Therefore it can support the reuse of higher level of gis component . aiming at the two key technology in gis rcl ? ? classification and searching , the paper discussed emphatically : based on the faceted classification scheme , gis ' s spatial geographic speciality , the integrating speciality of spatial attribute and non - spatial attribute , and requirement of interaction , the paper introduces gis components " classification system . the faceted classification scheme is < level , function , object , style > 论文针对gis组件库的两个关键技术? ?分类和查询进行了重点讨论：基于组件刻面分类策略并结合gis的空间地理特性和空间属性与非空间属性相结合的特性和对互操作的需求建立了适合gis要求的gis组件分类体系，对gis组件提出了<层次、功能，对象，格式>的刻面分类模式。
Then , the syntaxes and semantics of rcl are defined and the process of mental states transition and inter - agent negotiation are described . moreover , after introducing the main problems in mrs architecture briefly , three important architectures - reactive architecture , deliberate architecture and hybrid architecture are discussed 接下来，本文在简要介绍了多机器人体系结构主要解决的问题之后，给出了目前流行的三种体系结构? ?反应结构、慎思结构和混合结构。
Developer is hard to retrieve appropriate component in several rcls simultaneously . it usually takes much time to look for an available rcl and learn the search method , when reuser wants to retrieve several different rcls . the rapid development of internet offers the network condition for distributed retrieve Internet的迅速发展为对分布在不同地理位置上的构件库进行检索提供了的网络基础，软件开发人员希望通过internet对多个构件库进行同时检索，能在更广的范围内选择所需的构件。
This structure is flexible , exoteric and can be expediently expanded to distributing application . from the characteristic of gis component and reuse requirement , the paper perfects the description of gis component : the description includes not only the basic information , but also the affiliated one which supporting reuse . under the sustain of relational database management system ( rdbms ) , gis rcl can store and manage multi - type components 系统结构灵活、开放，可较为方便地扩展为分布式应用；从gis组件的特点和复用需求出发，论文完善了gis组件的描述方式，对组件的描述不仅包括组件的基本信息，还包括支持复用的附属信息；在关系型数据库的支持下，系统可存储和处理多种类型的组件；通过扩展支持组件的类型，系统可以支持高层gis组件的复用。
Etc . for reusers , it cost very much to understand the search methods of rcls , because there are many differences in the category and search methods of components . with rapid increase of rcls , reusers have n ' t been familiar with the search method of each rcl . meanwhile , due to having little in common , each rcls is independent 随着构件库数量的增长，复用者已经不可能熟悉每一个构件库的检索方法，同时，由于构件库之间交互性差，各构件库的构件资源和检索方法对于用户来说都是相互独立的，用户无法有效地对多个构件库同时进行检索，往往为了寻找可用的构件库以及理解其检索方法要花上许多时间。
A typical calculator chip from rcl semiconductor inc , c9821 , is referenced and developed . the chip of the calculator consists of several function units such as rc oscillator , power management module , microprogrammed control unit ( mcu ) , register group , lcd driver and keyboard interface 在硬件方面，在完成计算器的功能模块划分的基础上，对包括rc振荡器、电源模块、 lcd显示驱动模块、键盘接口、寄存器组、微程序控制器在内的各个功能模块的系统结构和电路原理进行了分析，掌握了它们的设计方法。
