Abstract: The conception "almost perfect arrays" is proposed and it is shown that the existence of an almost perfect binary array is equivalent to the existence of a certain divisible difference set. Some methods of constructing perfect arrays are provided. In addition, three conjectures on the existence of perfect arrays are also presented.

Key words: finite fields, almost perfect arrays, divisible difference sets

摘要: 提出了几乎完美阵列的概念,证明了完美二元阵列的存在性等价于一种特定的可分差集的存 在性。提供了一些构造完美阵列的方法。另外,关于完美阵列的存在性提出了3个猜想。
