根据Ａｌｅｎ的时间世界理论，提出了具有因果关系的事件间的时态关系类型、时延区间、时态范围及可接受性等概念，导出了可接受时态范围之间的各种约束及相互关系。结合ＴＣＤＭ因果诊断模型，分别就时态信息描述、时态信息传播的一般过程、时态一致性检验、时态信息传播的算子等进行了研讨，并给出相应的方法及性质。 According to Alen’s time-world theory, this paper proposes concepts such as types of temporal relations, time-delay ranges, temporal extents and acceptability among incidents with causal relationships, and derives various constraints and interdependencies between acceptable tense ranges relationship. Combined with TCDM causality diagnosis model, this paper discusses the description of temporal information, the general process of temporal information dissemination, the test of temporal consistency and the operator of temporal information dissemination, and gives corresponding methods and properties.
