为红山地磁台绝对观测仪器DI仪配备防尘防潮罩,为避免照明灯泡金属螺旋帽磁性对绝对观测数据造成影响,对灯泡进行人工改造。两项技术简单、实用,为产出高质量的数据提供保障,值得在全国基准地磁台站推广应用。
For Hongshan magnetic station absolute observation instrument DI instrument is equipped with dustproof damp proof cover, in order to avoid lighting bulb metal screw cap magnetic absolute impact on the observed data, the light bulb artificial transformation. The two technologies are simple and practical and provide a guarantee for the production of high quality data that is worth popularizing and applying in the national benchmark geomagnetic station.
