绥芬河基准站是黑龙江省地震烈度速报与预警工程新建基准站，配备GL-CS60B型井下地震计进行地震观测，为验证该地震计观测性能，以GL-CS60型地表地震计作为参考，进行方位角检验和标定计算，并对比分析2套地震计台基背景噪声水平，结果发现：井下地震计各项参数达到标准，其中方位角为164.349°。井下地震计抗干扰能力较强，尤其对于1—20 Hz频段的人为干扰压制作用明显，其台基背景噪声水平达Ⅰ级，观测数据质量更佳。
Suifenhe Reference Station is a newly built reference station in Heilongjiang Province earthquake intensity quick reporting and early warning project, which is equipped with a GL-CS60B underground seismometer for seismic observation. In order to verify the observation performance of the seismometer, a GL-CS60 seismometer at the surface is used as a reference to conduct azimuth inspection and calibration calculation and compare and analyze the background noise level of the two seismometers. The results show that the parameters of the underground seismometer are up to standard, and the azimuth is 164.349°. The underground seismometer has strong anti-interference ability, especially for the suppression of human interference in the 1-20 Hz band, and the background noise level of the station reaches levelⅠ, and the observation data quality is better.
