| 摘 要： | 通过对泉州地震台g-Phone重力仪自正式运行以来观测资料的干扰因素进行总结，发现数采死机对数据影响较小，但断电造成的仪器内部温度的改变会导致原始数据漂移，从而降低数据的内在质量，建议应尽量避免人为操作如断电等造成的内部温度变化；台风影响使得数据噪声变大，表现为观测曲线变粗，呈纺锤状。希望研究结果可以为进一步利用重力资料提取地震前兆信息提供一定的参考。

| Abstract: | This paper summed up the interference factors of Quanzhou seismic station g-phone gravimeter observation data. It is considered that the change of working state and the influence of meteorological factors are the main interference factors. The change of the internal temperature of the instrument has a great influence on the data, so it is necessary to avoid the change of the internal temperature caused by manual operation such as power failure. The rainfall and the change of air pressure caused by typhoons increased the noise of the data. |
