FREQUENCY RESPONSE CHARACTERISTIC OF NONLINEAR POLYNOMIAL SYSTEM
多项式非线性系统的频率响应特性

For nonlinear polynomial system,the analytical formula of the Multi-dimensionalFrequency Response Function(MFRF)are derived and the pole frequeney set is defined inthis paper.For applications in engineering,the extented transfer functionsin one-frequencydomain are defined basing on the investigation on the response frequency spectral structures.
