Chapter Ⅰ reviews the results of previous research and states the origin, the meanings and the methodology of the dissertation. Chapter Ⅱ interprets the definition of"culture", the basic consciousness of traditional Chinese culture, Characteristics of culture of HK and cultural elements of modern society. Chapter Ⅲ probes the cultural elements of language itself and points out that"features of language","use of metaphor and analogy"and"theme and idea"are its three essential and linked layers which are the most proper channels to infiltrate cultural education. Furthermore, this chapter also compares and contrasts the inner meanings of the syllabus of China and HK. Chapter Ⅳ analyses the model essays of both China and HK through the concept of"features of language","use of metaphor and analogy"and"theme of idea". It also compares the ways of editorship towards the selection of model essays between China and HK. Chapter Ⅴ compares the methods of model essays teaching between China and HK so as to explore its insides meanings of culture. Chapter Ⅵ reasserts the importance of infiltration of culture education into language education and states the limitations of this dissertation. This dissertation counters the existing defects that caused by the over-emphasis of instrumentalism and affirms the importance of infiltration of cultural education into language education.

第一章讲述研究的源起、意义和方法，指出香港在殖民地时期的语文教育状况，及回归后在语文教育中渗透文化教育的重要意义，并列出前人的研究及本文的研究方法；第二章探讨文化的定义，讨论中国传统文化的基本精神，香港文化的特色及现代社会的文化成分；第三章讨论语文本身的文化成分，指出其内含三个层面：&语言特色&、意象连用及&主题思想&；语文及文化关系密不可分就表现在这三方面的紧密联系上面，并冀望教师从这三方面入手，通过语文教育渗透文化教育，此外，又比较内地和香港语文课程大纲的异同及背后所反映的不同意义；第四章从&语言特色&、&意象运用&及&主题思想&三个层面分析内地与香港语文科选文的内容，供教师参考，又比较两地选文及编选手法的特色；第五章比较内地与香港教师就范文教学的课堂处理手法，及从中透显的文化意涵；第六章总结及建议，一方面重申语文科渗透文化教育的重要性，期望教师注意，另方面也指出本研究的限制所在。

In this paper,The effection of hybrid fibers including steel fiber,Dura fiber and Dolanit fiber as two elements or three elements on the mechanical properties and impermeability of high-performance cementitious matrix with the composite of high percentage pulverised steel slag and expansive agent are investigated systematically.

研究了钢纤维、Dura纤维和Dolanit纤维按二元或三元混杂对大掺量磨细钢渣与膨胀剂复合的高性能水泥基复合材料的力学性能和抗渗性能的影响，从不同尺度与不同性质的纤维在相应结构层次上的叠加效应角度来阐述水泥基复合材料的防渗抗裂机理。

1 Visual Basic Introduction Visual meaning "visualization" refers to a development of graphical user interface way of using this method, the programmer need not write code for a large number of interface elements to describe the appearance and location of as long as the pre-establishment of a good interface elements (such as buttons, list boxes, labels and the like) to the screen with the mouse drag and drop the appropriate location.

2.1 Visual Basic 简介 Visual 意为&可视化的&，指的是一种开发图形用户界面的方法，使用这种方法，程序员不需编写大量代码去描述界面元素的外观和位置，只要把预先建立好的界面元素（例如按钮、列表框、标签之类）用鼠标拖放到屏幕的适当位置即可。

We use zero to mark available elements of heap; therefore, we cannot return a reference to heap[0] — if it were a set, its elements would contain the index value zero.

我们用0值来标识heap数组中可用的成员；所以不能返回heap[0]的引用——因为如果它是一个集合，那么它所包含的元素可能包括索引值0。

The paper describes the selection principle of primary schemes for C-GIS and determines the general structure arrangement by comparing different elements and box structure, analyzes the insulating characteristics of SF6 gas and calculates the SF6 gas clearance and along surface insulation. It puts forward the factors that should be considered and strength analysis methods when designing gas chamber structure and analyzes the reasons of influencing the temperature rise of gas chamber and offers the ways of radiating. The vacuum circuit breaker and three-position disconnector are designed for C-GIS and special micro-computer controller for the three-position disconnector is developed. On the basis of new type sensors, suitable control and protection system for C-GIS is suggested. The type test items for C-GIS and its internal elements are introduced to prove that the development is successful.

Based on the detailed analysis of existing dimension recognition methods, this paper concluded a common limitation of existing methods-"single-entry recognition", which has three distinct drawbacks. First, the only recognition entry reduces the capability to handle drawings of different qualities; second, the fixed search order for dimension elements block algorithm seeking all possible ways to find a dimension structure; third, single directional recognition of graphic elements uses no drawing context and thus can not make use of engineering knowledge.

本文分析了现有的尺寸识别方法，指出它们共有的局限性——单入口的识别过程：单一的识别入口限制了算法对不同质量图纸的适应能力；固定的元素搜索顺序阻碍了算法利用一切可能的途径寻找和识别尺寸标识结构；单向的独立于上下文的图形元素识别忽略了应用领域知识对识别过程的启发作用。
