| Abstract: | The time series of BAEP are reconstructed by the technique of two-dimension tine delay.Grass berger Procaccica algorithm is used to calculate the correlation integrals C(r) of a normal person and apatient who has auditory hindrance.The results indicate correlation dimension D2 for a patient is higherthan that of a normal person in local hear liegion and their D2 can't converge.The numberical simulation of Mackey-Glass equation shows noise is not the essential reason affecting D2.Therefore,BAEPsignals can't be a stable chaotic attractor and D2 can't be taken as a criterion of clinical recognition. |
