Further more , by means of analyzing bios technology , the dissertation expounds the board - level initialization process and key technologies of embedded system . to study the basic principle of bootloader , it gives a detailed statement of gurb based on the source code , and put forward the structure and designing ideas of bootloader in embedded system 通过分析pc机的bios技术阐述了嵌入式系统中板级初始化流程和技术重点,并从源代码分析入手详细分析了pc机gurb引导程序设计技术,提出了嵌入式系统上bootloader的程序结构和设计思想。
The process of programming uses object - oriented programming idea , processes the modularization technology . during the course , the key technology and development are discussed , such as the technology of object - oriented programming , the interface technology of the parametric cad system , the modularization idea , the method of realizing parametering design of cad system , the techniques of arx and mfc combination , the technology of process basic function module , the foundation of database , and so on 在程序设计过程中秉承面向对象的程序设计思想，全文贯穿了模块化设计理念，分析了软件开发过程中的关键技术及实现方法:如面向对象的程序设计技术、参数化cad系统的接口技术、模块化设计技术、 cad系统的参数化设计的实现方法、 arx与mfc联合使用技术、工程数据库的建立以及基本功能模块的开发等等。
Firstly , we give a brief analysis of the merits and demerits of object - oriented technology , introduce ludwig wittgenstein ' s philosophical views on the logical structure of the real world and language , analyze and introduce the features of objects that they will appear different attributes and behaviors in different environments and scenes . then we propose a new programming language named fact - oriented programming that is based on the object - oriented programming and is centered on objects 本文首先对面向对象程序设计技术和它的缺点进行了简要的分析，并扼要地介绍了维特根斯坦关于世界和语言逻辑结构的哲学论述，分析了同一对象会在不同的事实中表现出不同的属性和行为的特点；提出了一种以面向对象程序设计为基础的、以对象为中心的面向事实程序设计思想。
