海底洋脊 的英文怎麼說

海底洋脊

submarine ridges-
Cryptic species have been found in a wide range of marine organisms ; with majority of them are benthic invertebrates. in contrast, marine holoplanktons are thought to have lower diversity and slow speciation due to their strong dispersal potential. this paper reviewed studies on cryptic species and speciation in marine holoplankton. based on findings in 38 studied taxa, it was concluded that : 1 ) cryptic species are pervasive in marine holoplankton, suggesting holoplankton speciation was more active than previously thought ; 2 ) current morphospecies diversity is untenable to reflect true species diversity in marine holoplankton ; 3 ) geographic isolation may facilitate cryptic speciation of marine holoplankton. however, contribution of allopatric speciation is still questionable ; 4 ) ecological speciation may be the prevailing speciation mode in marine holoplankton. cryptic speciation in marine holoplankton is paradoxical, because rapid speciation under strong gene flow is countertuitive. solution of this paradox will help us gain deep insights of marine speciation and biodivesity
隱種廣泛存在於各類海洋生物中，尤其是底棲無脊椎動物.然而，海洋終生浮游生物由於具有較強的擴散能力，往往被視為生物多樣性低、物種形成慢.本文就海洋終生浮游生物隱種與物種形成的研究作一綜述.基於研究的38個種類，結果表明: 1 ）海洋終生浮游生物普遍存在隱種，其物種形成要比想象得快; 2 ）由於引種的廣泛存在，形態種生物多樣性無法反映海洋終生浮游生物真正的物種多樣性; 3 ）地理隔離有助於海洋終生浮游生物隱種的形成，但異域物種形成的作用仍值得商榷; 4 ）生態物種形成很可能是海洋終生浮游生物物種形成的主流模式.海洋終生浮游生物強基因流下快速的物種形成有悖于生物進化常理，解決該悖論將有助於我們對海洋物種形成和生物多樣性的理解The sea floor is spreading away from the mid-ocean ridges.
海底正在從大洋中脊擴張開來。Seamounts, underwater volcanoes, rift valley, the mid - ocean ridge, constitute a rich world of the ocean floor
海底山脈、海底火山、裂谷、大洋中脊等等，構成了豐富的海底世界。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。Students of the earth ' s mid - ocean ridge were closely following the incoming data from the galileo mission to jupiter, looking for more hints that an ocean of water - and with it, undersea volcanoes - could exist under the ice that covers jupiter ' s moon europa future interlanetary missions to europa and other promising sites seemed far more likely to find support than they had before mckay ' s announcement
研究地球大洋洋底形成的海脊的學者也在密切注視探索木星的伽利略號飛船傳回的最新信息：在木星的衛星歐羅巴表面冰蓋下面是否存在著海洋及海底火山的跡象，將來飛往歐羅巴及其他可能有生命的地點的星際航行任務可能會帶來更多的新發現，支持地外生命這一假設。The effects of ssc ( small - scale sub - lithospheric convection ) on seafloor topography are investigated by formulating a 2d thermal convection model that is parallel to plate motion
摘要根據建立的垂直於大洋中脊的二維熱對流有限元數值模型，採用常粘性以及與溫度相關的粘性兩種粘性結構對小尺度地幔對流對海底地形的影響進行了重新研究。Green fluorescent protein ( gfp ) was extracted from jellyfish ( aequerea victoria ) of ocean invertebrate. gfp can emit green fluorescent when it is illuminated by light of suitable wavelength. the emissions of fluorescence need not any additional factors, such as substrate, supplementary factor
綠色熒光蛋白（ greenfluorescentprotein ， gfp ）是來源於多管水母（ aequoreavictoria ）等海洋無脊椎動物的一種蛋白質，該蛋白質在體外經適當波長的光激發便發出綠色熒光，並且這種熒光的發射不需要任何底物和輔助因子的誘導。The rifts therefore represent divergent plate boundaries where seafloor spreading is taking place
這樣，大洋中脊就成為板塊分離邊界，海底擴張就發生在這里。The submersible " alvin " drops into the depths to shoot a towering structure at a recently discovered vent site in the mid - atlantic
