| 摘 要： | 我国境内几次中强震及山西地区6次有感地震前，临汾地震台两种摆式倾斜仪存在有不同反映，探讨不同摆式倾斜仪对同一地震监测能力的差异性和同一仪器对不同地震的异常反映能力，结果表明：①摆式倾斜仪监测震兆信息的距离范围由仪器自身的监测能力（综合噪声水平及观测精度）和未来震级的大小所决定；②对于不同地震，两摆式倾斜仪所表现出的异常形态不同，即便在同一观测仪器上表现出来的异常形态也存在差异；同一地震两摆式倾斜仪所反映的异常并非呈相关一致性，而且同一仪器的不同方向对异常信息的捕捉能力也存在明显差异。

| Abstract: | Before several times middle and strong earthquakes in China and six sensible earthquakes in Shanxi region, two pendulum type tiltmeter has different reflection at Linfen Seismic Station. In this paper, the different pendulum tiltmeter for the same earthquake monitoring ability difference and the same instrument in different earthquake anomaly reflection ability are discussed. The results are as follows ： ①The range of monitoring earthquake precursor information of the pendulum type tiltmeter by instrument with their ability to monitor （integrated noise level and the observation precision） and future earthquake magnitude determined. ②For different earthquake, it is different to exhibited abnormal morphology of two pendulum tiltmeter, even in the same observation instruments exhibited abnormal morphology is different; For same earthquake, reflects abnormal morphology of two pendulum tiltmeter do not show coincident variation, but capturing ability of anomalous in the different directions of the same instrument also exists obvious difference. |
