By deriving limiting zero point of the equation,some sufficient conditions that guarantee the existence and uniqueness of traveling wave solution of this equation are obtained.

Furthermore,it also discusses the application of theorem of zero point in our life,to achieve the goal of combining theory and practice in mathematical education.

Through some examples the author enumerates three kinds of problems testifying the existence of formula root and further proves it by using Zero-Point Theorem, Rolle Theorem , Lagrange Middle Theorem , reduction ad absurdum proof,etc.

This article extends the zero-point theorem for continuous functions from a closed interval to other types of intervals,and a series of zero-point theorems for continuous functions on relevant intervals are obtained,so that the theory on the zero-point theorem can be applied in more general cases.

In this paper ,the inferences and their proof about the property for continuous function of closed interval -Zero point theorem, Intermediate value theorem and the mean value theorem for derivatives-Rolle theorem ,Lagrange mean value theorem are given.

In this paper we summarize several kinds of identification methods of the Zero point theorem,and discusse the way of exploring the zero point of function.
