中文摘要：本论文主要研究了具有非局部源的半线性抛物系统并附加Dirichlet零边值的解的性质，得到了系统古典解的渐近性分析：blow-up速率、blow-up集、边界层估计等问题。

The main problem studied in this thesis are properties of positive solutions to a semi-linear parabolic system with non-local nonlinear sources and null Dirichlet boundary conditions. We give the analysis about asymptotic property: blow-up rate, blow-up set and blow-up profiles.

Coming to light, the inhomogeneity of the fluvial facy is more complex than that of delta facy, this mainly is because the cause of formation and mechanism of the mudstone interlayer, distinguishment and distribution in the reservoir are more complex apparently.

众所周知，河流相储层中的非均质性要比其它如三角洲相复杂得多，这主要是由于储层内部中泥质隔夹层的成因机制、识别及分布特征的影响因素较为复杂有关。

There are two classes of flow velocity estimation methods: Doppler frequency shift based methods and velocity—time delay based methods.

基于超声射频的血流运动估计方法主要有两大类：基于多普勒频移的流速估计方法和基于速度—时移的非多普勒方法。

As the equation of the curve determined by companion centers shows, our main result is that the set of all companion centers of a nonisosceles triangle is the unique equilateral hyperbola, called the hyperbola of , passing through the vertices ,, and the barycenter of .

Guided by the theories of exocentric-endocentric construction and decategorization of nouns, the main purpose of this article is to study the phrases which are composed by nouns or centered by noun or nouns but not belonged to the category of endocentric constructions in modern Chinese. These noun-centered exocentric constructions have almost lost all of the categorial characteristics of nouns and played the roles of predicate or adverbial modifier or complement in Chinese clauses.

本文主要结合离心结构、向心结构理论和名词非范畴化理论；研究现代汉语中以名词构成或者以名词为核心的、结构上又不属于向心结构的短语，这些名核离心结构短语在语法功能上基本丧失了名词的范畴属性，在句子中一般充当谓语、状语或者补语。
