The increase of alkyl content can reduce the viscosity of the carbonization system, which is beneficial to the development of flow texture and uniaxial orientation.

针状焦形成过程中中间相沥青的烷基含量增加使体系黏度降低，有利于光学各向异性相的融并和定向排列。

The tail unit is formed by two vertical fins each placed on one of two tail booms and joined at the top with a horizontal stabiliser. The plane's fuselage is a separate module with attachment lugs for nose landing gear, wing and support pylons.

尾巴单位由二垂直的飞翅每个形成被安置在二尾巴景气的当中一个和被加入在上面与一个水平平衡器。plane's机体是一个分开的模块与附件把手为前起落架、翼和支持定向塔。

In this paper though built a mathematical model of single cell structure of wood fiber,oriented machining method for micro-wood fiber was analyzed and determined,and also the splitting crack condition to form micro-wood fiber was discussed as well.

Highlight the well-oriented investment, fixed investment, professional investment, with emphasis on business logisticscong tai organize, as well as to the Yangtze River Forum, the Pearl River Delta, such as a number of domestic investment activities, the formation of all-round, multi-level and wide-ranging pattern of opening up.

突出做好定向招商、定点招商、专业化招商工作，重点组织好丛台商贸物流高峰论坛以及赴长三角、珠三角等多项国内招商活动，形成全方位、多层次、宽领域的开放格局。

This research finds out that there are differences of students with different majors, grades and self-estimation in four dimensions of achievement goal orientation.

最近Elliot[5]和Pintrich[6]在逻辑推论和实证研究基础上，进一步将掌握目标划分成掌握趋近目标和掌握回避目标，这样就形成了四种目标定向的理论结构，这四种目标分别是掌握趋近目标、掌握回避目标、成绩趋近目标和成绩回避目标。

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。
