resonance

释义

resonance

Suppose that a body capable of performing oscillations is subject to an applied force which is itself oscillatory and not subject to any resistive force. In certain circumstances the body may oscillate with an amplitude that, in theory, increases indefinitely. This happens when the applied force has the same frequency as a natural frequency of the body, and then resonance is said to occur. For example, if the equation $inline$ holds, there is resonance when $inline$ in which case the solution of the equation involves the particular integral

which gives oscillations of increasing amplitude.
