B-score

Let G be a graph,the binding number of G is defined as bind(G)=min|N_G(X)||X|:Ф≠XV(G),N_G(X)≠V(G)The relationship of binding numbers bind(G) to factional -factors of graphs was discussed,and some sufficient conditions of existence of fractional -factors with the graphs were given.

设G是一个简单无向图,G的联结数定义为bind(G)=min|NG(X)||X|:Ф≠X V(G),NG(X)≠V(G)研究了图的联结数bind(G)与图的分数[a,b]-因子之间的关系,给出了图有分数[a,b]-因子的若干充分条件。

In this paper, we first introduce the fractional B-spline wavelets proposed by Blu and Unser, and discuss their properties and construction method.

本文首先介绍了分数B样条小波的构成及其性质，基于分数B样条小波一维离散Fourier变换公式，推导出了分数B样条小波二维离散Fourier变换公式，从而实现了图像分解和重构。
