Abstract：
The winding number is calculated from the instanton solution under differentgauge conditions. It is observed that, though the boundary condition is definite, thevalue of the winding number still depends on the way of approaching infinity. InLandau gauge, it leads to winding number of half integral value by the limiting waywith clear Physical meaning. Particularly in temporal gauge and the result is irre-levant with the limiting way.
