方向

Let it be constant rule to scrub the boards the right way; that is lengthways.

地板永远要朝适当的方向去擦，也就是要顺着的方向去擦。

Reform process as follows:(1)The reformation of machine part, include to enter lengthways to the reformation of the direction with horizontal enter to direction of reformation.

Based on the analysis of the geological tectonics setting and deep seated geophysical characteristics, the causative structure of the Yongdeng M S 5.8 earthquake on July 22, 1995 has been determined by the synthetical study of the faults in the earthquake area, focal mechanism solution, focal depths, meizoseismal region direction, post earthquake distribution, earthquake fissures and ground motion direction.

在分析地质构造背景和深部地球物理特征的基础上，通过对震区断裂构造、震源机制解、震源深度、极震区展布方向、余震空间分布、地震裂缝和地面运动方向的综合研究，确定了1995年7月22日永登5.8级地震的发震构造，探讨了形成该次地震的构造力学机制问题，认为该次地震是在局部构造应力直接作用下导致窑街—周家台隐伏断裂重新活动的结果

According to the field investigations,the characteristics can be included as follows:The meizoseismal region with an intensity of XI,showing obviously zonal distribution,suffers serious destruction from the earthquake,and the destruction perpendicular to the rupture decreases sharply.

地震现场考察认为：极震区烈度为Ⅺ度，表现为强烈的带状分布，且破坏很重，地震破坏在垂直于断裂的方向上衰减非常快；Ⅹ度区和Ⅸ度区垂直于断裂的方向上极窄，Ⅹ度区和Ⅸ度区偏小；烈度在断层两侧迅速衰减，但Ⅵ度、Ⅶ度区的影响范围非常大，Ⅵ度区的影响范围约24万km2。

The Cretaceous sedimentary rocks were baked by the basaltic lava flow erupted in the Early Miocene, contracting in volume owing to loss of water contained mainly in the clays of the clastic rocks, and thus forming the columnar jointing. According to the occurrences of jointing and the sedimentary strata the authors calculated the two different rotations of the Mellit block: the block tilted toward 338° for 18° from Late Cretaceous to the beginning of Miocene, and tilted toward 138° for 18° since Miocene.

可以合理地假定柱状节理在形成时是垂直于大地基准面的，根据柱状节理和沉积岩层的产状，笔者计算出Mellit地块的两期旋转事件：自晚白垩世初期到中新世初期该地块向338°方向倾斜了18°，而自中新世以来又向138°方向倾斜了18°。

By analyzing in detail the structural evolutionary history, from Mesozoic to Cenozoic, of different rift belts in western, northern, central and eastern Africa, the authors think that the Mellit area was on the northwestern shoulder of the South Sudan Rift. The rotation of the Mellit block toward northwest was the outward rotation of the northwestern shoulder of the South Sudan Rift during the rifting phase, and the rotation toward southeast was the inward rotation of the rift shoulder during the post-rift thermal sag episode.

经过详细分析非洲大陆西部、北部、中部和东部中新生代裂谷带的构造演化史后发现：Mellit地块实际上位于南苏丹裂谷带的西北裂谷肩上，该地块自晚白垩世初期至中新世初期，向NW方向倾斜是南苏丹裂谷带于裂谷化阶段造成的裂谷肩块体的向外旋转；该地块自中新世以来向SE方向倾斜是南苏丹裂谷带在后裂谷热沉降阶段造成的裂谷肩块体的向内旋转。

Upper central incisors moved forward and downward together with maxillary, at the same time they upright in the sagittal plane and tip mesially. 3 The occlusion plane rotated clockwise for about 1.5°. 4 The width increasement effect of RME comes from approximately the equal amounts of skeletal and dental expansion. The mode of dental movement was a combination of body and tipping movements of posterior teeth.

结果：1后牙在宽度方向上为整体移动和倾斜移动相结合的移动方式，但第一磨牙和第一双尖牙稍有差别；牙齿和骨对宽度增加的贡献各占约1/2；2后牙在垂直方向有伸长的趋势；3第一磨牙和第一双尖牙均向前整体移动，轴倾度保持不变；4中切牙整体随上颌骨前部向前向下移动，其牙长轴发生直立，轴倾度增加；5上颌平面发生顺时针旋转。

MB1 root canals of the mesiobuccal root canals in maxillary molars were found obvious curve out by the rate of 82.5% in mesiodistal direction,77.5% in buccoling

上颌第一恒磨牙四个根管在近远中方向、颊舌方向均有不同程度的弯曲，其第二弯曲出现的情况也各不相同。

本研究通过对80例离体上颌第一磨牙行近远中方向，颊舌方向x 线投照，旨在近一步了结其根管的弯曲走向，弯曲程度，弯曲位置。X线片只能反应根管在一个平面上的走向、形态。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
