界面

A careful reader of the "Gang of Four" book will notice that MVC is not referred to as a design pattern but a "set of classes to build a user interface" that uses design patterns such as Observer, Strategy, and Composite.

阿对"四人帮细心的读者"的书会发现，MVC是不是称为设计模式，而是"组类建立一个用户界面"的用途，例如观察，策略设计模式，并综合指数。

Since the existing vehicle driving simulator is lack of incarnating the contents of road sign and Highway Code, the road sense instruction system based on knowledge base is put forward and the detailed road sense database is composed; a simple and practical UI is constituted to make the bald booklore put more road sense into the process of virtual driving.

针对目前汽车驾驶模拟器存在的道路标识、标线及交通法规知识内容体现不足的问题，提出了一种基于知识库的汽车驾驶知识学习系统框架，构建了详细的驾驶知识数据库；建立了简单实用的用户界面，将枯燥的书本知识变得简单生动；同时，将知识库知识与虚拟驾驶模拟器融合，使驾驶知识融入虚拟驾驶全过程。

This is a boon, but it's crudely designed.

这是个很好的功能，只是界面设计还有些粗糙。

The thesis is organized as follows:In Chapter 1,a new partial differential equation model for Spontaneous Potential log in heterogeneous formations is introduced.At the same time,the existence and uniqueness of weak solution to the problem are proved,and the problem of resistance identification in SP log is studied.Furthermore,a jump condition capturing finite difference scheme is proposed and applied to solve such elliptic interface problems.The effects of various factors on SP response,which include objective layers resistivity,bed thickness,bore-hole diameter,invasion and water-flooded zones and so on,are investigated quantitatively by the proposed method, and satisfactory results are obtained.

具体安排如下：第一章首先建立复杂地层中自然电位测井的偏微分方程数学模型，证明了该边值问题弱解的存在唯一性，在此基础上研究了自然电位测井电阻率识别问题：然后发展了用于求解椭圆交界面问题的间断捕捉有限差分方法，利用该方法定量分析了目的层电阻率、地层厚度、井径、侵入带和水淹层等因素对自然电位测井响应的影响，取得了满意的结果。

It solves the imaging problem in great contrast. In chapter 2, the author deeply studies and analyzes the arithmetic of the method of Born approximation inversion and points out the limitations and disadvantage of the method. The good inverse results can be obtained in little disturbance by Born approximation.

本文提出的反演理论，考虑到散射序列中高阶项对成像结果的影响，在反演时利用逆散射序列中的高阶项以弥补散射场数据的丢失，使得在大扰动量的情况下同样能够实现界面位置和形态的精确成像，解决了大对比度情况下的成像问题。

Because of taking only advantage of the first item in scattering series, method of Born approximation inversion is only suitable to little disturbance imaging. And it will produce great error in condition of great perturbation.

考虑到上述问题，本文在Bleistein和Cohen等人对Born近似的深入研究基础上，运用地震逆散射理论进行深度成像，反演地层奇性界面的位置。

The reaction between the boron carbide and aluminum interface changes the properties of the composites during the post infiltration heat treatment.

碳化硼与铝界面的反应是热处理改变碳化硼／铝复合材料性能的基础。

The mostly products in the interface are AbBC which grows along the boron carbide and the boron carbide are attacked by the aluminum.

界面反应的主要产物为Al_3BC，碳化硼被铝侵蚀的同时，Al_3BC等反应产物生成。

On the other hand, in order to contact to practical application and combine the actual experimental condition, we can make some elementary research on the application of boron nitride which has been synthesized.

将合成的纳米氮化硼材料进行表面改性，改善纳米粉体表面的润湿性，增强了其在介质中的界面相容性，使氮化硼纳米粒子容易在有机化合物中分散，提高了氮化硼纳米粉体的应用性能。

In the end, transportation of PAHs in the environmental matrix was preliminarily investigated and discussed according to PAHs data of soils and sediments from a certain region in Shanghai. The result indicated that there are two or more pathways on PAHs transportation in the environmental matrix.

最后，对上海特定地区内PAHs在环境介质中的迁移径途进行了分析讨论，结果表明上海市土壤和沉积物等环境介质中PAHs的迁移存在多种途径。
