使弯曲

It isn't easy to bend an iron rod.

使铁棒弯曲并不容易。

Lorentz force is always perpendicular to and . It cannot change the particle's speed and can change only the direction of (and such the direction of travel).

始终与电荷的运动方向垂直，因此洛伦兹力不改变运动电荷速度的大小，只能改变电荷速度的方向，使路径发生弯曲。

Ask the patient to make a fist, extend and spread his fingers, flex his wrists, and extend them, and move his hands laterally and medially.

要求病人手握成拳，然后伸展手指，弯曲手腕，尽可能舒展开来，并使病人的手的侧面和中间部位活动

Therefore the disturbance of the phase velocity or meander amplitude could make the motion of the fluid particles chaotic.

弯曲急流的相速，振幅发生周期扰动均可使流体质点的运动出现混沌特性。

The PZT plates were polarized in thickness direction. By using the deformation in the plane perpendicular to the direction of polarization, the rotation around Z axis was generated when the torsional vibration around Z axis mode was excited. And the rotation around X axis or Y axis was generated by combining the longitudinal vibration mode and the bending vibtration mode.

利用压电陶瓷在垂直极化方向平面内的变形，激励定子绕Z轴的扭转振动模态，实现转子绕Z轴的转动；激励在定子中固有频率接近、振动方向相垂直的伸缩振动模态和弯曲振动模态，并通过振动的叠加使定子末端质点产生绕X轴或者Y轴的椭圆运动，实现转子绕水平轴的转动。

The gravitational field of the visible foreground galaxy breaks light from this distant quasar into four distinct images.

前景星系的巨大引力场使这颗遥远的类星体发出的星光被弯曲成四个不同的影像。

In the space of relative vacuum, the wave of gravitation of produce the connection of gravitation of at the mutuality of each quantum spatial measurement, in the crooked space of relative vacuum the mark of path also is crooked mark, make the mark of path quantum spatial measurement also come to do curve, cosmic energy not can leave the space of cosmic time-space.

在相对真空空间中，在各宇称量子之间产生引力关联的引力波，在相对真空的弯曲空间中的径迹也是曲线，使宇称量子的径迹也成曲线，宇宙能量逃逸不了宇宙时空空间。

The device of the shoe includes plastic prevent slippery hammer, it plays reed to be united in wedlock together with what compress steeliness to become, want slippery to preventing hammer to bring to bear on only any force, can make energy can be drawn again when playing reed to shrink to become it into football shoe; to bend, reduce the pressure that sufficient ministry place gets then.

鞋的装置包括一个塑料防滑钉，它与压缩钢制成的弹簧片结合在一起，只要对防滑钉施加任何力量，都会使弹簧片缩入足球鞋；而当它弯曲时又会吸收能量，进而减少足部所受的压力。

The main components of the lathe are the headstock and tailstock at the oppoaite ends of a bed,and a tool-post between them which holds the cutting tool.the tool-post stands on a cross-side which enblesit to move sidewards across the saddle or carriage as well as along it,depending on the kind of job it is doing.the ordinary centre lathe can accommodat only one tool at at time on tool-post,but a turret lathe is capable of holding five or more tools on the revolving tueeet.

刀架位于一个纵面板上，小拖板使刀架能够根据加工操作的不同作纵向移动；同时又随大拖板作横向移动。普通顶尖车床只能在刀架上夹持一件刃具，但六角车床可以在其旋转的六角刀架上夹持五件或更多的刃具。车床的床身必须很牢固结实以避免在受力的时候弯曲和变形。请提问的同学最好参观一下工厂的金属切削/机加工车间。那里有车床，还有其他种类的金属切削机床。

It utilises a unique two-piece aluminium design that makes replacing worn or bent parts very easy.

它采用独特的两件式铝设计，使更换磨损或弯曲件很容易的。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
