请教一个定义

刚开始使用ADAMS,在振动的后处理中,对“Modal Participation Factors”的概念不是很明确,也没查到,希望哪位高手指教一下

Copy from "The Fundamentals of Modal Testing"
The weighting, often called the modal participation factor, is a function of excitation and mode shape coefficients at the input and output degrees of freedom.
The participation factor identifies the amount each mode contributes to the total response at a particular point.
