前后向的

The technical plan in the research on hand tractor attached driving disk plow is expounded with function analysis system technique.

本文从人－机－环境系统出发，综合分析了诸因素之间的内在联系，应用功能系统分析技术，阐述了手扶拖拉机配套驱动式圆盘犁研究过程中有关技术方案，分析了工作偏角α，机组侧向力的平衡、前后圆盘耕深一致等关键技术。

Some sit mutely, staring into space, lost in a world of their own; others cry out, rocking backwards and forwards.

一些孩子呆呆地坐在那里，空洞的眼神望向虚空，迷失在他们自己的世界里；还有些孩子在哭闹，不断前后摇晃。

A configuration that transition points are reflection symmetric about the midpoint with phase offset in one period is proposed. The intensity of the zero order becomes the function of the phases and can be eliminated.

采用周期内位相突变点镜向对称，前后半周期位相相差结构设计的反对称型达曼光栅，可使其零级衍射光斑强度仅是位相的函数，因此可消除零级谱点。

Methods A 3-D finite element model of the wrist based on CT scan images was established. The load transmission of carpus and the distribution of contact stress on radiocarpal joint under axial compressive force on metacarpals as well as the effect of transverse carpal ligament release on the displacement of carpal bones were computed and analyzed.

通过CT扫描图像数据对腕部进行三维有限元建模，计算并分析掌骨受轴向压力作用下正常腕部载荷传递及接触应力的分布，以及腕横韧带切开前后腕骨运动的变化情况。

In addition, it is well known that axial force coefficient denotes the pressure drop across the turbine to a great extent.

因此，如果知道了轴向力系数，就可由透平的运动状态获得透平前后的压降。

This technique applied in 46 cases of pneumonectomy , processing as cutting the anterior and posterior wall of bronchus into two bevels facing interiorly with a 45

对46例肺切除患者术中切割支气管时，使其前后壁形成两个向内的斜面，并与支气管纵轴成45°角，间断缝闭支气管残端。

Objective To explore the effects of engrafted neural stem cellson the recovery of structure and function in the spinal cord transected rats.

结果 移植的神经干细胞能在宿主内存活并向前后方向迁移到脊髓内，部分神经干细胞分化为GFAP、NF 2 0 0和GAP 4 3阳性细胞。

Also, the class with three hadrosaurs from jaw, can chew food and direction and lateral movement, accordion, like.

而且，鸭嘴龙类的颌骨以三个方向咀嚼食物，可以上下、前后和侧向运动，像手风琴一样。

Sierra Denali also offers a unique combination of interior style and luxury, including standard nuance leather-covered front and rear seats, with heated, 12-way power-adjustable front seats, as well as leather trim throughout.

塞拉利昂德纳里还提供内饰风格和豪华，包括标准细微皮革的独特结合，与加热，12向电动可调前排座椅覆盖前后座椅，以及整个皮革装饰。

Results The single half frame (HF1) was the worst, the delta frame was better, and the half ring frame was the best in over-all performances with regard to rigidity.

对改良AO外固定器进行了5种构型的刚度、屈服点测试，检测指标为抗轴向压力、扭转力、前后弯曲力和侧方弯曲力。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
