Research and Experiments on JCZ-360 Ultra Broadband Seismometer
介绍了 JCZ系列超宽频带地震计JCZ-360的研究进展、定型测试、台站实验观测等情况.结果显示,JCZ-360超宽频带地震计能有效抑制外界大气压力、外部磁场干扰及温度变化对仪器的影响,性能更稳定,在超低频端噪声水平更低.JCZ-360超宽带地震计不仅可以观测到全频段地震波,还可以记录到固体潮汐、地球自由振荡等信息,具备传统地震和地球物理场的综合观测能力.
This paper introduces the research progress,standardized test and experimental observation on seismic station of the JCZ series ultra broadband seismometer JCZ-360.The results show that the JCZ-360 ultra broadband seismometer can effectively suppress the influence of external atmospheric pressure,external magnetic field interference and temperature change on the instrument.Its perform-ance is more stable and noise level is lower at the ultralow frequency terminal.The JCZ-360 ultra broadband seismometer can not only observe full-band seismic waves,but also record information such as solid tides and free oscillation of the Earth.It has the comprehensive observation ability of tradi-tional seismic and traditional geophysical field.
