BACKGROUND: Effective proliferation in vitro of neural stem cells and directional induction and differentiation of dopaminergic neurons play a key role in neural stem cell transplantation for treatment of degeneration of the nervous system and repair of injured nervous system.

背景：在神经干细胞移植治疗神经系统退行性变及修复神经系统功能损伤过程中，有效的神经干细胞体外增殖与多巴胺能神经元的定向诱导分化尤为关键。

BACKGROUND: Muscle-derived stem cells have some problems in purification, amplification and directional differentiation during in vitro culture. Basic fibroblast growth factor as a membrane of bioactive factor has been paid great attention, due to its biological activity.

背景：肌源性干细胞在体外培养过程中存在纯化、扩增、定向分化等难题，碱性成纤维细胞生长因子作为生物活性因子的一员，因其生物活性的多效性而备受关注。

Proteomics technology provides a powerful tool due to the large scale, systemical study of protein transformation and interaction, which can be used for exploring molecular mechanism of bone mesenchymal stem cells during directional differentiation.

蛋白质组学技术是大规模、系统性研究蛋白质变化及其相互作用的强有力工具，可以用于骨髓间充质干细胞定向分化的分子机制研究当中。

Directional selection in disease field is the most simple, economic, and effective method for improving cotton resistance. Both land cotton and long-staple cotton high sensitive to the fusarium disease could improve its resistance in few years by this method and the farming properties were nearly unchanged.

试验证明，在供试材料中，不论是陆地棉的高感品种还是长绒棉的高感品种，经过在重病田或病圃中定向加压筛选，都可在几年内使其抗病性得到迅速提高，并保持其农艺性状基本不变。

On the one hand,Magnetic Polymer Microsphere could covalent active materials—enzymes,cells and antibodies;on the other hand,they could show strong magnetic responsibility for their directional movement in the magnetic field.

一方面磁性聚合物微球可通过共价键来结合酶、细胞和抗体等生物活性物质；另一方面因其具有"在外界磁场存在下能定向运动"这一特殊性能，可对外加磁场表现出强烈的磁响应性，因此它被用作酶、细胞、药物等的载体，广泛地应用到生物医学、细胞学和生物工程等领域。

In order to increase directivity and efficiency ,the optimum culture medium components were made certain according to breeding methods.

为了提高筛选的定向性和效率，根据育种思路确定了最佳培养基的配方。

It is shown through computation that the orientative exploring capacity of the tool is greatly enhanced because of the existence of the drill collar.

First to unfold were the two 14-foot-wide drogue chutes,which criented the craft and continued slowing it.

首先要打开的是那两个 14 英尺宽的拖靶斜槽，这两个东西使飞机定向，并继续使之减速。

Additionally and/or alternatively, low level component e.g., client(s and/or application can also be given access to a dynamic partition data store to manipulate (e.g., add, delete and/or modify) redirection information e.g., via interface component

另外和/或可替换的，也准许低等级的组件(例如，客户端和/或应用程序)访问动态分区数据存储单元以操纵(例如，添加、删除和/或修改)重定向信息。

Remember to edit line 5 to where you'd like to redirect mobile users.

记得要编辑代码的第五行，将它修改成你要将移动用户重定向到的页面地址。

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。
