摘　　要：现实世界中事件的持续时间是难以精确测量的,其起始时刻及结束时刻经常是模糊的。本文用事件的持续函数的概念来表示事件的持续时间,并用有限的近似区间的概念来描述无限的持续函数,应用Heisenberg测不准原理,将Allen的区间代数网络的13种基本时态关系压缩为7种基本时态关系,并构造了新的基本时态关系的复合运算表。The durations of events in real world are difficult to measure precisely. The starting points and ending points of events are fuzzy usually. This paper uses the concept of duration functions of events to represent the durations of events. It uses the concept of finite approximate intervals to represent the infinite duration functions. It makes use of Heisenberg＇s uncertainty principle to compress the thirteen basic temporal relations of Allen＇s interval algebra networks into 7 ones and finally calculates the operating table of composition of basic temporal relations.
