| 摘 要： | 本文用泊松分布表示家庭人数的概率分布,并假定在闲暇时间段人在室内的概率服从均匀分布,根据人在一天中的活动建立了不同时间段人在室内的概率公式。用一天中不同时间段人在室内的概率表示地震发生时间对人员伤亡的影响。

| 关 键 词： | 地震发生时间 人员伤亡 泊松分布 均匀分布 |

| Abstract: | The paper uses the Poisson distribution to describe the probability of the family number and builds up the probability formula of people in door in the different time based on the activity of the people in a day to indicate the influence of the original time of earthquake to easualty, supposing that the probability of people in the door in the spare time obey the even distribution. |
