红山地磁台绝对观测室部分技术改造

摘要

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。%The special covers are designed for dust and moisture prevention and lighting bulbs are modified to avoid the metal screw of the light influencing on the absolute magnetic observa-tions.The two maintenances are simple and convenient.They are worth applying in the geo-magnetic observatory for high quality data.
