| 摘 要： | 利用兰州地震台阵与兰州地震台数字化近两年的资料,对地震震相特征和震级进行对比分析,结果发现：地震记录震相特征基本相同,台阵有压低干扰背景和突出地震波信号的功能,说明台阵对记录较微弱地震有优势;在震中距小于1 000 km的范围内,兰州台阵的监测能力较明显高于兰州台,而震中距大于1 000 km时,兰州地震台阵与兰州地震台的监测能力相当.

| Abstract: | Using the past two years data of Lanzhou seismic array and Lanzhou Seismic Station,we contracted and analyzed seismic phases features and magnitude.The results show that：①the features of seismic phases between Lanzhou seismic array and Lanzhou Seismic Station are almost the same.However,seismic array have the advantage of recording weaker earthquake,since it can efficiently suppress background noise and interference; ②when epicentral distance less than 1 000 km,monitoring ability of Lanzhou seismic array is significantly higher than Lanzhou Seismic Station,while the epicentral distance is greater than 1 000 km,the monitoring abilities of two are roughly equal. |
