啮齿类

Any of several small ungulate mammals of Africa and Asia with rodent-like incisors and feet with hooflike toes.

非洲和亚洲的有爪类哺乳动物，有类似啮齿动物的门牙和类似有蹄动物的脚。

In the lower altitude of arid regions of China, with the change of landscape prairie, semi desert to desert, so were the relative distribution patterns of groups of distributional units, where hygrophilous species declined and xerophilous species increased.

基于GIS技术，以面积约为6 470 km2 的766个栅格收集我国干旱地区啮齿动物的二元分布数据，采用多元分析的分层聚类方法，依据欧氏距离平方值，将地理分布单元划分为若干个组。

Originally misclassified as rodents, rabbits belong to the order of Lagomorpha and are more closely related to ungulates such as cows and deer than rodents.

兔子原来被错误的归类为啮齿目动物，现在又归为与蹄类动物如母牛、鹿相近的复齿目动物。

Results Eight species belonged to three families, two orders of rodent animals and seven species of fleas were found in this area. Rattus losea and Xenopsylla cheopis were dominant species, R.flavipectus , R.norvegicus , Suncus murinus , and Banolicota indica were familiar species. The annual average density of rodents, the infected rate with flea of rodents, index of fleas, index of X.cheopis and free flea in room were 10.58%, 28.38%, 0.7916, 0.5702 and 0.0515 respectively.

结果 合浦县鼠疫疫源地的啮齿动物共有2目3科8种，以黄毛鼠为优势鼠种，黄胸鼠、褐家鼠、臭鼩鼱和板齿鼠为常见种；蚤类有7种，以印鼠客蚤为优势蚤种；年平均鼠密度、平均鼠体染蚤率、平均蚤指数和印鼠客蚤指数分别为10.58%、28.38%、0.7916和0.5702，地面游离蚤指数为0.0515。

Indirect transmission through the bite of a flea is the most common route of transmission between plague-infected rodents and humans.

经蚤类叮咬所致的间接传播是染疫啮齿动物与人之间最常见的传播方式。

It is still the case that very few studies on steroid actions in the nervous system are performed on nonrodent species, limiting the extrapolations that can be made to clinical situations.

很少关于甾体在非啮齿类动物神经系统上的作用被研究也是一个值得关注的问题，这限制了其在临床上的应用。

In an experiment with mice, the researchers identified and removed certain receptors on the olfactory bulb of their brains -- and the result was a batch of fearless rodents.

在一个老鼠实验中，研究者们定位并取走了老鼠大脑中相对应的嗅觉球状体--结果便是产生了这批英勇无惧的啮齿类动物。

The decrease of 11-HSD2 expression and the increase of 11(-HSD1 expression in the late gestation may allow GCs activation of more GR in the brain, thus permitting neuronal and glial maturational events.

但目前关于11β-HSD1在新生啮齿类动物脑内的发育规律及其与GR在神经元内分布的关系并不清楚。

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。
