Restriction Conditions of Motion Equations of Non-Abelian Gauge Fields   and Their Wave Solutions
  Similar to introduce the Lorentz condition in the motion equation of electromagnetic field, the restriction condition is introduced in the motion equations of non-Ablian gauge fields so that the equations are simplified greatly and their wave solutions are obtained. Only in this way, the Feynman rule's use become rightful in the calculation of perturbation theory.
