摘　　要：A new approach called field perturbation theory is presented to analyze the electricalimpedance technique for medicine.The formula of constant voltage and constant current fieldperturbation,modified G-L formula and the formula of electrical field perturbation evoked bysound field are derived.The application results of the theory in electroglottography are alsointroduced.A new approach called field perturbation theory is presented to analyze the electrical impedance technique for medicine.The formula of constant voltage and constant current field perturbation,modified G-L formula and the formula of electrical field perturbation evoked by sound field are derived.The application results of the theory in electroglottography are also introduced.
