牦牛

Animals depicted are mainly deer, yaks, sheep and birds.

被描述的动物主要是鹿、牦牛、绵羊和鸟类。

The result shows clearly that the three fine group of yaks have high producing flesh performance.

说明西藏三大优良类群牦牛具有较高的产肉性能。

The mysterious snowy mountains, vast grassland, and groups of yaks form a unique plateau scenery.

神秘的雪山、辽阔的草原和成群的牦牛构成了独特的高原风光，充满了无穷的魅力。

With wild yaks roaming the landscape, an ecosystem is still intact.

一片有野牦牛漫步的土地是一片生态系统完好无缺的净土。

The distribution and the refluxing pattern of the venules in the pulmonary parenchyma on yak and sheep were described in the present study, and these contents provided the new data for the comparative anatomy.

本文报道了牦牛和绵羊肺脏实质内微静脉的系统的分支分布状况及回流方式，为比较解剖学增加了新资料。

The circular constructions of the smooth muscle cells were found on the cast surface of the venules in yak and sheep, and the number of the constructions would decrease gradually as the diameter of the venules decreased.

牦牛和绵羊肺微静脉铸型表面分布着由平滑肌束形成的环形缩窄，缩窄数目随着管径减小而逐步减少。

Standing on the plateau 4,500 meters above the sea, the protection station was established by volunteers of the Sichuan Provincial Council for the Promotion of Prelecting the Green River Environment during the past four years.

保护站周围是中国青藏高原特有的藏羚羊、野牦牛、藏野驴等野生动物最集中的分布地区和越冬地，保护站的建成，使反偷猎的队员在可可西里有了自己的家，也为野生动物提供了最安全的避难所。

It's held in such high regard that its fur is even used to decorate the sacred prayer flag poles,and yak butter is used as an offering to the gods.

人们把牦牛看得十分重要，把它的皮用来装饰神圣的幡杆，把它的油作为给上帝的贡品。

The results showed that the homologies of the partial exon Ⅰ sequences of the HSL genes between yak and cattle, zebu, buffalo, pig, human, mouse, and rat were as high as 99.8%, 99.6%, 97.4%, 90.6%, 88.4%, 83.5%, and 82.3%, respectively.

结果表明：牦牛与普通牛、瘤牛、水牛、猪、人、小鼠、大鼠7个物种HSL基因外显子Ⅰ部分核苷酸序列间保守性较高，同源性大小依次为99.8%、99.6%、97.4%、90.6%、88.4%、83.5%、82.3%。

Together with the cited sequences of other species (cattle, zebu cattle and buffalo), the molecular phylogenetic tree was therefore built to probe phylogenetic relationship between Bovine subfamilies, Total 5 variation sites were examined and two types of mutation, transition and transversion, were observed, with the overage percentage of nucleotide variation of 1.66%. It demonstrated the poverty of polymorphism at exon 5 of GH gene of three bovine species. There was only one missense mutation out of 5 mutation sites which led to the shift between leu and val amino.

结果表明，在雷琼牛、巴州牦牛和巴州蒙古牛中共检测到5个变异位点，核苷酸取代方式仅有转换和颠换，核苷酸平均突变率仅为1.66%，说明这3个牛种GH基因外显子5多态性较为贫乏；5个变异位点中仅有1个为错义突变，导致亮氨酸和缬氨酸的转换，但该突变在牛种中分布有差异。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
