| Abstract: | In this paper, a parameter identification system of equations to determine the loss factor and the coupling loss factor, frequency band by frequency band, is given by treating a subsystem as an unit for conservatively coupled stru-ctures and non-conservatively coupled structures respectively. The results of experiments show that the method suggested the in this paper is desirably. |
