中文摘要：

An LRHTS(v)(or LARHTS(v)) is a collection of {(X, B i) : 1 ≤ i ≤ 4(v-2)},where X is a v-set, each(X, B i) is a resolvable(or almost resolvable) HTS(v), and all B i s form a partition of all cycle triples and transitive triples on X. An OLRHTS(v)(or OLARHTS(v))is a collection {(Y \{y}, A j y) : y ∈ Y, j = 0, 1, 2, 3}, where Y is a(v + 1)-set, each(Y \{y}, A j y)is a resolvable(or almost resolvable) HTS(v), and all A j y s form a partition of all cycle and transitive triples on Y. In this paper, we establish some directed and recursive constructions for LRHTS(v), LARHTS(v), OLRHTS(v), OLARHTS(v) and give some new results.

An LRHTS（v） （or LARHTS（v）） is a collection of {（X, Bi） ： 1≤i ≤ 4（v - 2）}, where X is a v-set, each （X, Bi） is a resolvable （or almost resolvable） HTS（v）, and all Bis form a partition of all cycle triples and transitive triples on X. An OLRHTS（v） （or OLARHTS（v）） is a collection {（Y／{y}, Ay^j） ： y ∈ Y,j = 0, 1, 2, 3}, where Y is a （v ＋ 1）-set, each （Y／{y}, Ay^j） is a resolvable （or almost resolvable） HTS（v）, and all Ay^js form a partition of all cycle and transitive triples on Y. In this paper, we establish some directed and recursive constructions for LRHTS（v）, LARHTS（v）, OLRHTS（v）, OLARHTS（v） and give some new results.
