| 中文摘要: |
| 消防队接到火警后第一出动力量及时到达火场展开灭火救援，对有效控制火灾、减少人员伤亡和财产损失有着重要的意义。第一出动时间直接反映了城市灭火救援专业力量的出动响应水平。采用SPSS软件对1995-2003年日本全国城市火灾数据进行分析，发现第一出动时间的频次符合对数正态分布；与部分中国城市火灾统计数据对比后，表明后者符合同样的规律。中国数据对数正态分布的期望值为4.9分钟，其物理意义为消防力量第一出动时间的平均值，与我国消防条例对城镇消防站设置的基本原则相符。 |
| 英文摘要: |
| Arrival of firemen at the fire scene instantly after they receive the alarm is of great significance for controlling the fire and reducing the casualties and property losses. The first response time T(subscript F) represents the response efficiency of firemen. Fire statistical data of Japan from 1995 to 2003 are analyzed by SPSS and it is found that the frequency of T(subscript F) fits well with the log-normal distribution, as can be verified by the results of the P-P verification and the U verification. The correlation coefficients of the data fittings are all higher than 0.9. The fire statistical data of a city in China from 2000 to 2009 shows the same law. The expected value of the log-normal distribution represents the statistical average of T(subscript F). The results may be used in the optimization model for the location-allocation of fire stations. |
