| 摘 要： | 简要阐述了地震预警（报）系统（利用震灾区某点相对震中区地震波的走时差来进行预警）的设计时，并从理论上分析了其在减少人员伤亡方面的功效，8级左右大震其减少人员伤亡率P^－可达到70％以上。进一步的分析计算还发现，震害损失和地震预警（报）系统减少人员伤亡率P^－i的极大值均不在高烈度区和低烈度区，而是在中等烈度区。

| Abstract: | The principle of the earthquake prediction (warning) system is introduced and the system effect of reducing the injuries and deaths is analyzed and the ratio of reducing injuries and deaths ( value) may be beyond 70% in the M S 8 earthquake.It is found that the maximum of the seismic hazard and value are in the middle intensity area,and not in the higher and the lower intensity areas. |
