In the case of(Char(F_q), |G|)=1, we provide a method that writing down directly all the primitive idempotents of related polynomial ring, and hence that of all the minimum cyclic codes. 当有限域的特征不整除群的阶时，给出了直接写出相应的多项式环的本原幂等元的方法，从而可以直接写出所有的极小循环码。 - 2
An organic coordination (complexing) compound in which the metal ion is bound to atoms of nonmetals, e. g. nitrogen, carbon, or oxygen, to form a heterocyclic ring having coordinate covalent bonds. 一种配位(络合)化合物，其中的金属离子与氮、碳或氧等非金属原子结合生成有配位共价键的杂环。 - 3
The process of changing an open-chain hydrocarbon structure to a closed ring, e. g. , hexane to benzene.
