群落

Collembola, Nematoda, Acariformes and Oribatida were the dominant groups, accounting for 82.3% of the total individuals.

温室土壤动物群落的垂直分布规律明显，具有一定的表聚性，0~5cm、5~10cm土层分别占土壤动物总数量的75.4%和14.6%。

Result In subalpine coniferous forest in western Sichuan, the Nematoda, Acarina and Collembola were the dominant groups of soil animal community and Diplopoda, Harpacticoida, Rotatoria, Enchytraeidae and Diptera were the frequent groups.

结果］川西亚高山针叶林土壤动物群落以线虫纲、蜱螨目、弹尾目为优势类群，以倍足纲、猛水蚤目、轮虫纲、线蚓科、双翅目幼虫等为常见类群。

Across the altitudinal gradient, a total of 12635 individuals belonging to 6 phyla, 15 classes and 33 orders were collected. With increasing altitude, the density of soil fauna decreased, but the group number was less affected. There was a higher co-occurrence of soil faunal communities along the altitudinal gradient, and Nematoda, Acarina, and Collembola were the dominant groups. Below the altitude 370 m, the Shannon-Wiener index, Pielou index, and Margalef abundance index increased with increasing altitude; while above the altitude 370 m, the Shannon-Wiener index and Pielou index decreased but the abundance index increased after an initial slight decrease.

结果表明：土壤动物密度随海拔升高而下降，类群数受海拔影响较小，各海拔群落的共有度较高，优势类群基本均为线虫、蜱螨目和弹尾目；Shannon-Wiener指数、Pielou均匀度指数及Margalef丰富度指数仅在海拔370 m以下随海拔升高而增加，而在海拔370 m以上，Shannon-Wiener指数与Pielou均匀度指数下降，丰富度指数在略有下降后再次上升。

It is, hence, suggested that structure of the nematode community is a potential indicator of changes in soil quality and ecosystem.

因此，土壤线虫群落结构对土壤质量或生态系统的变化具有很好的生物指示作用。

Diversity index of vertical distribution of soil nematode community was influenced by different irrigation treatments.

不同灌溉处理对土壤线虫群落生物多样性的垂直分布有一定的影响。

The collection of people, hardware, and software -- the multi-access computer together with its local community of users -- will become a node in a geographically distributed computer network.

人、硬件和软件作为多用户计算机连同其用户的区域群落，它们聚合起来将成为地域性分布式计算机网络的节点。

Only the most northerly group has retained their language and ethnic identity into the 20th century.

只有最北部的群落将他们的语言和种族身份保留到了20世纪。

This paper summarizes some molecular ecological techniques used in the studies on microbial community structure of oil reservoirs in China, including 16S rRNA gene sequence in the Daqing Oilfield and the northwestward oilfields, 16S rDNA of T-RFLP in the Shengli Oilfield and DNA gene track examination technology in Jilin oilfields, and points out some questions and suggestions for future studies.

本文较系统地总结了我国利用分子微生物生态学方法研究油藏微生物群落结构的进展，其中包括大庆油田和西北部油田的16S rRNA基因序列分析，胜利油田16S rDNA的荧光标记末端多形态限制性片断分析技术，以及吉林油田应用的DNA基因跟踪检测技术，并指出了存在问题和研究方向。

To explore the functions of SPANXA1 in cancerous phenotypes CL1-5 cells were transfected with a SPANXA1 expressing vector and evaluated by cell proliferation, cell migration, Matrigel invasion and colony formation assays in vitro as well as mouse metastasis assays in vivo. The results indicated that the induction of SPANXA1 could reduce cell invasiveness. In the other hand, immunostaining showed that SPANXA1 was predominately located at the nucleoplasm.

经RT-PCR验证得知SPANXA1在CL1-0的表现量比CL1-5多100倍以上，於是我们将SPANXA1转染在CL1-5细胞株中，并测量活体外的细胞生长速度试验、细胞迁徙实验、Matrigel侵袭实验、癌细胞群落形成实验及小鼠活体内细胞转移能力，探讨SPANXA1对癌细胞性状的影响，结果发现增加SPANXA1会降低癌细胞的转移能力，在另一方面，我们利用免疫萤光染色法侦测出SPANXA1是存在於核质中，并以西方点墨法再次证实SPANXA1是存在於核质中。

The reasonable thinning is very significant in theory and practice to improve the nutation space of canopy and conditions of water and nutrition underground, to guarantee individual and colony development and to improve forest community biomass and productivity.

合理的抚育间伐对改善森林林冠层的营养空间以及地下水肥的供应条件，保证林木个体和群体生长，充分发挥森林群落的生物量和生产力具有重要的理论和实践意义。
