鸟类

A member of the subphylum Vertebrata,a primary division of the phylum Chordata that includes the fishes,amphibians,reptiles,birds,and mammals,all of which are characterized by a segmented spinal column and a distinct,well - differentiate d head.

脊椎动物脊索动物门的一个原始分支，属于脊椎动物分门的一种动物，包括鱼类、两栖动物、爬行动物、鸟类和哺乳动物，其共同特征是都有节段的脊柱和很明显的、分化的头部

Peacocks are classified in the phylum Chordata, subphylum Vertebrata, class Aves, order Galliformes, family Phasianidae.

孔雀被认为是脊索动物类，脊索动物亚门，鸟类。

But many migrant birds fly only at night and so cannot use the Sun as a compass.

但是，许多迁移鸟类仅在夜间飞行，因此，不能利用太阳作指南针。

Gecko danger, to escape from the end, the tail can also regeneration; spiders can not only foresee the impending storm front, but also quickly erect个Net knot to prevent cross-Net torn by wind and rain and no home to return to; fly bats were not birds belong to animals, it can rely on their own issued ultrasonic reflectivity of the target to determine the target insects are still obstacles; sundew, rainbow grass these plants were able to "kill" small insects as their own "food"......

壁虎遇到危险，脱尾逃生后，尾巴还能再生；蜘蛛不但可以预知暴风雨来临，而且还赶忙结个竖网，以防横网被风雨扯破后无家可回；会飞的蝙蝠居然不属于鸟类动物，它还能靠自身发出的超声波对目标物的反射来确定目标是昆虫还是障碍物；毛毡苔，彩虹草这些植物居然能"捕杀"小虫子作为自已的"食物"。。。。。。

The distribution of supertramp bird species on islands also supports the theory that communities are structured by competition.

岛屿上超飘流的鸟类物种的分布也支持了该理论，即竞争导致了群落的结构化。

It very important to syncretize the community ecology and landscape ecology by the spatial distribution and comparisons in scale. The result show bird habitat selection is affected by the temporal and spatial scale and heterogeneity.

生物分布的空间异质性和尺度的比较研究是群落生态学和景观生态学交叉研究的重要切入点，本研究认为，鸟类的生境选择研究应该是时间、空间尺度以及异质性研究的综合。

Birds have complex acoustic signals ,their unique vocal organs－syrinx are special species.

鸟类是具有复杂声行为的动物，其拥有特殊的发声器官--鸣管。

It consists of the retina,the optic tectum,the thalamic nucleus and the telencephalic ectostriatum.

在鸟类离顶盖通路中，视觉信息从视网膜传送到视顶盖，再经丘脑圆核到外纹体。

The brain of a bird has well developed cerebral hemispheres, cerebellum, and midbrain tectum.

小脑发达且体积大，这与鸟类飞翔动作及其协调密切相关。

Aves and teleost hemoglobins tend to select residues with larger side chains.

鸟类和硬骨鱼类血红蛋白倾向于选择侧链更大的残基，这些大侧链残基主要分布于分子表面和亚基之间的界面，导致四级结构的差异。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
