Abstract:
The response charac teristics o f a diffusing particle w ith non-Ohm ic spectrum under a harm onic potentia l are investigated, and it is found that the system takes m ore tim e to atta in a ba lance for subd iffusion, and less time fo r superd iffus ion. Particular ly, a system of superdiffusion is m ore sens itive to the changes o f d ifferent param eters, wh ile for a subdiffusion system it ism ore obtuse. Them e thod used in th is paper is usefu l for the study o f character istics of the d iffusing particles under o ther exte rnal conditions
