种群比较

The least paedomorphic behavior pattern may be that of the basenji , bred in Africa to hunt alongside humans almost on a peer basis; this breed is often described as highly independent, neither needing nor appreciating a great deal of human attention or nurturing, often described as "catlike" in its behavior.

证明狗是从狼快速进化的一个例证是狗是性早熟或幼态持续的。跟大多物种一样，如小狼比起成年狼更偏向群居和比较少的具有支配力；因此，当进行优选时，不管是有意或无意的，最终的结果看来似乎是把这种幼体的特性带入了成年种群中，而非产生一个复杂的独立新行为。对包括人类自身的许多驯养动物皆是如此，人类很多特征与幼倭黑猩猩类似。这种幼态持续选择的结构自然是导致了幼体生理特征的保留。

Park area is very large, preserved relatively large cheetah population.

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。

In the process of calculation, by comparison theorem and strict calculation, some sufficient conditions for persistent and extinct of three populations are obtained.

推导过程中主要应用了比较定理，并且通过严密的计算，得到了三种群持续生存性和绝灭性的充分条件。

By analytical method and comparison theorem, some sufficient conditions for uniformly persistent of two populations and the whole system are obtained.

利用分析法和比较定理，得到两种群分别一致持续生存以及整个系统一致持续生存的充分条件。

The thesis also draw several conclusions as follows:(1) Orthogonal experiment design method can be viewed as a special case of genetic algorithm, i. e. a genetic algorithm with a fixed initial population, an oriented-mutation operator and one evolution epoch.(2) In terms of running steps, genetic algorithm is more complex than orthogonal experiment design method.

论文首次对正交试验设计法和遗传算法这两种独立发展起来的方法进行比较研究，提出(1)正交试验设计法是遗传算法的一种特例，即是一种初始种群固定的、只使用定向变异算子的、只进化一代的遗传算法；(2)遗传算法产生的优化解优于正交试验设计法产生的优化解，且遗传算法处理交互作用项的效率高于正交试验设计法；(3)遗传算法的步骤比正交试验设计法复杂，所需的试验次数也要多。

Wizard race after years on the development, divided into several more refined population, the upper part of Kuiersalashi genie out of, and claiming to be a "blood Wizard", and human alliances, and the rest is still sticking to its own ethnic purity, is the dark of night Wizard, which is also called purebred wizard .

精灵的种族经过上万年的发展，分为几个比较细化的种群，一部分奎尔萨拉斯上层精灵脱离了，并自称为"血精灵"，与人类结成联盟，剩下的仍在坚持自己种族的纯粹性，就是暗夜精灵，也被称为纯种精灵。

We compare allelic frequency data among and between these drainages, analyze genetic relationships between trout populations found east and west of the Continental Divide, and compare the genetic diversity found among Sierra Madre trout and Mexican golden trout found in the headwaters of the Sinaloa and Culiacan drainages.

我们要比较数据之间的关系，这些等位基因频率渠、鳟种群之间的遗传关系进行分析，发现东西大陆鸿沟比较遗传多样性卞耀武塞拉MADRE向墨西哥金鳟、鳟发现夺了罗亚和利亚坎渠。

The cox1nad4 sequences of eight cestodes samples(TPW2XX,DM4XX,TH5XX,DM6YY, MM11JT,DM15ZJ,TH28XX,DM31CZ) were obtained and their sequence length was 341bp.The eight cox1 sequences comparison revealed that they separated into four population.The difference among four population were bigger,12.9%～30.3%, 7～85bp.

获得8个代表性样品(TPW2XX，DM4XX，TH5XX，DM6YY，MM11JT，DM15ZJ，TH28XX，DM31CZ)的核苷酸序列，序列长度均为341bp，经核苷酸序列互对比较，结果显示它们存在四个种群，且四个种间cox1序列存在比较大的差异，为12.9%～30.3%，为7～85个碱基差异。

The resistance level of German cockroach from different sites was analyzed by average linkage method.

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
