About *** vibration knowledge

Said above is the same as did not say well, first of all, we will see each object as a system, the system will have amplitude-frequency characteristics, presenting a frequency other than the wave has the effect of inhibition, and this frequency is the system's intrinsic frequency, that is, the system and the intrinsic frequency of the same frequency of the wave did not inhibit the role of the system, when a variety of frequencies of the wave through the system, the system will be the same only on the intrinsic frequency and the intrinsic frequency of the frequency of the wave does not inhibit, and absorb the energy to make the system itself oscillate, and the oscillation frequency is its intrinsic frequency, thus forming *** vibration. Wave does not inhibit, and absorb the energy of the wave so that the system itself oscillates, and the frequency of oscillation is its intrinsic frequency, thus forming a *** vibration.
