：专家系统是人工智能的一个重要分支，是研究的热点。研究人员采用了各种各样的语言进行软件的

开发。为了给研究人员寻找更加适合所开发系统的语言，介绍了专家系统的概念和结构，分析了几种常见的专家

系统开发语言，比较了其优缺点，最后给出了不同专家系统的开发建议。-Expert system(ES) is an important branch of artificial intelligence(AI) which is the

burning point for researchers. The researchers use various software languages to develop an ES. In order

to help researchers to find a more suitable language to develop system, the concept and the structure of

expert systems were introduced. In addition, several common expert system languages developed were

analyzed. And also their advantages and disadvantages were compared. Finally some proposals for

different expert system development were suggested.
