On the basis of P. Kelly's theorem, in §1—§5 the writer investigates at large the r. c. from the structural form in which the(n—2)—order derived subgraphs of a n-Points graph G occur in G. With the concepts of the structural matrix, the column-symmetry-preserving rearrangement of a symmetrical matrix, etc., We first establish some proposition equivalent to the r. e. Then, from the froms of the structural matrices, we pick out some classes of graphs (which include the P. Z. Chinn's result[12]as a particular case), of which the reconstructions are unique, and the essential diffieulties in the general case from the viewpoint of the structural matrices are analized. In §6, the reconstructions of partial labeled graphs, the problem of uniqueness of coloring graphs and the relationship between them are discussed. In §7 P. Kelly's theorem is extended to the hypergraphs. The problems and conjectures presented in this paper may stimulate a new approach to the r.c. and the problems related to it, and some of them may be of independent meaning in graph theory.

§1—§5中,在P.Kelly定理的基础上,从n点图G的所有n-2阶导出子图在G中出现的结构形式来对重构猜想作一般的探讨。使用标号图的结构方阵等概念,建立重构猜想的一些等价命题。从结构方阵的形式划分出一些重构唯一的图类(其中包括P.Z.Chinn[12]的结果),并分析一般情形的根本难点。§6中讨论部分标号图的重构与图的着色唯一性问题。§7中把P.Kelly定理推广于超图。文中各节所提出的一些问题与猜想,希望对于重构猜想提供一些新的思考途径,有些猜想在图论中有它的独立意义。

Coloring is an important realm it the graph theory. After the four-color theorem has bean verified, there still remains a hard nut to crack that what plane graph can be three-coloring. Fot this problem,there is now a solution: if the graph is Eulerian maximal plane graph, then x(G)=3. On the basisof studying 0-1 cycle sequence, this paper gives our the necessary and sufficient conditions for a plane graph G with x(G)=3.

染色问题是图论的一个重要领域,在四色定理得到证明[1]之后,仍然存在“什么样的平面图 可以3-染色?”这样的难题[2].目前已有结果:“欧拉极大平面图G有x(G)=3”[3]、[4],本 文在研究0-1循环排列的基础上给出了平面图G有X(G)=3的充要条件.

In this paper,a model-interval colouring of graphs was introduced,a polynomial algorithm for interval colouring of comparability graphs was presented and the algorithm for coloring of graphs was improved.
