定向进行

Ception can enter the dorsal-most laminae I and II but not grow further ventrally. As for the waiting period and the correct projection of the NT- 3 (neurotrophin-3)sensitive Ia neurons and other neurons, it is possible that other guidance cues might make more contribution.

至于腹侧投射性的神经营养因子习（neurotrophin3，NT3）敏感性肌梭h类神经元和其它神经元轴突的等待期和定向投射，则更有可能是在其它类型的导向因子的共同参与下进行的［81

According to the principle of analytical subsequent relative orientation, the formula of vertical parallax on corresponding point is deduced when stereo model is reconstructed by using the elements of exterior orientation of images. The method is verified by simulative images and tested by two kinds of different scale images taken from Xinjiang and Qianxi, China.

从连续法相对定向原理出发，推导了直接由像片外方位元素恢复立体模型时模型点上下视差的计算公式，用模拟数据验证了计算方法的正确性，并对两组不同摄影比例尺的实际航摄像片进行了试验。

Firstly, the object's position and orientation are determined by a vision system, the orientation of an object is the angle between the X-axis of the coordinate system and the axis of the least moment of inertia of the object in this system, and the position value is the vector between the coordinate zero point and the object's centre of gravity.

第一步利用视觉转动惯量法对任意放置在CMM工作台上的工件状态进行定位和定向；第二步利用测量离散点和模型投影点之间的关系，求取工件坐标系和设计坐标系之间准确的转换关系。

一方面促进有关班级环境、成就目标定向与学业求助行为研究的理论建设与发展，丰富教育心理学和学习心理学的内容，另一方面为促进适应性学业求助行为提供理论基础，特别是对实际上最需要帮助的学生进行有效的干预，提供理论参考。

Besides, the key biosynthetic genes were cloned and then expressed for directional breeding in molecular level .

同时，对福提霉素生物合成的关键基因进行克隆和表达，尝试在分子水平上的定向育种。

The technology problems of blasthole depth,cutting blasting,smooth wall blasting,and directional blasting is discussed.

文章对炮眼深度、掏槽爆破、光面爆破、定向爆破等技术问题进行了探讨。

To investigate feasibility and effect of schizophrenia treatment by stereotactic lesioning, CRW stereotactic apparatus and PICKER spiral CT were used to define nucleus location and RADONICS radiofrequency instruments were used to lesion different subnucleuses of amygdala and the front part of callosal gyrus.

采用CRW立体定向仪和PICKER螺旋CT定位，用RADONICS毁损仪毁损杏仁核不同亚核团和扣带回前部治疗精神分裂症 3 5例，并进行了一年的随访。

Methods CRW stereo tactic apparatus and CT were used to define nucleus location and Radonics radiofrequeney instruments were used to lesion different subneucleus of amygdale and the front part of callosal gyrus. All schizophrenic patients were diagnosed by CCMD-3 standards.

方法对32例难治性精神分裂症患者，采用CRW立体定向仪和CT定位，用Radonics毁损仪毁损杏仁核不同亚核团和扣带回前部，采用临床疗效总评量表、简明精神病量表和阳性与阴性症状量表和韦氏智力量表等评定疗效，并进行1年的随访。

The bone resection was divided into four steps via FLA:① drilling of the jugular tuberculum;② partial mastoidectomy;③ removal of the occipital condyle;④resection of the lateral mass of C1 with mobilization of the vertebral artery. After each step of the bone resection was completed, the exposed area of the central clival depression and the area of exposure 15 cm above the central point were calculated.

利用CT和立体定向仪对20例甲醛溶液固定的头颅标本标记斜坡中央凹陷区中心点，采用FLA入路，骨切除分四步进行：磨除颈静脉结节，部分乳突切除，枕髁全切，C1侧块切除；分别于每一步骨切除及血管神经牵拉完成后测量斜坡中央凹陷区的显露范围和位于中心点上方15 cm处术者的操作范围。

Methods Central point at the central clival depression was marked with the help of CT and stereotactic apparatus in 20 formalin-fixed cadaveric heads. The bone resection was divided into four steps via FLA:① drilling of the jugular tuberculum;② partial mastoidectomy;③ removal of the occipital condyle;④resection of the lateral mass of C1 with mobilization of the vertebral artery. After each step of the bone resection was completed, the exposed area of the central clival depression and the area of exposure 15 cm above the central point were calculated.

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。
