摘　　要：以甚宽频地震计BBVS120为研究对象,通过温度实验测试,研究温度对甚宽频地震计性能影响。结合分析关键元件材料的温度特性,讨论温度对甚宽频地震计灵敏度、幅频特性影响的原因,科学评价观测仪器的温度效应。The influence of temperature on the accurate measuring instruments and seismic observation instrument is ubiquitous and cannot be ignored. In this paper, we take the very broad- band seismometer BBVS120 as the object of study. Through analysis of the experimental data, we study the influence of temperature on the performance of broadband seismometer. With the analysis of the temperature characteristic of the key elementsr material, we discussed the reasons of temperaturers effect on the very broadband seismometerrs sensitivity and amplitude-frequency characteristic. Thereby we could give a scientific evaluation of observation instrument.
