旋转运动

Kanade [1] in 1992 proposed a factorization method which can effectively avoid noise interference, while not restricted to a particular motion model, such as pure translation or rotation .

Kanade[1]于1992年提出了一种Factorization的方法，可以有效地避免噪声的干扰，同时不会受限于特定的运动模型，例如单纯的平移或是旋转。

Background— Primary ciliary dyskinesia is a recessie genetic disorder that is characterized by sinopulmonary disease and reflects abnormal ciliary structure and function. Situs inersus totalis occurs in 50% of PCD patients (Kartagener's syndrome in PCD), and there are a few reports of PCD with heterotaxy, such as cardioascular anomalies.

背景 先天性纤毛运动异常症是以呼吸道感染和纤毛结构与功能不正常为特征的隐性遗传性疾病。50% PCD患者易发生完全性内脏异位(如PCD中的Kartagener综合征)，有小部分PCD伴有心脏旋转不良等心血管异常现象。

In the system, a 2D motion model is established on the image plane of the static camera to predict the position of the object by Kalman filter, then by using homography relation, the predicted position of object can be obtained on the image plane of the dynamic camera.

为了保证微小型电机的速度和承载能力，同时获得较高的运转分辨率，提出一种以压电叠堆为驱动元件基于尺蠖运动原理的新型精密旋转电机方案。电机结构中转子无绕线结构，定子采用柔性铰链双侧对钳方式交替对转子起到钳位作用。

Afterwards, we propose a new constant coefficients measurement method in dynamic equation of robot manipulators, this measurement method includes three groups of experiments: group one, let each joint of robot manipulator keep static to measure the constant coefficients in gravity term of dynamic equation and Coulomb frictional torque, group two: let only one joint of robot manipulator move at a constant velocity to measure the viscous frictional coefficient and constant coefficients in effective inertia of dynamic equation, group three: let only one joint of robot manipulator move at constant acceleration at a time to measure constant coefficients in Coriolis and centrifugal term and coupling inertia of dynamic equation.

让操作器单个关节恒速运动，在对驱动系统中传动机构，减速装置和电感系数综合考虑的基础上，这组实验对粘滞摩擦系数及有效惯量中常数系数进行测量。这种测量方法只要求旋转关节的驱动电机施加恒定电压，回转关节驱动电机施加正弦波电压。3。让操作器单个关节恒加速运动，这组实验测量动力学方程中哥氏力、离心力项和耦合惯量项中的常数系数，这种测量方法只要求单个关节匀加速运动，而其它各关节保持静止，这种测量方法虽然要求关节匀加速运动，但不必进行关节角加速度检测，而只需进行关节角位移和角速度检测即可，输入量直接给定为输入电压。

I am AWARE that participation in Inline Skating, Skateboarding, BMX Freestyle, and all other camp activities involves motion, rotation, and height in a unique environment and as such carries with it the risk of injury.

我们当然不能使地球停止运动，但是我们可旋转干涉仪。

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
