| Abstract: | Nonlinear directly estimating formula for exponential curve which,through fixed point,was derived,by using first order approximation of Taylor expansion.Examples showed that this method was better than classical method of linearization,which was comparable to nonlinear iterative estimating procedure. |

| Keywords: | exponential curve curve fitting correlation index |
