摘　　要：主要是将包含度拓广应用到区间直觉模糊信息系统的知识获取中。首先给出区间直觉模糊集的包含度概念和公式;然后,利用区间直觉模糊集的包含度给出区间直觉模糊信息系统的知识获取的具体方法,主要包括两方面:一是获取模糊决策规则,二是对信息系统进行属性约简;最后,用实际算例说明了该方法的合理性和有效性。The inclusion degree was used into the knowledge acquisition based on interval intuitionistic fuzzy information systems. Firstly, the concept and the formula of inclusion degree of interval intuitionstic fuzzy set were proposed. And then, the concrete method was given to the knowledge acquisition based on interval intuitionistic fuzzy information system by using the inclusion degree, which mainly includes two aspects： the first is to acquire the fuzzy decision rules, and the second is to reduce the attributes of the information system. Finally, the actual computation example was given to show this method is reasonable and valid.
