| 摘 要： | SSQ-2I型水平摆仪器和DSQ水管仪同属倾斜类前兆仪器,两者观测原理不同,但观测物理量一致.相对于水管仪而言,SSQ-2I型水平摆属于新型仪器,有关其运行效能的评价很少.延庆地震台从2007年开始两种仪器同场地观测,通过年变幅度、滤波残差、周期分析、Venedikov调和分析、相关性分析、抗干扰能力等角度,对两种仪器... |

| Abstract: | DSQ water tube tiltmeter and SSQ-2I horizontal pendulum belong to the tiltmeter equipment, which observe the same physical quantity hut with different principles. Because SSQ- 2I horizontal pendulum is the new type instrument comparing to the water tube tiltmeter, the evaluation of its running efficiency are few. In this article, the comparative study and evaluation on the annual variation amplitude, filtering residuals, period analysis, venedikov harmonic analysis, correlativity analysis, anti jamming ability and efficiency of DSQ water tube tiltmeter and SSQ-2I horizontal pendulum at Yanqing Seismic Station are carried out. |
| Keywords: | DSQ water tube tiltmeter SSQ-2I quarts horizontal pendulum tiltmeter efficiency |
