确定了任意支承方式下欧拉梁横振动时其频谱和位移、转角、应变模态的一些重要特性，阐明了梁的位移模态的充分必要条件．
Some important qualitative properties of the frequency spectra and modes for Euler beams with arbitrary supports are determined. The case of supports free-pinned, free-sliding, free-free and sliding-slinding are considered, the rigid-body modes occur for beams with such supports. In addition, the sufficient and necessary conditions of a mode of the beams are obtained.
