摘　　要：在最短的时间内,准确的报出地震三要素,是速报工作的关键。经过对所选的速报地震进行分析定位后,发现在速报中,所选台数是至关重要的,在以包围震中为原则的前提下,一般网内与网缘地震所选台数在7个台,网外地震所选台数在7～9个台,这样的速报结果与新疆地震目录结果最为接近。The crux of quick report of earthquakes is to determinate the three factors of earthquake as soon as possible.Through the analysis of selected earthquake location reports,it was found that the number of stations for quick report is crucial.Under the condition of around the epicenter,7 for earthquakes within or near the margin of network,and 7-9 for earthquakes outside of the network are the optimum number of stations,as the result of quick report are the closely similar with those of Xinjiang earthquake catalog.
