  In this paper, we use a modified Abelian field strength tensor in
Georgi-Glashow model and obtain a new Julia-Zee dyon equations which
degenerated into the 't Hooft-Polyakov monopole equations when the profile
function J=0. Combining a three-step iterative shooting argument and a
fixed-point theorem approach, we establish the existence of the static solution
of the Julia-Zee dyon equations and discuss its qualitative properties. In
addition, we show that the total magnetic charge is a constant related to the
gauge coupling constant and the total electric charge depend continuously on
the profile functions.
