摘要：
The proper orthogonal modes (POM) and normal modes of continuous vibration systems were discussed. The POMs in certain nonlinear structures resembled the normal modes of the linearized systems. It was found that the POMs approximate the discretized linear normal modes for free multi-modal motions of distributed systems.
