动物研究

Based on the analysis on brachiopod fossils of the late middle Permian, the brachiopod extinction in The Lopingian event of late middle Permian in this area can he divided into two sub screens: the first screen in the end of earlier Wushisanti Subage and the second screen in the end of later Daozuanyan Subage. The second screen's extinct scope is larger than the first screen's.

通过川渝地区中二叠世晚期的腕足动物化石资料的研究，表明本地区中二叠世晚期的乐平世事件中腕足动物的灭绝可划分为前后2个不同的次级幕：早期的五十三梯亚期之末的第一幕和晚期的倒钻岩亚期之末的第二幕，且第二幕的灭绝规模要比第一幕更大。

Species in the mammalian order of Carnivora rank top in the animal food chain.

Its scientific programme is based on the study, analysis and interpretation of taxonomy, chorology, ecology, ethology, animal physiology, parasitology and the problems of zoonosis.

If you study the animal life,you'll find the main use of coloring is to protect themselves.

如果你研究过动物的生活，你会发现动物的主色彩是用于保护他们的。

Part of the findings shows the composition of pythoncidere is similar to that of the steam-distilled Cryptomeria japonica essential oil, based upon which an experiment about the Cryptomeria japonica essential oil's effect on animals is conducted. This leads to a further finding that the major element of terpene "limonene"is quite effective to central nervous system, and it can be hypnotic, anxiolytic and analgesic.

该研究还发现芬多精的组成与利用水蒸气蒸馏的柳杉精油的成分相类似，於是进一步以柳杉精油进行动物试验，发现了柳杉中的芬多精及其主要的萜类成分－「柠檬烯」，对动物中枢神经系统有相当大的影响，而且具有安眠、抗焦虑及镇痛的功效。

The site provides the information about IRGO and Ostracoda,museum collections and pictures of Ostracoda,research groups and individual research activities,international symposia and its proceedings,newsletters,Cypris,the list of microslide suppliers and journal titles.

该网站提供了有关IRGO和介形类动物的介绍、有关介形类动物管藏和图片、研究组和个人的研究活动、国际座谈会和会议录、有关介虫的活动通讯《Cypris》、论坛、显微镜玻片提供者名单、期刊列表。

In summary, that results suggested that the cytoplast of rabbit, bovine or goat oocyte can support reprogramming of nuclei of goat somatic cells and early development in vitro of reconstructed embryos, a

这些研究结果，不仅对完善动物克隆技术，而且对促进动物繁殖学、发育生物学的发展均具有重要的科学意义。

The three types of reconstructed embryos(reconstructed embryo of goat-rabbit, goat-bovine and goat-goat) were produced respectively by nuclear transfer using goat ear firbroblast cells as donors and rabbit, bovine and goat ooctyes as recipients, and the factors of cytoplast environments influencing cloned embryo development in vitro, cytoplast effect in nuclear transfer, the methods of transferring cloned embryo and the effects of pregnancy factor on implantation of cloned embryo were studied in this experiment, in order to supply basis for solving the difficulty of implantation of inter-species cloned embryo in recipient and improving the efficiency of cloning.

本试验以波尔山羊耳成纤维细胞为供体，分别以牛、羊、兔的卵母细胞为受体进行体细胞核移植，构建了山羊-兔、山羊-牛和山羊-山羊三种重构胚。研究了不同的胞质环境对重构胚体外发育的影响与核移植中的胞质效应，并对异种克隆胚胎采用了去透明带移植和配种后再移植的方法，探讨移植方法和妊娠因子对异种克隆胚胎在受体动物体内发育的影响，旨在为解决异种克隆胚移植不易着床发育的难题和为提高动物克隆效率提供理论依据。

The captive breeding project of the Darjeeling zoo is aided by scientific research and effective monitoring of the animals.

这种大吉岭动物园里的培育计画，有科学研究和有效的动物监控帮忙。

To study the applicable prospect of suicide gene on tumor therapy in clinic,we cloned the gene of D-amino acid oxidase and the gene of yeast cytosine deaminase.We hope to establish the transgenic mices of DAAO gene and YCD gene,and the two transgenic strain mices are valuable animal system for studying the biological characteristic of DAAO gene and YCD gene ,for studing the killing activity of DAAO/D-Ala and YCD/5-FC gene therapy systems on tumor.The D-amino acid oxidase gene derived from R.gracilis and it could oxidize D-amino acids. Hydrogen peroxide(H2O2) is a reactive oxygen species generated in the deamination of D-Ala catalyzed by DAAO.

为了探讨自杀基因在临床肿瘤治疗中的应用前景，建立自杀基因肿瘤治疗评价的动物模型，我们克隆了D-氨基酸氧化酶(D-amino acid oxidase，DAAO)基因和酵母菌胞嘧啶脱氨酶(yeast cytosine deaminase，YCD)基因，希望建立DAAO基因及YCD基因转基因小鼠，为研究DAAO及YCD基因的生物学特性、开发和评价DAAO／D-Ala及YCD／5-FC自杀基因系统进行肿瘤治疗建立良好的实验动物模型。

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。
