deep sea sediment meaning in English
深海沉积物
Examples
- More psychrophiles isolated from antarctic samples than that from deep sea sediments
与深海沉积物相比，嗜冷菌在南极样品中所占的比例较大。 - The profile of microbial community structures in different deep sea sediments was evaluated and the interaction between microorganisms and environment was analyzed by culture - independent molecular phylogenetic methods . psychrophilic and psychro - tolerant bacteria were cultured and used for screening the cold - active enzymes
此外，本文还对采集自太平洋的深海沉积物和南极、北极区域的样品进行了低温微生物的分离培养及低温酶的筛选与性质分析。 - The global change study is one of the most spectacular and interesting environment scientific questions in the 1990 s . the message of global change stores in tree rings , ice core , loess , underground water , lake sediment and deep sea sediment , all these proxies record the information of global change . with the advances in stable isotope techniques , the isotopic tracer records the message of climatic variation and becomes a powerful tool that can understand paleoenvironment reconstruction and modern environment changing
全球变化研究是90年代以来最为引人注目和关切的环境科学问题之一。全球环境变化的信息储存于树轮湖泊冰芯黄土地下水和海洋沉积物等载体中，随着稳定同位素技术的发展，同位素示踪剂指示环境变化的信息，成为了解古环境再造和现代环境信息变化的一个强有力的工具。 - In this study , we investigate the microbial diversity of deep sea sediments and analyze the characteristic of substance and energy conversion driven by microorganism in " warm pool " area for the first time . samples including deep sea sediments of the pacific ocean and other environmental samples from polar region were collected and analyzed
本论文首次对“暖池”区海底沉积物中的微生物进行了分子生态学研究，分析了微生物多样性，对由微生物参与的物质能量循环特征进行了探讨，为研究深海生物圈在地球圈层相互作用中的地位提供了参考资料。 - Some characteristics of cold - active protease and chitinase were analyzed then . microbial 16s rdna ( ribosomal dna ) clone libraries of deep sea sediments were constructed and studied by pcr - rflp ( restriction fragment length polymorphism ) and phylogenetic analysis based on 16s rdna sequences . the microbial diversity and community structures of deep sea sediments collected from two different sea area including the west pacific " warm pool " and the east pacific " manganese nodule " area , as well as the interaction between microbial community and environment , were analyzed based on these studies
通过构建沉积物中微生物16srdna克隆文库，采用pcr - rflp分析、 dna - dna杂交、 16srdna序列测定以及系统发育分析的方法，研究了两太平洋“暖池”区和东太平洋“结核”区两个不同海区深海沉积物中的微生物多样性和群落结构特征及其与环境的相互关系，得到了一些与“暖池”区环境特点紧密相关的新发现，新认识。
