Using the similarity between polynomialring and integer ring the paper establishes Sunse's Theorem in the polynomialring in number field, and offers its brief learning and practice.

In the case of(Char(F_q), |G|)=1, we provide a method that writing down directly all the primitive idempotents of related polynomialring, and hence that of all the minimum cyclic codes.
