转动方向

You should turn the key clockwise to open the door.

你应该按顺时针方向转动钥匙来开门。

You have to turn it clockwise.

你必须顺时针方向转动它。

A:hold the handle of the turning wheel with two hands,turn the wheel in the clockwise or counterclockwise direction at the same time.

使用方法：双手握紧转轮手柄，同时向顺时针或逆时针方向转动。该器械适合于年轻人。

Turning or spiraling from right to left; counterclockwise.

从右到左的，逆时针的从右向左转动或旋转的；逆时针方向的

The effects of cylindrical lens shape and the laser-fiber distance on relative coupling efficiency are also studied.

给出了一个计算980 nm泵浦激光二极管与柱形透镜光纤耦合角向容忍度的理论模型，并选择圆形的柱透镜光纤进行数值计算，得出了在水平和垂直方向上偏转加平移时的相对耦合效率及绕光纤轴向转动的相对耦合效率的数值计算结果并加以分析，同时也研究了光纤透镜的形状和激光二极管与光纤的间距对相对耦合效率的影响。

In this paper, the modeling theory of multi-rigid-body dynamics was thoroughly investigated in order to make up the shortcoming in the above modeling method. The major research achievements are as follows:①Based on the matrix of direction cosine between the body-fixed base and the reference base, and Poisson equation of a rigid body rotating, the coordinate transformation method for the modeling of treelike multi-rigid-body dynamics is derived. The method is very routinization and easy to use the computer to carry on the symbol derivation.

本文针对上述建模方法存在的不足，深入地研究了多刚体系统动力学的建模方法，并将所研究的新方法应用于惯性振动设备的建模，取得的主要研究成果如下：①基于刚体连体基关于参考基的方向余弦矩阵和刚体转动的Poisson方程，导出了建立树形多刚体系统动力学方程的坐标变换法，其过程极其程式化，便于利用计算机进行符号推导。

But just over the next range of hills, out of sight,to the north east, is a windmill that still merrily go es, and about five miles away to the north west is another also active; so that things are not quite so bad hereabouts as in many parts of the country, where t he good breezes blow altogether in vain

其中有一个已经破损得非常厉害，还有一个也只剩下了两个翅膀。但就在下一道山冈、远得望不见的东北方向，就有一座风车在那里欢快地转动着，另外由此再折向西北四五英里的地方，也有一个风车非常活跃。所以这个地方的情形还不至于像全国其他地方那么糟糕，任由阵阵好风从身边白白吹过

First of all, we should be familiar with the mechanical mouse click it works: by moving the mouse to bring rubber ball, plastic ball and rolling friction in charge of the mouse with horizontal and vertical directions of the gate roller wheel, drive wheel rotation gate.

首先，我们应该熟悉一下机械鼠标的工作原理：通过移动鼠标，带动胶球，胶球滚动又磨擦鼠标内分管水平和垂直两个方向的栅轮滚轴，驱动栅轮转动。

Rectifier motor - so excited DC generator string for AC motor, and the fait accompli of such motors, due to alternating current in the magnetic field and the armature circuit, while turning, the moment the direction of Constant Couple remain unchanged, it is turning non-stop.

整流电动机--使串激直流发电机，作交流电动机用，即成此种电动机，因交流电在磁场与电枢电路中，同时转向，故力偶矩之方向恒保持不变，该机乃转动不停。

But least moment of inertia in transverse direction.

但最少转动惯量在横向方向。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
