摘要
给出了λ≤3时(q,3,λ)-差族存在的条件。利用一种特殊Langford序列中的完美Langford序列、带洞Langford序列的定义及其存在的充分必要条件完成了差族的构造。
The existence conditions of the （q,3,;λ）-difference family were given. A possible （q,3,λ）-difference family was constructed by the definitions and the necessary and sufficient conditions of several special Langford sequences, such as perfect Langford sequence, hooked Langford sequence.
