摘　　要：一个三元系若不包含重复区组,则称为单纯三元系.本文运用嵌入技巧与差方法完整地解决了单纯3重三元系的相交数问题.A triple system is called simple if it contains no repeated blocks. In this paper, the intersection problem was completely solved for simple three fold triple systems, by using embedding technigues and the difference method.

关 键 词：单纯三元系 相交数 差三元组 嵌入
