摘　　要：通过对唐山地震等大量震例和震害资料的分析，总结出适合于地震预报单级模糊决策具体计算使用的参数表。根据这些表列出的参数计算的结果，在１９８４年５月２１日南黄海６２级和１９９６年１１月９日长江口以东海域６１级地震的震后快速趋势判定中，均取得了相当好的社会效果，在对１９７５年２月４日海城７３级和１９７６年松潘７２级地震的内检中，也取得了很好的结果。By analyzing a large number of earthquake examples,e g Tangshan earthquake etc. and earthquake damage data,the computation charts used for the single-stage fuzzy decision calculation suitable for earthquake prediction are summed up in this paper . The results calculated from the parameters listed in these charts were brought into full play in the rapid determination of the post earthquake trend for the South Yellow Sea earthquake of M S6 2 on May 21,1984 as well as the M s 6 1 earthquake occurred at the east of Yangtze River Estuary on Nov 9,1996.Its effectiveness was quite good .Good results were also abtained in theinner_check for Haicheng earthquake of M s7 3 on Feb.4,1975 and the Sangpan earthquake of M s7 2 on Aug.16,1976. For this reason ,this paper presents the specific parameters which have standed the test of several earthquake examples to those persons who are interested in it. It is believed to be considerablely interesting.
