Abstract
The change characteristics of permittivity following the frequency of alternation electric field was surveyed by investigating Yam tissue.The results showed that the permittivity of the same thickness potato tissue was whole minishing by 1 V work tension.Permittivity increased with the increase of the thickness at the same frequency.Three minimal value of permittivity at the same thickness of Yam tissue came forth.The frequency with each minimal value of permittivity was constant correspondence with the increase of the thickness.
