针对陕西省乾陵地震台FHD分量质子磁力仪和CB-3型三分向磁变仪的记录资料 ，利用线性相关性分析法,求出这两种仪器记录曲线的相关系数及剩余离散程度,定量分析其记录资料的相似程度，查看是否满足地震预报工作对资料连续性的要求。研究认为，两台仪器的观测数据一致性较高，两种资料延续衔接使用的可能性比较高。

Based on data recorded by FHD component proton magnetometer and CB3 threecomponent variometer at Qianling Seismic Station in Shaanxi Province, the related degree coefficient and residual discrete degree for curves recorded by the two instruments are obtained with the correlativity analysis method in probability theory. Examination of quantitative analysis could therefore be done on aspects as similarity degree of the recorded data, whether these data can meet the requirements of material continuity in earthquake prediction, and information generality. Observation data of the two instruments uniform with each other greatly and are of relatively high possibility of continuous and cohesive application.
