BACKGROUND: Tranditional Chinese medicine, which possesses anti-oxidation properties, can promote directional differentiation of mouse bone marrow mesenchymal stem cells into nerve cells.

摘要背景：大量文献报道具有抗氧化作用的传统中药单体能促进骨髓间充质干细胞向神经细胞定向分化，红景天苷作为红景天的有效成分，具有较强的抗氧化功效。

The effects of geomagnatic field parameters in directional drilling,selection of non magnet...

探讨了地磁场参数在定向钻井中的作用、无磁钻铤长度的选择、测量数据的比较等问题。

Want, on search market, before Gu Ge and Yahoo are held from beginning to end two, compare with the competition of Yahoo with Microsoft more intense, searching engine and directional advertisement field, because captured,Gu Ge scores a success is of Yahoo portion, yahoo just is Gu Ge forever enemy.

想想看，在搜索市场上，谷歌和雅虎始终占据前两位，与雅虎的竞争比与微软的更加激烈，在搜索引擎和定向广告领域，谷歌获得成功是因为夺取了雅虎的份额，雅虎才是谷歌永远的敌人。

The unique coupling transmission performance of the TTC-PCF shows its possible applications in the design and preparation of coupling strength continuously tunable fiber directional coupler and large mode field fiber lasers.

结合TTC-PCF展现的独特耦合传输性能，讨论了其在耦合强度连续可调光纤定向耦合器和大模场光纤激光器的设计与制备等方面的可能应用前景。

Perpendicular search engine is to pour pyramid model, be pair of trade news comb, rework and editor are arranged, it is the professional search engine that is aimed at certain industry, the fractionize that is search engine and outspread, it is right some kind of technical information in webpage library undertakes conformity, directional cent field is draw-out the user is returned with some kind of form again after the data that gives need undertakes handling.

垂直搜索引擎是倒金字塔型，是对行业信息的梳理、再加工与编辑整理，是针对某一个行业的专业搜索引擎，是搜索引擎的细分和延伸，是对网页库中的某类专门的信息进行一次整合，定向分字段抽取出需要的数据进行处理后再以某种形式返回给用户。

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。

Its thought is to change the model of the asynchronous motor through the coordinate, make it become direct current motor model, divided the electric current vector of the stator into according to the weight of two pieces of direct current with directional magnetic field of the rotor and controls, realize magnetism coherent and torque solve lotus root control , in the hope of the control result of the direct current reaching machine.

其思想就是将异步电动机的模型通过坐标变化，使之成直流电动机模型，将定子电流矢量分解为按转子磁场定向的两个直流分量并分别加以控制，从而实现磁通和转矩的解藕控制，以期达到直流电机的控制效果。

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。

However, we can use simple directional thinking.

但是，我们可以使用简单的定向思维。

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。
