通过系统清理１９９６年以来中国大陆７０个Ｍｓ≥５．５级地震序列的＂强余震＂Ｌｇ△ｔ－Ｌｇｔ关系，对强余＂等待时间＂判别方案预报效能进行了评估。结果表明，其回顾性预报的Ｗａｌｌｅｎ评分为：６级以上地震序列Ｖ＝０．６０，５．５级以上地震序列为０．４４，说明其在地震序列类型判断方面有一定的效能。对实际震例分析得出，该方案在判定主余型序列方面成功率较高，而对于双震或多震序列，有时会产生某些误判；对６级以上地震序列的预测成功率高一些，对低震级的序列判断应慎重。
By systematically cleaning up the “strong aftershock” Lg △ t-Lgt relationship of 70 Ms≥5.5 earthquakes in mainland China since 1996, the forecasting effectiveness of the “waiting time” discriminant scheme was evaluated. The results show that the retrograde Wallen ’s scores are as follows: the V = 0.60 earthquake sequence above the 6th grade and the 0.50 earthquake sequence above the 5.5th grade, indicating that it has certain efficiency in judging the type of earthquake sequence. According to the analysis of actual earthquakes, the success rate of this scheme is high in judging the main residual sequence, but some misjudgment sometimes occurs in the case of double or multiple earthquake sequences. The success rate of prediction for earthquakes with magnitude 6 or above is high Some, the judgment of low magnitude sequence should be cautious.
