Abstract：
While deriving the effective potential by calculating the elastic scattering amplitude between quark antiquark,one would encounter the ordering problem. Even the hermiticity requirement is considered,various ordering schemes may still lead to different numerical results. We investigate this issue and present the preliminary results,then make some discussions.
