[Transient response in electric measurement of human auricular point].
This is an experiment on the measuring E-t and R-t for human auricular point, which shows there is a transient response of electric potential E(t) and voltage drop U(t) when t < 2 tau and there is at intervals change with the time after 2 tau about R(t) and E(t). We have obtained a response function of the E(t) and U(t) by the circuit analysis. The parameter of the transient character is relaxation time tau,tau approximately RC. The mathematical model is in correspondence with the experimental result of the auricular point and TPM simulation. It indicates that the character changing with the time should be extracted after 2 tau. This experiment is of importance to understanding the electric character of the otopoint.
