Thus the spectrum of intersections for simple threefold directed triple systems was determined.

证明了对于任意正整数ｖ≥３，存在两个ｖ阶单纯三重有向三元系相交于ｓ个公共有向三元组的充要条件是：当ｖ＝３时，ｓ∈｛６｝；当ｖ＝４时，ｓ∈｛０，１，２，…，１２｝＼｛１，１１｝；当ｖ≥５时，ｓ∈｛０，１，２，…，ｖ（ｖ－１）｝＼｛ｖ（ｖ－１）－１｝，从而完全确定了单纯三重有向三元系相交数的

The intersection problem of simple directed triple systems with λ =2 is completely solved, namely, it is proved that for v ≡0,1 (mod 3), v ≥3,there exist two simple DTS( v ,2)s intersecting in s triple if and only if, s∈{0,1,2,…,2v(v-1)/3},s≠[2v(v-1)/3]-1, while v≥4 s∈{0,2,4},while v=
