　　This book mainly discusses the degree factors and the component factors in graphs， and is divided into five chapters.In c.hapter 1， we give the basic terminologies， definitions， graphic parameters， background and significance of the study. In chapter 2， we discuss the existence of fractional factors with given properties in graphs.In chapter 3，we present some definitions related to all fractional factors of graphs and derive some results for graphs to admit all fractional factors.In chapter 4， we study orthogonal factorizations in graphs or digraphs which are natural improvements and generalizations of the previous results.In chapter 5，we study component factors of graphs and gain some interesting results on the existence of component factors in graphs.This book is a useful reference for college students and graduate students.
