Inequalities between the eigenvalues of matrices andits real parts as well as its imaginary parts;

By calculating the relative integrals of the function and the residues of a meromorphic function and taking their real part,thus this paper got the analogous result with primitive Poisson-Jensen′s formula in form,then applied the analogous result to a practical example,it illustrated correctly.

A strict proof of the formulas of the convergence real part,absolutely convergence part and uniform convergence real part for the exponential series has been given.
