1. Long long ago, we knew the periodic motion of a planet.

2. An example is periodic motion, such as the precession of a particle with intrinsic spin and magnetic moment in a constant magnetic field.

3. Periodic motion is motion in which the position(s) of the system are expressible as periodic functions,(/periodic motion.html) all with the same period.

4. The periodic motion is considered for an impact oscillator with damping.

5. Be this kind of relation and its motion, brought about the periodic motion of real economy.

6. The simulated extraction of weak frequency variation signal is carried out with the expressed Resonant frequency locking property when system transits from chaotic to great periodic motion.

7. Speed - gradient adaptive control method is used to direct chaotic motion to a periodic motion.

8. The instability of the unbalanced system motion may result in doubling period bifurcation, almost periodic motion and chaotic motion.

9. The harmonic oscillator is an exceptionally important example of periodic motion.

10. The dangerous value of control parameter which leaded to surf-riding and the domain of periodic motion and surf-riding were given.
