increase, it is twice as large as sea level rise in the last century.

自从1993年以来，人造卫星测高计（常常被用来测量海平面高度）提供的数据就显示，每10年内，世界上各海洋都升高了大约3.2厘米或是1.26英寸（含正负0.4厘米）；虽然区区3.2厘米看起来只是轻微的升高，但这几乎是上个世纪海平面升高的两倍。
