Though can not accurate induce neural stem cells specific orientation differentiation yet,to accompany the unceasing deepen recognize of convection mechanisms in cells' signal convection and discovery of new cell facter,new chemo-signal, Homo sapiens would solve the question of orientation differentiation from totipotential stem cell,multipotential stem cell to neural stem cell, orientation nerver ancestor cell then special tipe neural cell, implementation functional reconstruction betwen neural cell,for ultimate solve the proble of neural regeneration developing the way.

尽管目前尚不能准确有效的诱导神经干细胞特异性定向分化为某种特定的神经元，但随着人们对细胞间信号传递机制认识的不断加深和新的细胞因子、化学信号的不断发现，人类将能够解决从全能干细胞、多能干细胞到神经干细胞、定向神经祖细胞直至特异类型神经细胞的定向分化，完成神经元之间的功能重建，为最终解决中枢神经再生这一难题而开辟道路。

Extracellularly recording the responses of dLGN neurons to sinusoidal gratings with different orientations showed that optimum orientations of dLGN neurons in trained cats, compared with that in untrained cats, did not shift in favour of the trained orientation. For cells with receptive fields located within 15°visual acuity away from the foveae, there are no difference in orientation bias and firing rate at trained orientation between the trained cats and untrained cats.

细胞外记录外膝体背核神经元对不同方位正弦光栅刺激的反应显示，垂直或水平方位正弦光栅信号训练的猫，与正常猫相比，其外膝体细胞的最优方位并未向着训练方位发生明显改变，对于感受野位于中央区15 度视角以内的细胞来说，其方位选择性强度以及在训练方位的发放强度与正常猫无明显差异。

Orientation field near core point is changeable which is influenced by core point. Then fingerprint orientation field outspreads. At last, orientation field converges at delta point. This model can explain well why core and delta points exist in pairs in fingerprint images.

基线区域和中心点区域的指纹方向场向外扩张，在三角点区域汇合，且三角点是最终的汇合点，这一模型能比较好地解释指纹中心点和三角点成对出现的原因。

Orientation field near baseline is parallel to baseline which is caused by baseline. Orientation field near core point is changeable which is influenced by core point. Then fingerprint orientation field outspreads.

基线区域和中心点区域的指纹方向场向外扩张，在三角点区域汇合，且三角点是最终的汇合点，这一模型能比较好地解释指纹中心点和三角点成对出现的原因。

Through literature material and logic analysis,this paper reviews the evolution of the sports dance's value orientation,according to the study of dance and sports.It discusses the similarities and differences of the target,function and measure of sports dance between sports orientation and arts orientation.Based on the analysis,major problems are analyzed in the development of sports dance under the two value orientations in China.Meanwhile,suggestions and solutions are put forward in realizing dual value c...

文章采用文献资料、逻辑分析等方法，从舞蹈学、体育学的视角，回顾了体育舞蹈价值取向的历史演变，探讨了当前竞技取向与艺术取向下体育舞蹈的目标、功能和手段等方面的共性与异性；在此基础上分析了两种价值取向下我国体育舞蹈发展中出现的主要问题，并提出了双重价值整合的对策建议，以期为推动我国体育舞蹈发展提供有益的参考。

E. interpolation of ellipse center-of-gravity offsetting. The algorithm con process the received information of GPS dynamic orientation as quasi static information (genetic orientation information). Then the current information of the orientation can be calculated by using genetic and received pseudo-distance information.

这种插值算法将某个时段内由GPS接收机收到的动态定位信息进行处理，使这些信息变成准静态定位信息，用这些准静态定位信息和当前接收到的伪距动态定位信息计算出当前的实时定位信息。

The orientation-singularity expression of the Stewart platform is deduced by using unit quaternion which can avoid singularity when using Euler angles to represent the orientation of rigid body, and then the algorithm of orientation-workspace of the manipulator at a certain position is proposed.

基于单位四元数描述的刚体姿态，避免了欧拉角等描述刚体姿态的奇异性问题，推导出Stewart机构处于给定位置时的姿态奇异解析表达式，并提出了该机构处于给定位置时的姿态工作空间算法，通过计算机仿真给出该机构处于一给定位置时姿态奇异轨迹和姿态工作空间的三维可视化描述。

Test of simple tension at different orientation ; angle of orientation ; yield condition of aeolotropy ; plasticity strain ratio ; bidirectional fortification or weakening

不同取向的单向拉伸试验；取向角；各向异性屈服条件；塑性应变比；双向强化或双向弱化

The conventional aerotriangulation solves only the elements of exterior orientation 〓ω,κ, X〓, Y〓, Z〓 of photo, whereas the elements of interior orientation x〓, y〓, f of aerial camera are often determined in the laboratory. As the laboratory methods can not take into full account the actual conditions in aerophotography, large deviations often occur.

长期以来，航摄仪的内方位元素主要在实验室采用物理方法检定，而像片的外方位元素则主要依靠空中三角测量和大量地面控制点间接解求。

The American Psychological Association defines sexual orientation as such: Sexual orientation is an enduring emotional, romantic, sexual, or affectional attraction that a person feels toward another person.

美国心理协会是这样定义性取向的：性取向是对他人持久的情绪、情感、性和情感吸引上的状态。
