高精度速度地震计工作周期和工作阻尼的精度研究

摘要

The target of the study on seismic observation system based on exact transfer function is to enhance the precision and stability of seismometer by a big margin , the precision of work period and work damp can be raised from percents in current to one ten-housandth , and to satisfied the urgent needs of accuracy data for eartnquake re-search and eartnquake prediction .This study has two apartments:to develop the highly precise velocity Seismome-ter and highly precise displacement Seismometer .At present , the experimental prototype of highly precise velocity seismometer has been finished , and had run it experiment at Anxian earthquake station .%精确传递函数地震观测系统的研究目标是大幅度提高地震观测的精度和稳定性，可将目前地震计的工作周期和工作阻尼从百分之几至百分之几十的精度提高到万分之一，为地震科研与预测预报提供更为准确可靠的数据。该研究分为两部分：高精度速度地震计原理样机研制和位移地震计原理样机研制。目前，速度地震计原理样机已研制完毕，并在安县地震台进行了试验测试。
