The rabbits were immobilized according to the standard of X_knife before CT scanning. The interrelation of the silica gel tube and bony structures was analyzed, a nerve segment was selected, which could be localized according to the related bony structures as irradiation target. A radiosurgery treatment planning was performed on the selected nerve segment, its changes of pathology and ultrastructure were observed. Results: Base on the dissection, the rabbits' sciatic nerve was composed of the seventh lumbar nerve and first and second sacral nerves.

通过解剖分析兔坐骨神经主干的解剖位置和行径，选择照射靶点，放置硅胶管进行标记，按X_刀标准行CT扫描，从CT图像上分析硅胶管与荐骨和髂骨的位置关系，确定可以用骨性结构定位的神经段作为照射靶点，利用立体定向技术单次大剂量照射坐骨神经，观察其病理及超微结构变化。

Minsheng's Shanghai-listed shares have almost doubled this year, despite a massive block sale in March, and it is mulling a listing in Hong Kong.

尽管民生在3月份进行了大规模定向增发，该行在上海上市的A股今年还是上涨了近一倍。民生还在考虑赴香港上市。

In order to realize precise directionality, laser spot should be located precisely in sub-pixel.

为提高全向激光告警的定向精度，需要对激光光斑进行亚像素级的精确定位。

The isolated cells are able to orient and migrate to the magnet in artificial magnetic field but could not orient swimming only under the geomagnetic field. Magnetosomes produced by Acidithiobacillus ferrooxidans were range from 40nm to 90 nm according to the results of TEM. Energy dispersive X-ray analysis indicated that extracted magnetic particles consisted of oxygen and iron. The results show that some Acidithiobacillus ferrooxidans cells have weak magnetotaxis and they could be able to be separated by solid-plate magnetophoresis method from others. With the development of this new isolation method, it is possible that we could do deeper research to generate a comprehensive description of the mechanism that how Acidithiobacillus ferrooxidans synthesize the magnetic particles.

实验结果表明，氧化亚铁硫杆菌具有较弱的趋磁性，在人工磁场下会进行趋磁运动，但仅在地磁场作用下不能定向运动，利用固体平板磁泳筛选纯化含有磁性颗粒的氧化亚铁硫杆菌的方法是切实可行的，磁泳分离技术的进一步完善和改进为传统的微生物菌种分离提供了新的途径，为研究纯氧化亚铁硫杆菌菌株胞内磁性颗粒的形成条件及机理提供了前提条件，也为今后从浸矿细菌中分离筛选更多的含有磁性颗粒的菌株打下基础。

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。
