1、This result is known as the Bohr correspondence principle.
2、In this paper, the nonlinear mode correspondence principle in nonlinear vibration theory is proposed and proved.
3、In order to discuss this wave property, it is beneficial to use one form of correspondence principle.
4、According to the correspondence principle and FFT, the author have calculated the displacement field of a double-couple point source in homogeneous, isotropic, unbounded medium.
5、The correspondence between the nonlinear viscoelastic and the nonlinear elastic constitutive relations is found first, and then two elasticity recovery correspondence principles are deduced.
