Abstract:
The impedence of tree cell is measured within its frgueney domain.It shows that fm(the freguency when the imaginary part of impedence is the maximum) located by analysing the impedence circle graph goes descendingly following the tree cell activity becomes ascending.This conclusion furnishes a theoritical foundation for measuring tree cell activity by impedence and makes the measurement greatly simplified.
Key words: Tree cell activity, Frequency, Impedence circle grdph
