外陆架 meaning in Chinese
outer continental shelf
Examples
- In this paper , ree are used to trace the core q43 sediment samples from the outer shelf of east china sea
本文通过对东海外陆架q43柱样沉积物进行稀土元素分析，利用其稀土元素组成特征来讨论物质来源。 - The upper layer sediment of core q43 in the outshelf of the southern east china sea shows that it is the regressive sequence of littoral facies to offshore facies and of representative significance
以q43岩心为代表的东海南部外陆架上层沉积物，是末次冰期海退层序中，滨岸相-滨外浅水相沉积。 - Clay minerals are of illite , chlorite , kaolinite and smectite assemlblage . the content of illite is very high and its crystallinity index is high too , which indicate the cool and arid climate condition in the time of sediment conformation
粘土矿物组合为伊利石、绿泥石、高岭石和蒙皂石，伊利石含量占绝对优势，其结晶度指数( hw )较高，反映东海南部外陆架粘土形成于寒冷干燥的气候环境。 - Results as following : in the east china sea and the yellow sea , zooplankton showed higher diversity in the low latitude and warm species occurred mainly in the south of 31 n , five communities were distinguished by twinspan method , based on data of species composition and environmental factors . they are : i ) yellow sea neritic community ( f ) with indicator species of labidocera euchaeta in autumn and centropages mcmurrichi in spring ; ii ) yellow sea central community ( hc ) with indicator species of themisto gracilipes , calanus sinicus and euphausia pacifica , the latter two species occurred only in autumn ; iii ) east china sea continental shelf mixed water community ( k ) with indicator species such as rhincalanus cornutus and pterosagitta draco which were confined in waters with high temperature and salinity , iv ) yellow sea and east china sea mixed water community ( he ) and v ) east china sea inshore mixed water community ( m )
根据twinspan等多元分析结果，比较各组群的浮游动物种类组成和环境特征，可将东、黄海浮游动物群落分为5个，黄海沿岸群落（ f ） ，指示种秋季为真刺唇角水蚤，春季为墨氏胸刺水蚤；黄海中部群落（ hc ） ，指示种以细长脚虫戎为主，秋季还有中华哲水蚤和太平洋磷虾；东海外陆架高温高盐群落（ k ） ，指示种为角锚哲水蚤、飞龙翼箭虫等多种狭布型暖水种类；黄东海交汇区群落（ he ）和东海近岸混合群落（ m ） ，两群落包含多种生态类型种类，其中温带近岸低盐种在he中较多，广布性暖水种在m群落中较多。 - Comparison of the characteristic parameters of immobile elements , such as ree , sc , th , ti etc and of the characteristics of sedimentology and mineralogy comes to a conclusion that the provenance of the sediment is different in the last glacial maximum and in the sub - interglacial stage , and they have the traits of mixed source . during the last glacial maximum the sediment in the outshelf of the southern east china sea was affected weakly by changjiang river and they are probably derived from the coast mountains of zhejiang - fujian province , which are near the southern east china sea
通过对东海外陆架样品的稀土元素和sc ， th ， ti等不活泼元素地球化学物源示踪指标对比，再结合沉积学和矿物学特征，判断末次盛冰期与盛冰期以前的沉积物具有不同的物质来源，不同时期的沉积物都具有混合物源的性质，盛冰期东海南部外陆架沉积物受长江物源影响较小，可能来源于距东海南部较近的浙闽沿海山地。
