It is proved in this paper that for arbitrary positive number A, a pure Handcuffed triple system NH(v, 3, λ) can be embedded in a pure Handcuffed triple system NH (u, 3, λ) if and only if A(v- 1 )≡λv(v- 1 ) ≡λ(u - 1 )≡λu(u - 1 )≡0 (mod 4), u≥2v+ 1, λ≤2 (v- 2 ) /3.

The following results are obtained:(1)There exists an indecomposable pure MTS( v,3 ) for v =9,10,12,13,15,16.

证明了：（１）对ｖ＝９，１０，１２，１３，１５，１６，存在单纯不可分的ＭＴＳ（ｖ，３）；（２）对一切ｖ≥６，存在单纯不可分的（ｖ，４，２）－ＰＭＤ。

Let Q={v:there exists a pure (v, 4,1)-PMD whose underlying B(4, 3;v) is indcomposable}.

设Ｑ＝｛ｖ：存在单纯的（ｖ，４，１）－ＰＭＤ，其基础设计Ｂ（４，３；ｖ）是不可分的｝，则ｖ∈Ｑ的充要条件是ｖ≡０，１（ｍｏｄ４），ｖ＞１且ｖ≠４或８。
