旋转着的

An elliptic rotating field is produced when an induction motor operates in asymmetry, this paper proposes a model of jointed motion to describe the motion of an elliptic rotating vector and states that the elliptic rotating vector is jointed with two components, the main one rotates forward at a uniform speed while the adjunctive one jointed at the topend of the main one rotates backward around the joint point at a double speed, both make the elliptic rotating vector rotate at swinging amplitude, speed and direction.

感应电机不对称运转时产生椭圆旋转磁场，本文建立了描述椭圆旋转矢量的接合运动模式，说明椭圆旋转矢量是由一个主矢量带动一个付矢量一起旋转构成的接合矢量，主矢量以匀速旋转，付矢量链接在主矢量顶端同时绕着链接点相对主矢量以二倍速反向旋转，两者共同构成的一个单向椭圆旋转矢量。

As it orbits the sun,Uranus also rotates on its own axis,an imaginary line through its center.

在它绕着太阳的当儿，天王星也对着自己的轴心，一个通过其中心的假想线，旋转着。

The asphaltic sections form curving slices of materials within movement of the pathways emerging from the Velodrome Stadium.

沥青材料的赛道，弯弯曲曲，旋转着汇集到室内自行车场，而整个室内自行车场就像旋转起来的车轮。

I looked up to and saw what seemed to be a tiny bird wheeling and sailing.

我也抬头望去，只见一个象小鸟样的东西在旋转着，飘荡着。

He circled around and around in the water like a wheel, craning his neck out into the air after them.

他在水上像一个车轮似地不停地旋转着，同时，把自己的颈项高高地向他们伸着，发出一种响亮的怪叫声，连他自己也吓着了。

He circled around and around in the water like a wheel,craning his neck out into the air after them. Then he uttered the shriek so piercing and so strange that he was quite frightened by himself.

他在水上像一个车轮似地不停地旋转着，同时，把自己的颈项高高地向他们伸着，发出一种响亮的怪叫声，连他自己也吓着了。

She cried, pirouetting for his benefit and tossing her head so that the plume danced.

她边嚷边旋转着让他看最美的姿势，同时晃着脑袋叫那些羽毛跳个不停。

One, with a fan and some bits of paper, performed the graceful trick of the butterflies and the flowers; another traced in the air, with the odorous smoke of his pipe, a series of blue words, which composed a compliment to the audience; while a third juggled with some lighted candles, which he extinguished successively as they passed his lips, and relit again without interrupting for an instant his juggling.

还有一个耍弹簧地陀螺的演员，他使那些地陀螺滴溜溜转起来配合得极其巧妙，看了简直叫人难以置信，这些嗡嗡作响的陀螺在他的操纵下，活象是一些旋转不停的有生命的小动物，它们能在烟斗杆上，军刀刀口上，以及在那些拉在舞台上的头发一样细的钢丝上旋转着跑个不停，它们能围着几个大水晶瓶打圈转，它们能爬竹梯，能四面八方到处跑，同时发出各种不同的响声。

I want to go dancing and wear a dress that swirls and floats around me, and laugh.

我想跳舞，穿着环绕着我旋转飘动的衣服，欢笑着。

The real tangential velocity fluctuation indicated that there existed an instability of swirling flow in the cyclone.This instability resulted in the rotation center of the swirling flow deviating from the geometric center of the cyclone,which produced the quasi-periodic oscillation of swirling flow and gave the real tangential velocity fluctuation.

瞬时切向速度的变化反映了旋风分离器内旋转流的不稳定性，这种不稳定性导致了旋风分离器内旋转流的旋转中心与几何中心不重合，旋转中心围绕着几何中心摆动，由此造成了瞬时切向速度随时间的类周期的波动变化。

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
