Abstract：

Let　G　be　a　graph　of　order　n　and　let　λ1,　λ2,...,λn　be　its　eigenvalues.　The　Estrada　index　[2]　of　G　is　defined　as,.　In　this　paper,　new　bounds　for　EE　are　established,　as　well　as　some　relations　between　EE　and　graph　energy　E.　©　2010　Editorial　Committee　of　Applied　Mathematics-A　Journal　of　Chinese　Universities　and　Springer-Verlag　Berlin　Heidelberg.
