旋转地

These asteroid-sized objects pack sunlike masses, extremely small orbits, and incredibly fast spins.

这些小行星有着太阳大小的质量，而且体积极小，它们在以难以置信的速度快速地旋转。

A circular potentiometer allows for smooth dimming and the lamp head can be swiveled within an angle of 90 degrees.

一个环形的分压器允许光滑地变暗还有灯头可以在90度旋转。

The soldier swiveled a little in his seat, annoyedly.

大兵懊恼地在他的位子上稍稍旋转一下身子。

Ken swiveled enough to get Jason into the line of fire as the Condor leaped backward with a fling of his arm, and Ken's saucer smacked into Jason's chest.

当秃鹰以他的手臂投掷向后地跳跃，而且肯恩的茶碟进入杰生的胸之内有味道的时候，肯恩足够旋转争取杰生进火线之内。

It is shown that even for the case of vanishing IMF strength the bow shock is not rotationally symmetric with respect to the Sun-Earth line: the east-west dimension of the cross section of the bow shock exceeds the north-south dimension by about 9~11% on the terminator plane (dawn-dusk meridian plane) and its sunward side, and becomes smaller than the north-south dimension by about 8% on the tailward side of the terminator plane.

模拟结果表明，即便对于IMF强度为零的情况，弓激波相对日地连线也不具备旋转对称性质：终端面及其向阳侧的弓激波截线的东西宽度大于南北宽度（约9%~11％），终端面尾侧的弓激波截线东西宽度小于南北宽度（约8％）。

Instead of revolving platforms or individual floors, the entire structure will turn once a week, a pace that Tav Singh, the project's manager, calls "dignified".

整座楼将一礼拜一圈地一起转而不是每层楼各自为政。而该项目的经理Tav Singh声称之所以要以此速旋转乃源于一种&高贵&。

We let the music we were only vaguely familiar with roar throu gh the house. And we twirled.

我们让似曾相熟的音乐在屋子里轰鸣，我们则在一边随着音乐飞快地旋转。

The speed-sensorless vector control and the identification of motor parameters in this paper are the two novel research of vector control.Using asynchronous machine's mathematic model in three-phase static reference frame, this paper has derived it's mathematic model in two-phase static reference frameand in two-phase rotating reference frame, and got the coordinate transformance formulus based on the constant magnetic force and power force, by compared different field orientation methods, we can find that field orientation at rotor field can realize the decoupling of the stator current flux component

无速度传感器矢量控制和电机参数辨识是矢量控制的两个新的研究方向，本文利用异步电机在三相静止坐标系下的数学模型推导出两相静止坐标系、两相同步旋转坐标系下的数学模型，根据磁动势守恒和功率守恒的原则，得出各坐标变换公式；通过不同磁场定向方式的比较发现，异步电机按转子磁场定向时定子电流励磁分量和转矩分量可以比较方便地实现解耦。

In this method the initial values of perspective projective matrix; rotative matrix and translative matrix are calculated from the fundamental matrix, than these matrices are optimized based on the coordinate value of corresponding points.

该方法从基本矩阵计算初始透视投影、旋转和竖直平移变换矩阵，然后以对应点坐标为基础对这些变换矩阵进行优化计算，从而有效地避免了优化计算的局部最小值，而且不过分依赖基本矩阵的计算精度。

The sun, as if it had feet, moves softly and lightly and I, uncomprehensively, start to turn about.

太阳他有脚啊，轻轻悄悄地挪移了；我也茫茫然跟著旋转。

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
