南通台核旋观测干扰的排除

针对南通地震台核旋观测的干扰 ,通过多种试验最终加以排除。这项工作表明 ,地震台站环境改造中要注意监测环境的保护 ,特别是铠装电缆的铺设要考虑到对磁、电观测的影响 ,并就如何进一步提高核旋的观测质量提出建议。

Elimination of disturbances in nuclear precession geomagnetic observations at Nantong Seismic Station

In the present paper a brief outline has been given on how the disturbances in the nuclear precession geomagnetic observations at Nantong Seismic Station have been eliminated after a number of experiments This work has shown that much attention should be paid to the protection of the observational environment in the work of improving the environment of a seismic station,especially to the influences of the laying of an armored cable to the geomagnetic and electric observations Some suggestions have been made on how the quality of the nuclear precession geomagnetic observations can be enhanced
