多样性

Along with the aggravation of market competition, China Unicom Anhui Brach is facing with more and more pressures. On the one hand, the internal pressure of cost pressure is greater and the promulgation of Saipan Si bill also makes stricter request for internal cost control. On the other hand, with commercial service of 3G approach gradually, the variety of the service brings the variety of the business pattern, which request support system to be more suitable and facil.

随着市场竞争格局的进一步形成，电信企业间的竞争不断加剧，安徽联通面临着更多的内外部压力：对内，成本压力越来越大，塞班斯法案的颁布对内控提出严格要求；对外，3G的商用日益临近，业务的多样性带来运营模式的多样性，这些都对支撑系统提出了更高的要求。

In view of the fact that the O. t. dybowskii are in imminent danger, first, must take importance to protection of wintering areas;Next, must try our best to protect the important breeding areas;Finally, establishes a population including existing genetic diversity for reintroduction, thus enable it to get rid gradually is in imminent danger, achieves the bustard species protection the goal.

鉴于东方亚种的濒危境地，首先，要重视越冬地的保护；其次，要保护好重要繁殖区：最后，建立一个拥有现有遗传多样性水平的迁地保护种群，既可避免其遗传多样性的进一步丧失，又可为扩大野外种群的规模奠定基础，从而使其逐渐摆脱濒危境地，达到大鸨物种保护的目的。

This paper agrees on the view that Byzantium Miniature is diverse, further elaborates the causes of the diversity.

根据本文观点首先肯定拜占庭细密画风格是具有多样性特点的，进而探寻其多样性风格形成的原因。

In this algorithm, first, a crowed comparison operator is used to sort and select individuals according to the characteristics of multi-objective optimization. Then, a non-uniform mutation operator is applied to the observation populations to preserve the convergency of the solutions and to improve the precision of local search. Finally, a diversity-preserving operator is employed to delete the observation populations for the purpose of preserving the solution diversity.

首先，根据多目标优化特点，使用多目标密度比较算子对量子种群进行排序和筛选；然后，应用非均匀变异算子对观测种群进行变异以保持解的收敛性并提高局部搜索的能力；最后，使用多样性保持算子对观测种群进行删减以保持解的多样性。

Except that the specifications of the single-objective real-valued quantum-inspired evolutionary algorithm are kept, the proposed algorithm has three main features to enhance the RQIEA. First, the crowed comparison operator is used to sort and select individuals in multi-objective sense. Second, the non-uniform mutation operator is applied to improve the precision for local search and to preserve the convergency for the solutions. Third, the diversity preserve operator is proposed to maintain the diversity.

该算法除保留求解单目标优化问题的实值量子演化算法的特点外，还有三个主要特征：首先，根据多目标优化特点，使用多目标密度比较算子对种群进行排序和筛选；其次，应用非均匀变异算子保持解的收敛性和提高局部搜索能力；再次，使用多样性保持算子来保持解的多样性。

The reason probably is that the two classification systems are not concordant with each other.

但植被景观多样性与土壤类型多样性之间不存在显著的线性相关或秩相关关系，这可能是由于二者的分类体系不吻合。

By using the Neighbor-joining method, a dendrogram was obtained based on genetic distances. The bootstrap values were evaluated for each crunode of the dendrogram by means of bootstrap test. The results showed that the mean heterozygosity of the whole native egg-typing duck breeds population was lower than those of native chicken breeds and goose breeds, suggesting that the genetic diversity in those duck breeds population is relativly rare and should be strengthened. The rank of the heterozygosity was consistent with that of the polymorphism information content. The results of the genetic distances between them indicated that the differentiation occurred long time ago. In the dendrogram, Weishan pocked, Youxian pocked, Huainan pocked, Guangxi pocked and Jingjiang pocked were classified into one goup, Chaohuand Enshi pocked were the second group, Liancheng white, Putian black, Jinding, Shanma, Sansui and Shaoxing were the flnra grong.

结果表明：我国所有蛋鸭品种全部群体的平均杂合度较低，其遗传多样性相对贫乏，各保种场要加强多样性的保护；各品种的平均多态信息含量的高低与群体平均杂合度的顺序完全一致；遗传距离的计算说明了13个品种的遗传距离较远，分化时间较长；13个地方蛋鸭品种被聚类为3个类，微山麻鸭、攸县麻鸭、淮南麻鸭、广西小麻鸭、荆江麻鸭聚为一类；巢湖鸭和恩施麻鸭聚为一类；福建省的鸭种连城白鸭、莆田黑鸭、金定鸭、山麻鸭与三穗鸭、绍兴鸭聚为一类。

The diversity and evenness are low when the MQCIs are less than 15% and greater than 45%, and reach to high when MQCI in the middle of 15% and 45%. The relationship between MQCI and richness index can be best presented by a cubic equation, and no apparent trend can be found when MQCI is greater than 20%.

多样性和均匀性指数与草甸质量盖度指数之间关系的可以分别用二次方程式进行描述，当高寒草甸的草地质量指数在15%以下时，多样性和均匀性指数均较低，介于15%～45%之间时两者都很高，大于45%后，有下降的趋势；物种丰富度与草甸质量盖度指数之间的关系可用三次方程式进行描述。

Six populations of Cypripedium flavum were studied on their genetic diversity, genetic structure, and clonal diversity in Zhongdian County, Yunnan Province (South-west China).

采用AFLP分子标记方法对云南中甸的6个黄花杓兰居群进行了遗传多样性水平、遗传结构及克隆多样性研究，其中两个居群用样方取样法分析其克隆空间结构。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
