蚁

The results show that the two kinds of basic ant colony algorithm have better performance than classical K-means algorithm and hierarchal clustering algorithm, the two kinds of extended algorithm have better performance than corresponding basic ant colony algorithm.

实验结果表明，两种基本蚁群算法的聚类效果优于经典的K_means算法和层次聚类算法；两种改进的算法又分别优于相应的基本蚁群算法，达到了算法改进的目的。

New World army ants and driver ants from Africa are swarm raiders, hunting above ground.

产自非洲的新世界军蚁和车蚁是群体狩猎者，在地面上四处出击。

The only use for males is to inseminate the queen; afterwards they are either driven out of the nest or killed.

雄蚁唯一的作用是使蚁后受精，之后它们就被驱逐出蚁巢或是被杀死。

It is improved to solve the prematurely and stagnation problems of traditional Ant Colony Optimization in the paper. First, mean value method is used to update pheromone to avoid premature convergence which leads to non-globally optimal solution. Second, Pheromone is updated by Best Track to speed the rate of convergence which will help to avoid locally optimal solution.

本文针对基本蚁群算法比较容易陷入早熟和停滞，对现有蚁群算法的信息素更新规则进行了改进，一是采用平均值法更新信息素，避免算法过早收敛于非全局最优解；二是采用最佳路径法更新信息素，可加快收敛速度，并使算法跳出局部最优解。

While her body rots encased in its external skeleton, her lingering scent misleadingly tells the colony that all is still well.

母蚁王的女婿们起初没有注意到她的死亡，虽然她的尸体在躯壳内腐烂，但她体内挥之不去的气味却误导了蚁群：一切安好如昔。

Future studies will focus on the odorous ant's genetics, in hopes of learning why urban life turns it into such a swarming bully—and how to stop it.

将来的研究将要把重点放在酸臭蚁遗传学上，希望能够了解为何城市生活环境使它们成为蜂拥而上的欺凌蚁，以及如何制止这种欺凌行为。

Yolk forming stage didnt exist in workers. AR played an important role in oogenesis of termites.

表明雄激素受体在白蚁的卵子发生过程中有重要作用，工蚁和繁殖蚁在卵子发生的早期是相同的。

This was the reason of no mature ovum in worker. But worker has a potential ability to turn into reproductives because of its complete differentiation stage and the growth stage in oogenesis.

由于具有完整的卵母细胞分化期和生长期，在巢群需要的情况下受调节可以进一步发育完成卵黄的形成，因此工蚁具有向繁殖蚁转化的能力。

These results provide a new proof of AR participating in the regulation of oogenesis development. 4. The immediate early-gene c-fos palys an important role in cell multiplication and differentiation.

这是我们首次在白蚁卵子发生过程中发现AR，并对非繁殖蚁和繁殖蚁生殖细胞发育的激素调节进行了对比，为进一步探讨AR在昆虫卵子发生中的调节机制提供了依据。

Meanwhile, the Palaeo species consists of Panto Palaearctic species, Mid Asian species, European species, Euro Central Asian species, endemic species, Mediterranean species, Euro Siberian species and Central Asian species, etc.

蚂蚁与人类有着密切的关系〔4～6〕，大多数蚁类有改良土壤、传播花粉、捕食害虫，作为食物和药物等用途，但也有部分蚁类对人类是有害的。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
