TRANSIENT RESPONSE OF SEISMOGRAPHS

  • 摘要: 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ts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ts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.

     

    Abstract: The purpose of this paper is to discuss the quality of seismological recording instruments, especially to examine some instrumental components and their parameters that may influence the character of the first motion. We suggest to use the rise time ts as a parameter to characterize the recording quality of the first motion. A relation between the rise time and the frequency baud of the instrument has been obtained. The rise times of a number of seismographs installed at our seismographical stations in China are compared.
