| Abstract: | The problem concerning principal mode of a system with equal natural frequencies puzzles most juniors and up to the present. Almost all the books on vibration in China have not dealt with the problem theoretically in detail. This paper discusses the problem systematically and thoroughly in theory and proves a unified formula for the corresponding modes. |

| Keywords: | linear vibration principal mode rank/equal natural frequncy adjoint matrix |
