摘　　要：在对江苏数字前兆观测资料分类的基础上,对其中的干扰及其特征和机理进行了初步描述,发现地电阻率观测值在远大震前的前驱波变化、自流热水井水位与地热同震效应的同步变化值得今后进一步深入研究;FHD磁力仪分量观测转向差的长期漂移,可避免今后应用该仪器观测资料时出现缪误。另外,苏16井井口脱气装置的改造对今后数字水化学观测改造有一定的借鉴作用。Bosed on classified the data of the digital earthquake precursor of Jiangsu,this paper described the characteristics and mechanism of interference among them.We discovered that the changes of the precursor wave of earth-resistivity before the distant-strong earthquake, the synchronous changes about the water level and the geothermal synchronous earthquake effect of the hot self-flowing well are valuable to be studied. The long period drift of the directional error of FHD vector proton precession magnetometer can avoid errors when using its data. In addition, the rebuilding of the gas-water separation device of Jiangsu No.16 well is use for reference to reform of digital hydrogeochemistry observation in the future.
