1979年8、9月间,我们在广东省饶平县钱东公社仙洲大队晒谷场上(23°39′20″N,116°55′20″E)设站进行地磁场的日变观测。 一、野外工作情况 站点在第四纪滨浅海沉积层上,下伏下侏罗统。磁场比较稳定,梯度变化极小,在360°范围内,除个别方位外,磁场总强度T的水平梯度均<0.6Υ/米,垂直梯度为0.7Υ/米。 出发前曾对各台备用仪器进行了全面检验,结果表明,各种性能良好。工作结束后,又进行了检查,证实仪器良好,工作正常。
In August and September 1979, we set up a station to conduct daily observation of the geomagnetic field in the Sun Valley Farm at 23 ° 39’20 “N, 116 ° 55’20” E in the Xianzhou Battalion, Qian Dong Commune, Raoping County, Guangdong Province . First, the field work Site in the Quaternary shore shallow sediments, the underlying Lower Jurassic. The magnetic field is relatively stable, and the gradient changes very little. The horizontal gradient of the total magnetic field strength T is less than 0.6 Y / m and the vertical gradient is 0.7 Y / m except for a few azimuths within 360 °. Before departure had a comprehensive test of each spare instrument, the results show that a variety of good performance. After the work was over, another inspection was carried out to confirm that the instrument was good and working normally.
