摘　　要：通过对六安台观测系统速度与加速度记录台基噪声谱密度以及频响特性测定,分析了两个观测系统记录地震波参数所具特征,并通过震例加以说明,为提高台站地震分析能力与开展台站烈度速报工作提供技术依据。By measuring base noise power spectrum density and frequency response of velocity and acceleration recorded by Lu＇An station observation system, this paper analyzes seismic wave parameters characteristics of two observation systems, and further illustrates with earthquake examples, which provides technical basis for improving analysis capability and intensity report operation work in observation stations.

关 键 词：速度 加速度 特征参数 烈度速报
