The model in this paper takes the form as belowThe main contents and results in this paper are as follows:In section 1, we state our main analytical results on equilibria of the above system. First, several sufficient conditions for coexistence of the steady-state are given by the standard fixed-point index theory in cone. Second, the global structure of the coexistence solutions and their local stability are established by using bifurcation theory. Third, the multiplicity, uniqueness and stability of positive steady-state solutions to this system are derived by means of perturbation theory of eigenvalues, standard regularity theory, Sobolev embedding theorem and fixed-point index theory.

本文主要有两章内容：第一章研究了该模型正平衡解的性质，可分为三部分：第一部分运用极值原理、上下解方法和锥映射不动点指标理论得到正平衡解存在的充分条件；第二部分利用分歧理论给出了平衡态系统正分歧解的结构，并讨论了局部分歧解的稳定性；第三部分利用特征值扰动理论、标准椭圆正则化理论、Sobolev嵌入定理及指标理论讨论了正平衡解的多重性、唯一性及稳定性，并讨论了参数对解的影响。

Since the 1960s,the leading shipbuilding countries begin to study on the ship condition monitoring and trouble analysis, Nobodys engine-room shipping on duty appeared .certainly the condition monitoring and trouble analysts system also meets some question ,such as: only give alarm or show the actual value of the parameter, does not possess the function of analyzing and giving operator the direct suggestion function about the complicated trouble reason , Only monitor the present running conditions, does not possess the function of predicting equipment future and run reliability though trouble analysis technology makes good progress in these yeas, onboard the ship is still rare .aiming to improve the shipping safety, this paper make some research work on the ship engine-room, the main innovation are as follows:Firstly, this paper introduces and analyzes the research work and current situation on the condition monitoring, trouble analysis and safety assessment .especially in the maritime fields .

船舶机舱系统结构复杂，故障源多，征兆参数丰富，故障与征兆之间常常不存在简单的对应关系，而是相互影响，关系错综复杂。60年代以来，世界上先进的造船国家都相继开展了船舶机械状态监控和故障诊断的研究，出现了无人值班机舱船舶，但仍存在不足之处，如：只给报警提示或显示参数的实际值，不具备对复杂故障的原因分析并给操作者以直接的提示或建议功能；只监测当前的运行状况，不具备预测设备未来运行可靠性的功能；尽管近年来设备故障诊断技术得到了很大的发展，但真正能成功应用于实船的尚不多见。本论文以船舶机舱为对象，以提高船舶营运安全性为目标，来研究船舶机舱的安全控制技术，主要内容如下：首先，介绍和分析了状态监测、故障诊断和安全评估的研究内容和现状，尤其是在船舶领域的研究近况。

The main works are as follows: 1 The developingt history of the traffic load on bridges is represented. Typical bridge codes in some countries are discussed and these traffic load models are comparative analyzed. Analysis shows that the influence of layout axle for the total traffic load effect on bridge gradually becomes smaller with the increase of bridge span. So most national norms use the distributed load as the equipollent load of traffic load.

主要内容包括下面几个方面： 1阐述了桥梁汽车荷载发展的简史，讨论了部分国家典型的桥梁汽车荷载设计规范，并对这些荷载模型进行了对比分析，分析表明随着桥跨的增大，车轴布置对桥梁整体荷载效应的影响逐渐变小，因而大部分国家的规范都把均布荷载作为车辆的等代荷载。

The results of the study are as follows: 1 Wigner′s time-frequency analysis of the geoacoustic signal is of a clear physical meaning, which can be described as the energy distribution in time and frequency domain, and can reveal the frequency spectrum essential features of non-stationary geoacoustic signal.

研究表明：1。地声信号的Wigner时-频分析具有明确的物理意义，它可表述为信号在时间和频率域上的能量分布，揭示了非稳态地声信号频谱的本质特征。

This thesis focus on the issue of "configuration and evolution in urban residential space" with its motif as follows: whatever phase a city is on urban space is both a "geographical space" and "social space" with the former to be exterior formation and the latter essentialness, which impart the differentiation of residential space to be incarnate of social stratum indicating human relation and that of social group as well, hence engender the "geo-social dialectic".

论文围绕着"城市居住区空间结构模式演化"为主线来展开，中心思想是：无论在城市发展的那个历史时期，城市居住区空间既是一种"地理空间"，同时也是一种"社会空间"，前者是外表形式，而后者是内在实质，城市居住区空间的"分化"现象是城市社会等级结构的外在体现，实质上是人与人以及社会群体之间关系的反映，从而形成"社会空间统一体"。
