【Abstract】 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 broadband 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 elements material,we discussed the reasons of temperature s effect on the very broadband seismometer s sensitivity and amplitude-frequency characteristic.Thereby we could give a scientific evaluation of observation instrument.更多还原
