摘　　要：选取乌鲁木齐区域数字遥测台网中 1 1个子台的背景噪声数字记录 ,计算并分析其背景噪声地动速度均方根值 RMS、有效测量动态范围以及噪声功率谱 。The digital records of the noise background are selected from 11 substations in the Urumqi Digital Telemetered Seismic Network, and the RMS (root-mean-square value of ground surface motion noise), effective dynamic surveying range and noise power spectrum are analyzed and calculated. The frequency bands at every sub-station in which the background noise is relatively concentrated are determined.

关 键 词：背景噪声 噪声功率谱 数字遥测台网 乌鲁木齐市 地震信号 风 气温 气压
