摘　　要：为解决FGM01型磁通门磁力仪替换GM4-XL型后,存在模拟装置置于野外温度过高的问题,在运行这2种型号进行并行观测的江油台和巴中台开展了对比实验。实验将FGM01型的模拟装置置于仪器罩顶部来改善工作温度环境,计算并行观测的2个测点间3个分量数据的实验前后的皮尔逊相关系数来评估数据一致性。实验结果证明将FGMO1型的模拟装置置于仪器罩顶部,不会对其磁探头记录数据有显著影响。并且巴中台的测点3和南山台调整模拟装置位置后,模拟装置的工作环境温度明显改善,有助于延长设备的工作寿命。针对只有单个安装仓的地埋式地磁观测台站,可以采用上述做法处理。To address the issue of excessively high outdoor temperatures affecting the simulation device of the FGM01 fluxgate magnetometer after replacing the GM4-XL model,comparative experiments were conducted at the Jiangyou and Bazhong stations,where these two models are run in parallel observation.In the experiment,the simulation device of the FGM01 model was placed on top of the instrument cover to improve its operating temperature environment.The Pearson correlation coefficient between the data of the three components from the two measurement points before and after the experiment was calculated to evaluate data consistency.The experimental results demonstrated that placing the simulation device of the FGM01 model on top of the instrument cover does not significantly affect the data recorded by its magnetometer.Furthermore,after adjusting the position of the simulation device at Bazhong Station's measurement point 3 and Nanshan Station,the working environment temperature of the simulation device was significantly improved,which helps extend the equipment's working life.For buried geomagnetic observation stations with only a single installation chamber,tohe above approach can be adopted.
