The existence of a large set of pairwise disjoint Kirkman triple systems is an old and interesting combinatorial problem.

中文摘要：两两不交的Kirkman三元系大集的存在性问题是个古老而有趣的组合问题，它源于1850年的"Sylvester 15女生问题"。

The problem on the existence of large sets of Kirkman triple systems is one of problems in combinatorial designs theory, which is of long history and hard to study.

Kirkman三元系大集的存在性问题是历史悠久且研究最困难的组合设计问题之一。

In chapter six,we discuss the maximum embeddings for nearly Kirkman triplesystems.With at most 14 possible exceptions,we completely solve this problem.

第六章我们讨论了拟Kirkman三元系的最大嵌入问题，除14个可能的例外，我们完全解决了这一问题。

When 〓,weget two special and important cases,that is,the embedding problem for Kirkmantriple systems and the embedding problem for nearly Kirkman triple systems.

关于〓的RGD的嵌入问题，有两种情形特别重要，其一即是Kirkman三元系的嵌入问题，这一问题已由R。

In chapter three,we construct some types of GDDs and Kirkman frames,whichis used in the later chapters for the construction of nearly Kirkman triple systems withsub-systems.

在第三章中我们构造了相关的GD设计及Kirkman frame，为我们具体研究拟Kirkman三元系嵌入问题提供了有力的工具。

In section 3 and section 4, We obtain other Kirkman frames by giving weights to some types of GDDs with block size at least 4. Finally, through using recursive and"filling hole"constructions, we give a complete solution to the embedding problem of resolvable minimum coverings of pairs by triples.

在第三节与第四节中，我们利用已知的特别有用的一些Kirkman frames、再利用已知存在的区组长至少为4的可分组设计通过加权后构造出另一系列Kirkman frames，最后通过递归和填洞构造法，解决了λ=1时可分解最小覆盖三元系的嵌入问题。

It is well known that a resolvable maximum packing with triples of order v with index λ=1 is a nearly Kirkman triple system KTS if v≡0 (mod 6), so the whole embedding problem for resolvable maximum packings with triples for arbitrary index λ has been completely solved.

由于指数λ=1且v≡0（mod 6）时一个v阶的可分解最大填充三元系即为一个v阶的拟Kirkman三元系，所以对一般指数λ的可分解最大填充三元系的嵌入问题已全部解决。

In 1984, Kirkman and Gaetani (1984) reported tightly bound NADPH in BLC, which then was also detected in the X-ray structure of BLC (Fita and Rossmann, 1985a). In the course of various sequencing projects a broad spectrum of catalase sequences from organisms of all kingdoms appeared in the public databases in the last 17 years e.g.

Vainshtein等获得了在3.5A 低等真核细胞中的过氧化氢酶的第一个电子云图，同时Eventoff 也得到了在2.5A处，用X-ray详细分析附面层控制图，1984年Kirkman 和报道了 Gaetani BLC中的紧密结合的还原型烟酰胺腺嘌呤二核苷酸磷酸

For the embedding problem of nearly Kirkman triple system,the only resultknown was:These exists an NKTScontaining an NKTSwhen 〓〓.

关于拟Kirkman三元系的嵌入问题，原先仅有如下结果：〓且〓，〓时，存在某个NKTS包含一个NKTS为子设计。
