Let p denote an odd prime, let O denote the ring of integers of a finite extension K/Qp, let λ denote its maximal ideal and let k = O/λ.
---- p 是大于2的素数, O 是有限扩张K/Qp的整环, λ是它的最大理想, 令 k = O/λ.
---- 主角儿是 O (某种整环).其它是配角儿.
---- 简记 O(K/Qp, λ, k). 或给出“图解”:
O k
.
K/Qp λ

第二段.(逐句评论)
If L is a perfect field GL will denote its absolute Galois group and if the characteristic of L is not p then eps: GL --> Zˣp will denote the p-adic cyclotomic character.
---- L 是美域, GL 是绝对 Galois 群; 若 L 的特征非p,则 eps: GL --> Zˣp 表示 p进制分圆特征.
