A SU(N) gauge field model is discussed in details in this paper. In the limit $α\longrightarrow 0$ or $α\longrightarrow \infty$, the gauge field model discussed in this paper will return to Yang-Mills gauge field model. This theory could be regarded as theoretical development of Yang-Mills gauge field theory.15 pages, No figure, the expansion paper of hep-ph/9802236High Energy Physics - Phenomenologytext
