【摘要】 地震台站方位角的准确性对地震监测与研究至关重要，方位角偏差会直接影响地震波形的解读和地震事件的科学分析。本文利用Python编程语言，基于切向能量最小法原理，对收集的黑龙江地震台网38个地震台站记录的地震波形数据开展方位角偏差计算。结果显示，黑龙江地区不同地震台站的方位角偏差存在显著差异，部分台站偏差较大，最大偏差达68.9°。本研究得到的方位角偏差结果，为黑龙江地震台网台站方位角校正提供了依据，有助于提升地震监测数据的可靠性。更多还原

【Abstract】 The accuracy of seismic station azimuths is crucial for earthquake monitoring and research, as azimuth deviations directly affect the interpretation of seismic waveforms and scientific analysis of earthquake events. By collecting waveform data from 38 stations in the Heilongjiang Seismic Network, we calculated azimuth deviations using tangential energy minimum method. The results revealed significant variations in azimuth deviations among different stations in the Heilongjiang region, with some stations showing substantial deviations reaching up to 68.9°. The azimuth deviation results obtained in this study provide a basis for the azimuth correction of stations in the Heilongjiang Seismic Network and help improve the reliability of seismic monitoring data.更多还原
