摘　　要：人们对领域知识、系统目标理解存在差异,对领域需求表述不规范,而导致软件需求不一致和频繁变更。为了解决这一问题,提出一种基于受限语言的领域需求描述方法,通过设计受限语言的需求获取模板,规范表示领域需求,通过词汇合法性检测和句型匹配,保障领域需求描述的正确性,并采用XML文件保存领域需求。最后通过构建实例验证了该方法的有效性。Abstract： People have different understanding about domain knowledge and system goals, and expressed demand for software is not standardized, so that the domain requiremented are often inconsistent and have to be changed frequently. This paper presented a method of domain requirements description based on limited language, by designing the restricted language re- quirement template to descript domain application needs. Then it checked the legality of vocabulary and matching the sentence patterns to verify the correctness of domain requirement description. And it saved the domain requirement in XML files. Final- ly it built instances to verify the effectiveness.
