食草动物

However, not all herbivores have digestive systems that maximise fibre digestibility; only ruminants, camelids and very large hindgut fermenters achieve this.

对比而言，许多其它的食草动物，如前肠发酵的有袋类和小型的后肠发酵动物如兔子、田鼠和负鼠等，它们具备可以使植物纤维消化效率最大的消化系统，可以在食物中的纤维素含量非常高的情况下仍能处理大量的食物。

Carnivores have digestive systems dominated by the small intestine, which can be related to the generally high digestibility of their food. Omnivores have more complex gastrointestinal tracts, with a hindgut caecum in which some microbial fermentation takes place, and they have longer mean retention times of digesta.

食肉动物的小肠很发达，这可能与对食物的高消化能力有关；杂食性动物有更复杂的胃肠器官，其后端有可进行发酵的盲肠，消化物的平均滞留时间(meanretentiontimes ，MRTs)更长；最长的平均滞留时间见于食草动物，其消化道内高密度的微生物种群对不同滞留区内的消化物进行发酵。

"That you can turn your back on Kenya and go live on some terraformed planetoid, just because you want to wake up to the sight of a handful of animals grazing."

&你把肯尼亚背弃了，然后再搬到一颗什么改造成地球的小行星上去住，其实就因为你想要每天早上醒来时能看见一群食草动物！&

HereⅠuse published literature data on the late Palaeolithic of Lake Baikal and Altai Mountains region in Russia to map environmental changes through molar crown height, diet and body size in large h.

利用已发表的俄罗斯贝加尔湖和阿尔泰山区域旧石器时代晚期的文献资料，通过对大型食草动物臼齿齿冠高度、食性和体型大小的分析，绘制了环境变化图。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
