摘要
对地震计的传统标定方法作了简单回顾 ,提出了借助Matlab工具软件用单位阶跃信号精确快速测定地震计的周期和阻尼系数的方法 ,给出了具体的设计思路与程序和测量实例 ,并进行了误差分析。
The traditional seismograph calibration methods are reviewed briefly. A new method using step signal to test the seismograph's cycle and damping coefficient by Matlab tool is described. The design idea and program and example are presented and the error is analysed.
