摘要
系统地研究了事件对称差的性质，揭示了ｎ个事件对称差的实质，提出了关于若干个事件对称差的概率计算公式，最后引入了一个新的由对称差的概率所产生的距离。
The symmetric difference of the events is deeply discussed,its properties ofoperation are sys temtically researched the essence of the symmetric difference of the nevents is revealed, the formula of the probability calculation with respect to the symmetricdifference of the n events is given, and a new distance generated by the probabili ty of thesvmmetric difference of the events is introduced.
