本文主要讨论观测仪器的质量问题,着重讨论影响初动的有关仪器部件和它们的参数.提出用升起时间 t_s 作为评价仪器记录初至波质量好坏的特性参数.给出升起时间 t_s 和仪器频带之间的关系.对我国地震台站上常用地震仪器的升起时间作了比较.
This article mainly discusses the quality problems of observing instruments and focuses on the components of the instruments and their parameters that affect the initial move.The rising time t_s is taken as the characteristic parameter to record the quality of the first arrivals from the evaluation instrument.The rising time t_s and The relationship between the instrument band and the rising time of the commonly used seismic instruments on the seismic stations in our country are compared.
