研究动物

Stephen Wroe, a paleontologist and mammal expert at the University of Sydney in Australia, led the study.

同样地，研究结果还显示，这些有袋的食肉动物在大约3万年以前就已经漫步在澳大利亚的土地上了，那时它们撕咬猎物的能力就差不多已经和现在的狮子一样强大了。

该站涵盖了生物总论、生命起源、生物学研究、生命物质、生物机能、个体发展、群体发展以及生物世界等多个部分，涉及了史前生物、植物、动物、昆虫、微生物领域。

We think our animals were basically isolated from the rest of what was going on in Pangaea by this large desert climate.

希德博士和他的研究小组认为，这两种新的古代两栖类动物在泛古陆中部的尼日尔是被气候条件孤立隔离的。

Fifteen healthy male adult rhesus were randomly divided into control group and experimental groups(+15Gx、+18Gx and +21Gx group),and respectively underwent corresponding parabolic G curve in animal centrifuge.

实验选用9 只健康雄性成年恒河猴随机分为对照组和实验组（+15Gx 组、+18Gx 组和+21Gx组），分别在动物离心机上承受相应峰值的抛物线形过载曲线作用，然后解剖取材固定用以病理形态学方面的研究；同时取尿液，立即送检。

Paradise fish has regular and ritual process of agonistic interaction which can be separated into three phases, namely, initial phase, threatening phase, and fighting phase. In initial phase, two fish encounter and swim close to each other. In threatening phase, two fish display shaking, head-tail swimming to threat their opponent.

目前已知敌对行为牵涉到中枢神经系统的调控，尤以中枢神经系统中的血清张力素神经元被许多研究学者指出是与敌对行为调控相关，但尚未确定血清张力素神经元在动物进行敌对行为过程中是如何的参与其中调控。

The single and combined toxicity effects on Paramecium caudatum, Dugesia japonica and Cipangopaludia cathayensis exposed for special period (12, 24, 48 and 72h) in different Pb(superscript 2+) and Cd(superscript 2+) concentrations were studied by using toxic experiment techniques.

在特定时间(12、24、48、72h)内，研究了Pb(上标 2+)和Cd(上标 2+)对草履虫、三角涡虫和中华圆田螺3种水生动物的单一和联合毒性效应。

More and more studies have been carried out on population genetic structure of rotifer population and gene flow by molecular technologies to assess the effect of cyclic parthenogenesis and resting egg bank on rotifer's genetics and evolution.

由于循环孤雌生殖和休眠卵库的存在，使得轮虫种群内的遗传变异和种群间基因流模式有别于其他动物。目前，国外有关轮虫分子遗传和进化的研究还刚刚起步，国内还没有这方面的报道。

After full-term pregnancy and parturition 2* and C3 gave birth to 7 and 8 baby mice respectively.

通过该研究，我们建立了在乳腺中表达人瘦蛋白的转基因动物模型，转基因得到较高水平的表达。

The range of sound pressure measurements was 0.15–105 Pa. A series of consecutive measurements were made at intervals of 52.5 s. The wavelength of 80 kHz frequency, although not ideal for investigating mesozooplankton, was chosen because we were initially studying patchiness of

健全的压力测量范围为0.15-105宾夕法尼亚州的连续测量了一系列在52.5秒的时间间隔作出80千赫频率的波长，虽然不是理想的调查浮游动物，是因为我们选择了最初的研究斑块

This model can be used to study the pathogenesis of radiation-induced cognitive changes.

这种动物模型可用于放射治疗诱发的认知功能障碍的病理机制的研究。

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。
