| Abstract: | A new approach called perrurbation theory is presented to analyze the electri-cal impedance for medicine. The formula of constant voltage and constant current field per-turbation, modified G-L formula and the formula of electrical field perturbation evoked by sound field are derived. The applicafion resnlts of the theory in electroglottographic method are also introduced. |
