摘　　要：几乎差族在编码、通信安全等领域有着广泛的应用。本文利用Galois环GR(22, 22s)上一种不相交的差族,通过对差族中某个集合添加一个元素,当满足一定条件时,即可构造出GR(22, 22s)上的几乎差族。The almost difference family has a wide range of applications in coding, communication security and other fields. This paper uses one family of disjoint difference family on Galois ring GR(22, 22s), and by adding an element to a set in the difference family, when certain conditions are met, a new family of almost difference family can be constructed.

关 键 词：GALOIS环 差族 几乎差族
