旋转运动

Lawrence martyr , 10 august : the monthly recurrence known as the new moon with the old moon in her arms : the posited influence of celestial on human bodies : the appearance of a star 1st magnitude of exceeding brilliancy dominating by night and day a new luminous sun generated by the collision and amalgamation in incandescence of two nonluminous exsuns about the period of the birth of william shakespeare over delta in the recumbent neversetting constellation of cassiopeia and of a star 2nd magnitude of similar origin but lesser brilliancy which had appeared in and disappeared from the constellation of the corona septentrionalis about the period of the birth of leopold bloom and of other stars of presumably similar origin which had effectively or presumably appeared in and disappeared from the constellation of andromeda about the period of the birth of stephen dedalus , and in and from the constellation of auriga some years after the birth and death of rudolph bloom , junior , and in and from other constellations some years before or after the birth or death of other persons : the attendant phenomena of eclipses , solar and lunar , from immersion to emersion , abatement of wind , transit of shadow , taciturnity of winged creatures , emergence of nocturnal or crepuscular animals , persistence of infernal light , obscurity of terrestrial waters , pallor of human beings

The tendency to rotate is due to the moment of the force, which is equal to force magnitude multiplied by the perpendicular distance of the line of action to the center of resistance.

力矩导致旋转运动，它等于力的大小乘以牙齿阻抗中心到力的作用线的垂直距离。

Pivot joint A joint in which a bone rotates around another; ajoint permitting only rotating movement.

We found that the time coefficients of POTT 、POTTOT and POTPyOT in solution are the same (~0.6ns) due to Intersystem crossing.However, the decay ISC time coefficient is 2.0ns for POTPy. We propose that rotation of the single bond between adjacent thiophenes enhances the rate of ISC. The results of these compounds in PMMA films and theoretical calculations confirm this mechanism.

在动力学量测方面，POTT、POTTOT及POTPyOT在溶液的结果是相似的，系统间转换过程的衰减时间常数都是~ 0.6 ns，然而在POTPy溶液中~ 2.0 ns，我们推测噻吩与噻吩之间单键的旋转运动加速了系统间转换的过程，而这个假设将由PMMA薄膜及理论计算的结果来加以证实。

In this paper,pose representation by quaternions are researched.With the basic quaternion algebra,the "quaternion based rotations combination theorem" is introduced and proved theoretically.On the basis of this theorem,a method for compute of pose nonliear state transfer function and its linearization is purposed.Then,the computing of the measurement function and the linearization is studied.With the Extended Kalman Filter,the pose is tracked and estimated.

研究用四元数表示物体的姿态，在四元数基本运算法则基础上提出并证明了"基于四元数的多个旋转运动合成规则"，然后将此规则为依据，推导出一种用来计算姿态非线性状态方程系数的方法，对非线性状态转移函数进行线性化，并且研究了测量方程函数的确定及线性化，借助扩展Kalman滤波实现了对姿态的跟踪。
