摘　　要：以JB4708-2000《钢制压力容器焊接工艺评定》标准释义为基础,构造焊接工艺评定流程模型,重点对焊接工艺评定的必要性作出判断,解释并例举对标准中规则知识的总结和表达,并写入SQL(结构化查询语言语句),建立知识库。实现对所要求的焊接条件根据替代规则对PQR(焊接工艺评定报告)数据库进行合理搜索,得出符合输入条件的PQR。The welding procedure qualification process model and the necessity of welding procedure evaluation was set up and estimated based on the standard interpretation of JB 4708-2000 《Welding procedure qualification for steel pressure vessels》.The rules of the standard summary of knowledge and expression was explained,and then written to the SQL（Structured Query Language）,a knowledge base was set up.The reasonable searching from PQR（Welding procedure qualification report） database was achieved under alternative rules,and the PQR which can meet the input condition was gotten.
