摘　　要：定性模拟（ＱＳ）是近１０年来从人工智能中发展起来的一种模拟技术．本文从状态空间的角度讨论了定性模拟中的一些基本概念，在定义定性轨迹的基础上，首次从定性状态转移的角度阐明了定性模拟过程中产生新界标的重要性，同时还给出了定性稳定性的概念和判别条件。Qualitative simulation (QS) was a technique initiated from AI in the last decade. In this paper, we discussed some basic concepts of QS in terms of state space, and based on the definition of qualitative trajectory, we first clarified the importance of creating new landmark during the simulating process in terms of qualitative state transition, meanwhile, we also proposed the concept of qualitative stability and provided the judgement condition for qualitative stability, which would strengthen the measures of global filtering of QS.
