活動洋脊 的英文怎麼說
中文拼音 [huódòngyángjǐ]
活動洋脊
英文
active ocean ridge-
Amore 2001 has successfully investigated the gakkel ridge and arctic ocean in vicinity of its geological and geophysical nature, as well as the nature of sea ice and biology in this area. the preliminary onboard petrology and bathymetry results show that the mantle beneath the gakkel ridge with low temperature has only encountered very low degree partial melting during the spreading and there is no any direct relationship between the crust nature and the spreading rate along the gakkel ridge in any simple petrologic way. mantle temperature and fracture zone density also play a major role on the crust nature, besides spreading rate
對所取得資料的初步研究表明gakkel洋中脊之下的地幔僅經受了較低程度的部分熔融，具有較低的溫度。 gakkel洋中脊處的地殼性質和巖漿活動與擴張速率之間不存在任何直接的巖石學相關性，擴張而導致的巖石圈頂部的冷卻並不是決定洋脊處地殼性質的最重要因素。地幔溫度和斷裂帶的存在與否及其密度對地殼性質具有重要的影響意義。Based on affirming mantle plume hypothesis, the authors introduce several 2d or 3d simulation experiments about ridge - plume ( hotspot ) interaction and some examples of hotspot - ridge interactions existing in the three oceans
研究洋脊熱點之間的相互作用對于揭示地幔動力學、熱點附近洋殼構造的演變以及與熱點密切相關的洋中脊處的巖漿熱液活動具有重要的意義。( 2 ) another interesting phenomenon is founded that the center of south asia high in the upper level of troposphere is stabile and nearly motionless during the processes of the westward extension of western pacific subtropical high, but its eastern ridge strengthens and extends eastward remarkably because of the anticyclone moves westward over the southeast japan, which may lead to the westward extension of subtropical high in the middle level of troposphere. ( 3 ) in the low level of troposphere, the north australia cold air activity plays an important role on the westward extension of subtropical high
（ 2 ）本文在研究副高西伸過程中指出，高層200hpa上日本東南部的高壓併入南亞高壓，導致南亞高壓脊的增強發展，對低層500hpa上副高的加強、西伸可能起到引導的作用；同時，對流層低層850hpa上孟加拉灣槽在副高西伸過程中加深，並在西伸脊點到達最西點的前4天強度達到最強，這為預報西太平洋副高的活動提供了參考。The summer rainfall anomaly of north china is closely related to indian low, west pacific subtropical high, westerly troughs and ridges in mid - latitude, south asia high, subtropical monsoon circulation and cold air activity on the corresponding period, and similar circulation pattern also appears in the preceding spring
結果表明： （ 1 ）華北夏季降水異常與同期印度低壓、西太平洋副高、中緯度西風槽脊、南亞高壓、副熱帶季風環流和冷空氣活動的異常都密切相關。華北夏季降水異常年春季的環流特徵與夏季類似。Through the systematic analysis and contrast studies on topographical environment characteristics of these typical regions, it is found that the hydrothermal activity only occurs under the circumstance of the particular topographical environment, though it distributes widely in the tensional tectonic environment, for instance, the mid - ocean ridges, transform faults zones, back - arc spreading basins and the modern marine craters regions
通過對典型熱液區地形環境特徵的系統分析和對比研究發現盡管現代海底熱液活動廣泛分佈在大洋中脊、轉換斷層、弧后擴張盆地等各種不同的張性構造環境及現代海底火山活動區，但也僅出現在特殊的地形環境條件下。分享友人
