摘要
介绍两种求解高自由度体系微振动本征模式的方法．第一种方法：利用对称性经过物理分析寻找本征模式；第二种方法：利用对称性降低体系的自由度，然后用求解本征模式的一般方法解之．
Two solutions to normal modes of small oscillation for a system with high degrees of freedom are given.In the first place normal modes are obtained by using symmetry and physical analysis.The second method in that degrees of freedom are reduced by using symmetry,and then normal modes are solved by using the theory of small oscillations of a system.
