Objective:to determine the value of ultrasound in diagnosing fatty liver and analyze its cause.methods:using ultrasound as diagnostic tool,we analyzed the pathogenesis of fatty liver in 2 350 patients,and at the same time,we recorded their heights,weights,blood lipids levels,blood-sugar levels,drinking time and occupation,et al.results:these was prominent performance in ultrasound examination of fatty liver,and it had high incidence in patients who was overweight,normolipidaemic,hyperglycemia,dipsomania and mental workers.

目的：探讨超声对脂肪肝的诊断及对分析其起病原因的价值。方法：用超声作诊断工具，分析我门诊部2 350例体检病人的脂肪肝发病情况，同时记录病人身高、体重、血脂、血糖、饮酒、职业等。结果：脂肪肝的超声检查有较突出的图像表现，超重、高血脂、高血糖、长期饮酒、脑力劳动者有较高的发病率。

The thesis puts forward intensive definitions of three types of relations and their consistency. By building the corresponding model based on graph theory, it studies the consistency property of relations, and brings forward three static consistency validation methods with the assistance of graphic connectivity, directed path, accessibility et al.

The first part presents develops of predator-prey systems and gives the model that is investigated in our paper; Chapter 2 presents the results on boundedness of solutions and permanence of system; In chapter 3, we explicitly derive a domain of attraction for the positive equilibrium of system by using Liapunov method; The local stability and the conditions that Hopf bifurcation occurs are obtained in chapter 4; In chapter 5, some explicit fomulae of the direction of Hopf bifurcation and the stability of bifurcating periodic solutions on the center manifold are determined,using normal form and center manifold introduced by Hassard et al; In chapter 6, some numerical simulations are performed to illustrate the analytical results found; Our paper ends with a brief conclusion.
