由于种种原因，台站地震计的固有周期、阻尼、灵敏度、观测动态范围等参数和台基噪声在运行的过程中会发生变化。本文用阶跃标定和计算观测动态范围、台基噪声功率谱的方法，得到吉林测震台网各台站地震计参数和台基噪声的变化情况，掌握吉林测震台网各台站的监测能力，为以后吉林测震台网的建设和发展提出建议。

For all kinds of reasons, the parameters of a seismometer, such as natural period, damping, sensitivity, observational dynamic range, and station base noise will change during observing. In this paper, using methods of step calibration, calculation of observational dynamic range and station base noise power spectrum, variations of seismometers’ parameters and station base noise of stations were obtained, the observational ability of stations were known well. That can offer a proposal for Jilin Seismic Network to improve observational ability.
