摘　　要：本文仔细分析了我国宽带地震仪记录和论文"汶川大地震宽带地震仪短临异常及成因初探"提供的数据,探讨了5.12汶川8.0级强烈地震前后记录的"异常"现象,对该论文观点提出了质疑.有理由推测,该"短临异常"并非地震前兆,它最可能是在此期间在西太平洋的02号强台风"威马逊"激发的脉动异常.We analyses the data of the paper ＂The short term anomalies detected by broadband seismographs before the May 12 Wenchuan earthquake, Sichuan, China＂ and investigate the anomaly records on the seismic observation stations before and after this earthquake. There are reasons to make an argument to that paper and to prove that this ＂short anomaly＂ is not earthquake auspice. It probably is the microseisms anomaly caused by the 02 typhoon Weimarxun （Ramasun）of 2008 in the region of the west Pacific.
