This paper mainly investigated the effect of maternal undernutrition during late pregnancy on the levels of hormones which take the somatotropic axis as the center in ewes and lambs, the expression of partil hormones'mRNA and the gene localization in tissue cells on the basis of animal nutrition, endocrine physiology and by modern molecular biology technique.

中文摘要：本研究依据动物营养学和内分泌生理学理论，应用现代分子生物学技术对限制营养的妊娠母羊和羔羊以内分泌生长轴为中心的激素水平变化和部分激素及其受体mRNA表达水平的影响以及在组织细胞中基因表达定位规律等进行研究，进一步探究反刍动物补偿生长的机理，为更科学地将动物的补偿生长能力应用于畜牧业生产上奠定理论基础。

This study mainly investigated the effect of maternal undernutrition during late pregnancy on the levels of hormones which take the somatotropic axis as the center in ewes, the expression of partil hormones'mRNA and the gene localization in tissue cells on the basis of animal nutrition, endocrine physiology and by modern molecular biology technique. The experiments explored the mechanism of restriction and compensatory in order to pave the way for applying compensatory growth for animal husbandry scientifically.

本研究依据内分泌生理学和动物营养学理论，应用现代分子生物学技术系统研究了限饲及补偿生长对母羊生长轴激素基因表达水平的影响以及部分激素在母羊组织细胞中基因表达定位规律，进一步探究了绵羊补偿生长与内分泌生长轴的关系，为更科学地将动物的补偿生长能力应用于畜牧业生产上奠定理论基础。

So in this work, we focused no the following aspects: 1 The ecological effect of ephemeral resource on the rodent community; 2 The ecological isolation and coexistence mechanism for the sympatric species; 3 The effect of ecological process in a regional scale on the specie richness to investigate the community Patterns and limitation Mechanism of the desert rodents in this region, the main results and conclusions were as follows

为此，本工作立足于以下方面：（1）限制性资源对荒漠啮齿类动物群落的生态效应；（2）同域物种的生态分离与共存机制；（3）局域尺度的群落过程对区域物种丰富度的影响；对该地区的荒漠啮齿动物群落格局及其相关的制约机制进行了研究。主要研究结果和结论如下

Zoobenthos are also used as biological monitors of the environmental health of lakes and rivers. Theories and methods of the secondary production of zoobenthos were reviewed with emphasis on the calculation of secondary production, P/B coefficient and factors to affect secondary production. In addition, this paper also ...

本文综述了国外在底栖动物次级生产力研究中的理论和方法，重点阐述了底栖动物次级生产力的计算方法、P/B系数、生产量以及影响次级生产力的因素，并总结了目前该领域的一些新进展，以期为国内相关研究提供参考和借鉴。

Methods and Results— We investigated the expression of PDE1 in explanted lungs from idiopathic PAH patients and animal models of PAH and undertook therapeutic intervention studies in the animal models.

方法与结果—我们研究了来自原发性PAH病人和PAH动物模型分离的肺脏中PDE1的表达情况，并且在动物模型中进行了治疗性干预研究。

Methods and Results— We inestigated the expression of PDE1 in explanted lungs from idiopathic PAH patients and animal models of PAH and undertook therapeutic interention studies in the animal models.

方法与结果—我们研究了来自原发性PAH病人和PAH动物模型分离的肺脏中PDE1的表达情况，并且在动物模型中进行了治疗性干预研究。

In traditional behaviour study the lack of effective measurement and analysis led to time taking, recorder disturbing, misplaying and inferior quantification.

本研究强调医工结合，充分利用现代生物传感、电子、计算机多媒体等高技术，在声光电屏蔽与严格温湿度控制的实验室内，对动物运动行为进行长时间无干扰监测分析，整个记录和初步统计过程完全由计算机自动控制完成，克服了现有行为学研究方法对动物产生的&二次干扰应激反应&等缺点。

Subjects resuscitated at 8 to 10 minutes had comparable outcomes to those resuscitated at 10 to 12 minutes.

在8-10分钟时进行复苏的研究动物与在10-12分钟时进行复苏的研究动物具有比较结果。

Somatic cloning by nuclear transfer bypasses the gonads and therefore is a good model to study imprinting regulations.

克隆动物作为印记基因研究的实验动物模型，已获得许多有意义的研究结果。

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。
