查询词典 diversity

Immune function is a essential activity of white blood cells. It was puzzled for the diversity and complexity of immune response. Polarized immune response of immune cells was discovered 30 years ago, which facilitates the study on differentiation of lymphocyte. Recently recognition on multifunctional polarized immune response of lymphocyte and monocyte/macrophage would promote to elucidate the regulatory network of immune cells, diversity and complexity of immune response as well as the study on hemopoiesis.

A structure of space-time diversity virtual double-route weighting interference mitigating is proposed, and the corresponding practical algorithm is derived in detail using block matrix inversion formula and matrix inversion theory for mitigating interference signals from both other cells and other users of local cell in the DS-CDMA up-link communication case. Performances of such algorithm are thoroughly analyzed through simulation and analytical results. The up-link and down-link channel characters and their relationship of DS-CDMA communication system are thoroughly analyzed, and the relationship of space-time diversity weighting matrix between time division duplexing and frequency division duplexing these two different transmission ways is derived.

Biodiversity is one of the front areas of current biological research. The mechanisms of the formation, spatial distribution pattern, conservation and utilization of biodiversity have been an important area of biological and environmental research. In this study, through analyses of data about plant diversity, animal diversity, geographic factors, climatic factors, and energy factors by use of GIS software, statistic software and ecology software, the mainland of China was divided into 241 small districts of 2° by 2°. The environmental factors in each district were analyzed and isopleth maps of environmental elements were depicted.

生物多样性是当今生物学研究的热点问题之一，生物多样性的形成机制和分布格局以及保护利用问题一直是生物学和环境科学所研究的重要内容，本文由此出发，以中国陆地为研究区域，通过植物多样性数据、动物多样性数据、地理因子、气候因子、能量因子等资料，利用MAPGIS、MAPINFO等GIS软件，SPSS、DPS等统计学软件以及CANOCO等生态学软件，将中国陆地划分为241个小区，分析了各区内的环境特点，统计了各区内生物多样性的数量，并绘出环境因子等值线图，中国陆地种子植物科、属、种，裸子植物种、蕨类植物种、兽类、鸟类、爬行类、两栖类种数的等值线分布图，对中国陆地植物、动物多样性现状、分布格局及与环境因子的关系进行了研究。

The results revealed that nine of the fourteen Y-specific markers cannot be used for investigating the swamp buffalo Y chromosome genetic diversity because of the reasons specified below: three microsatellites markers (INRA008, UMN0103 and UMN0504) were single allele and monomorphism, three (UMN1113, UMN0304 and BC1.2) indicated three alleles respectively but mornomorphism, and the other three (UMN0920, UMN0307 and UMN3008) showed irregular ladder-like bands. Only the remaining five microsatellites (INRA124, INRA189, BM861, PBR1F1 and UMN2001) indicated polymorphisms, and thus can be applied to study the swamp buffalo Y chromosome genetic diversity.

结果表明，3个标记（INRA008，UMN0103和UMN0504）只有1个等位基因，表现为单态；3个标记（UMN1113，UMN0304和BC1.2）均为3个等位基因，但呈单态；3个标记（UMN0920，UMN0307和UMN3008）呈现无规律的梯状条带，所以这9个标记都不适用于水牛的Y染色体遗传多样性研究；只有5个标记（INRA124，INRA189，BM861，PBR1F1和UMN2001）具有多态性，表明适用于水牛的Y染色体遗传多样性研究。
