得到了一个模态是简单的固定自由弹簧-质量系统的本征模态的充要条件,以及两个给定的模态是同一系统的本征模态的充要条件。结果表明,当两个给定的模式满足这些条件时,它是可能的系统,这是唯一的,除了一个比例因子。
Necessary and sufficient conditions are obtained for one mode to be an eigenmode of a simple fixed-free spring-mass system, and for two given modes to be eigenmodes of the same system. It is shown that when two given modes satisfy these conditions it is possible to construct the system, which is unique except for a scale factor.
