摘　　要：利用大连地震台日常观测数据,对比人文噪声干扰强弱时段的噪声功率谱密度和地脉动噪声均方根(Root Mean Square,RMS)值等数据,分析干扰噪声的频谱特征。针对干扰频段进行滤波,以提高测震波形质量,清晰识别地震事件。Based on the daily observation data of Dalian seismic station,this paper compares the noise power spectral density and ground pulsation noise Root Mean Square(RMS)value in the strong and weak period of human noise interference,and analyzes the spectral characteristics of interference noise.Filter the interference frequency band to improve the quality of seismic waveform and clearly identify seismic events.
