中文摘要：

对更新过程进行探讨，推导给出几个与更新过程有关的概率分布及其数字特征，进而将一般更新过程特殊化为齐次泊松过程，得出几个相应的推论．这些分布和推论在刻画城市交通流和行人流中都有重要应用．

英文摘要：

The renewal process is discussed, some probability distributions and its digital character associated with the renewal process are derived, then the general renewal process special into the homogeneous poisson process, several similar conclusions are given. These distributions and inferences have important applications in the characterization of city traffic flow and pedestrian flow.
