| 摘 要： | 1．引言 在数据库领域,由于描述性语言SQL的成功使用,描述性更加受到重视[1,2,3,4]。描述性语言Data-log的提出,使得一些学者认为知识库语言应该是描述性的程序设计语言[4]。然而多年来的研究,不但没有开发出一个描述性的知识库程序设计语言,而且还阻碍了知识库的实用化[5]。本文研究了描述性与逻辑语言、知识库语言之间的关系,提出了三个观点：1)描述性语言是计算不完备的,因此不能作为独立的程序设计语言；2)逻辑语言是描述性语言的合适形式；3)追求语言的描述性是知识库系统实用化的障碍之一。

| Abstract: | Declarative languages are the pursuing goal of knowledge-base systems. However .after a long time research, from 1985 to now. there have been still no declarative knowledge-base programming languages published.and furthermore .this goal has somewhat blocked the practice of knowledge-base systems. This paper introduces the concept of declarative languages,explores the relationship between declarative languages and knowledge-base languages ,and gives our results. |

| Keywords: | Knowledge-base Logic programming .Declarative Languages. |
