By choosing the proper parameter for each pulse, the dynamic phases induced by different pulses cancel out. The total pure geometric phase varies from-n to n, which realizes the arbitrary geometric rotation of spin. 通过对每个脉冲选取恰当的参数,由不同脉冲诱导的动力学相相互抵消,可得到由-π到π的纯几何相,于是实现了对自旋的任意几何转动。
Two sources of torsion are studied macroscopic rotation and aligned spin. 挠率的两个源被研究&宏观转动和排列自旋。
That rotation dictates the future spin of the sun and the orbit of its planets. 开始的旋转决定着恒星未来的旋转以及行星轨道的性质。
Forearm muscle speed and strength training can serve to improve the success rate of rotation and increase the spin of the ball. 前臂肌肉的速度力量的训练,能够提高旋转发球速度、成功率和增加球的旋转。
Determination of the ratio of the spin rotation coupling constant to the spin exchange constant for the k ~ ( 39 ) xe ~ ( 129 ) van der Waals molecule 范德瓦耳斯分子K~(39)Xe~(129)中的自旋-转动对自旋交换耦合常数之比的确定
