| 摘 要： | 在分析火灾发生概率规律性的基础上,可在一定的置信水平上,对火灾发生的起数进行区间估计和假设检验。通过区间估计将未来的火灾形势预测为一个置信区间,通过假设检验可排除随机干扰,确定火灾发生起数的变化规律,这些信息都能为消防规划的制定提供科学的数量依据。

| Abstract: | In the base of analyzing of fire disaster occurrence probability characteristics, the occurrence frequency of fire disaster of a given district can be estimated and predicted as a confidence interval at a giving confidence level, and the hypothesis testing can also be made. This information can be a helpful quantity basis for fire protection programming. |

| Keywords: | Fire disaster Negative exponential distribution confidence level Confidence interval hypothesis testing |
