| Abstract: | Heat conduction equation of frequency domain is the research target.The analytical solution of Green's function of the model is obtained by mathematical techniques.Through the analysis of intrinsic properties of inverse model,a new way which can choose cut-off point automatically according to the error of signal is established to seek new ways of practical online inversion. |
