【摘要】 对湟源地震台周边各种因素所致的地震记录干扰情况进行了分析,认为干扰源主要有采石场爆破、灌溉水渠、小河、车辆干扰及各种天气及固有干扰等。根据这些干扰源的频谱特性,采用MATLAB语言,设计、编制了不同类型的滤波器,在震相识别上发挥了很大作用。更多还原

【Abstract】 The interferes caused by various factors around Huangyuan seismic station are analyzed,and the sources are explosion in the quarry, water channels,rivers,vibration due to traffic,fluctuation of climate and others.According to their spectral features,the authors use MATLAB language to design different filters which play an important role to phase identification.更多还原
