Abstract：
We propose a new quantization scheme with which and by the equation of motion the quantization problem of both independent and dependent interacting fields in QED can be solved simultaneously. When the external gauge field A_μ^ex)≠0 (i.e., the Fermion field ψ/(x) and the electromagnetic field A_μ(x) are independent of each other) our scheme gives the same result as the usual quantization approach. When the external gauge field is absent the usual quantization conditions fail since it is not compatible with equation of motion, meanwhile our scheme is still valid. These results are demonstrated with solvable QED in 1+1 dimension.
