| 摘 要： | 与VS型垂直摆各项参数进行对比，分析VP型宽频带垂直摆具有的优势。采用VS、VP型垂直摆记录资料，对比数据连续率、完整率及固体潮记录能力、同震变化等；分析VP型垂直摆精度、潮汐因子绝对误差、相位误差等，以偏离正常年变背景为基准，判断其数据记录是否异常，并分析年变特征，拟合观测数据分析异常特征，通过R值评分，进一步分析承德地震台VP型宽频带垂直摆映震能力。分析发现，VP型宽频带垂直摆记录固体潮和同震曲线的能力较好，精度较高，潮汐因子误差及绝对误差较小，产出数据更为可靠，异常信息更为明显，映震能力更高。

| Abstract: | Compared with the parameters of the VS vertical pendulum, the advantages of the VP wide band vertical pendulum are analyzed. The data of the VS type and the VP broadband vertical pendulum are compared in the aspects of recording ability, data continuity rate, integrity rate, solid tide recording ability, and coseismal variation, and so on. The precision of VP broadband vertical pendulum data, including the absolute error of tidal factor, phase error, and so on, are analyzed. On the basis of deviation about the background of the normal annual variation, the abnormal characteristics of the annual variation are analyzed by fitting the observation data. Through the R value score, the earthquake response capability of the VP broadband vertical pendulum is further analyzed. It is found that the VP broadband vertical pendulum had better coseismal response and the ability to record solid tide. Its data has high degree of accuracy with smaller tidal factor error and absolute error. And the data is more reliable. The abnormal information is more obvious, and the ability to reflect the earthquake is higher. |
