查询词典 populations

For larger populations, there are two methods of surveillance that are most applicable: systematic random sampling and cluster sampling.

对于数量较多的人群，有两种最适用的监督方法：系统随机抽样和分组抽样。

A multi-agent/mobile-agent platform, which stems from computational infrastructure agent grid has been designed and prototyped. As a node of grid, on each platform simulations of evolutionary processes of multi-nodes synchronous processing associated with individual inter-generation communication and individual migration between elementary populations can perform coadaptation based cooperative coevolution of the multi-population as a whole system, such as the case of the three species ecological system.

各网格节点的计算环境都支持单/多种群进化过程仿真，可分别执行不同的演化算法，模拟特定参数集合制约下的协适应共进化过程，如三物种生态系统的可持续进化，已由多节点同步执行算法、代间通讯及子群间个体转移进行演化过程仿真。

It is suggested that it is better to indicate the variability within breeds by average heterozygosity based on microsatellite polymorphisms, which showed high polymorphisms and codominant inheritance of the markers, where as differences between populations and even specific characteristics with in a population are reffected clearly and directly by RAPD.

由于微卫星标记多态性程度高且等显性遗传，因而通过它计算杂合度可以较好地反映群体内的变异；RAPD则在反映群体间的区别甚至某一群体的特征时可提供明确而直接的信息。

It is just a purely coincidental occurrence that we see in all populations around the world. You can rest assured that this is so.

这只是一个纯粹的巧合罢了，我们查看世界各地的所有这些FOP人群，你可以放心，这是事实。

In Florida, where 17 percent of the population is now over 65 years of age, Mr. Colburn estimates that by 2025, a third of the state's counties could have senior populations larger than 30 percent.

Colburn 先生的研究还表明，目前佛罗里达州17%的人口是65岁以上的老人，而到2025年时，在全州1/3的县里，65岁以上的老龄人口就会超过30%。

We find him cold-bloodedly ordering a hundred hostages executed for every German occupation soldier killed;dictating the massacre of Italian officers who had turned their weapons against German troops in 1943;ordering the liquidation of Red Army commissars,Allied commando troops,and captured Allied aircrews;in 1942 he announced that the male populations of Stalingrad and Leningrad were to be exterminated.

我们可以看到他曾经冷血的下令处决一百个人质来为每名死难的德国士兵偿命；他命令对意大利官员进行大屠杀，因为这些人在1943年掉转枪口对准了德军；他下令消灭红军政委、盟军的突击队员和被俘的盟军机组人员；他在1942年宣布，斯大林格勒和列宁格勒的全部男性都将被清除。

In particular, transgenic maize expressing higher levels of a protein designed to exhibit increased toxicity toward Coleopteran pests deliver superior levels of insect protection and are less likely to sponsor development of populations of target insects that are resistant to the insecticidally active protein.

特别是，设计一种蛋白以表现出对鞘翅目害虫提高的毒性，表达较高水平的这种蛋白的转基因玉米表现出优越的昆虫防治水平，并不太可能引起产生抗所述杀虫活性蛋白的目标昆虫群体。

The largest ethnic group are the Fang, though there are also numerous Bubi and smaller populations of Bisio, Bujeba, Ndowe, Combe and Annob nese people.

人数最多的种族是＂方＂，＂布比＂人口也很多，再下来数量较少的种族是＂拜斯克＂人，布也巴人，多威人，肯博人和阿诺邦人。

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。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
