方向

X and y are Cartesian coordinates representing the zonal and meridional directions, and u and v are the corresponding velocity components.

x 和 y 分别表示笛卡儿坐标系中的纬圈和经圈方向，而 u 和 v 分别是这两个方向上的速度分量。

Traditional cartography develops from two dimensional and static state to the multidimensional, dynamic, interaction and virtual reality.

地图学的研究方向也突破了二维静态的限制，向多维、动态、交互和虚拟的方向发展。

The Causal Relation Data Mining is a new direction in the Data Mining research field,and it is very useful in the application.The Difficulty of modeling blocks its development.

因果关系挖掘是数据挖掘领域一个新的研究方向，具有很大的实用意义，但理论建模的困难阻碍了它的发展。20世纪90年代，在因果建模研究成果的基础上，国外开始针对此方向进行研究，目前已得到了一些理论算法。

Seawater intrusion mechanism and its 3D numerical simulation are further explored and researched in this paper. On the basis of the classical theory of fluid mechanics, it built the ideal model of seawater intrusion, and attained the speed in flow field which gradually decreased along with the increasing distance of curvature center along the principal normal in the course of seawater intrusion.

以流体力学经典理论为基础，建立了海水入侵内陆的理想模型，得到在海水入侵内陆的过程中沿弯曲流线的主法线方向，流场中速度随着距曲率中心距离的增大而逐渐减小，根据流线上的速度分布，并可表示出流场中的流线方程，可确定一定条件下海水入侵内陆的速度和方向。

Now that the beam has been successfully tested in clockwise direction, Cern plans to send it counterclockwise.

现在，已试射成功，在顺时针方向。Cern原来计划在逆时针方向。

The direction of electric machinery is the two inverting contactor that outside passing, receives, in control unit control falls, direction of switch of 0 electric current, won't produce alternate with circumfluent.

电机的方向是通过外接的两个换向接触器，在控制单元的控制下，零电流切换方向，不会产生相间环流。

The directional changeover of electric machinery is the two inverting contactor that outside passing, receives, in control unit control falls, switch way leaves in 0 electric current, won't produce alternate with circumfluent.

电机的方向转换是通过外接的两个换向接触器，在控制单元的控制下，在零电流下切换方向，不会产生相间环流。

First start in clockwise direction then repeat in an anti clockwise direction.

首先按顺时针方向活动眼睛，然后逆时针方向活动。

The results of this study determined a mean clockwise rotation of 2.2 degrees in the left eye and a mean counterclockwise rotation of 2 degrees in the right.

这项研究的结果确定了，左眼发生了平均为2.2度的顺时针方向旋转，而右眼发生了平均为2度的逆时针方向旋转。

A clockwise rotation causes the critical mode to occur in the area of 550 rpm and the propulsion force against the direction of gravitation vector is created.

顺时针方向旋转的关键原因模式将发生在该地区的550转速和推进武力的方向引力矢量创建。

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。
