| 摘 要： | 通过对五指山台DSQ水管倾斜仪和VP垂直摆的观测数据统计，精度内在质量以及同震形变波分析，认为连续率、漂移量、内精度资料质量指标均符合形变要求规范。水管倾斜仪和VP垂直摆对不同震中距的地震记录存在较大差异:①当震中距较小时，水管仪无同震响应，VP垂直摆同震记录清晰；②当震中距＞6000 km时，两种仪器记录能力相当。

| Abstract: | Based on the statistical data, change trend analysis, accuracy, and co-seismic deformation wave analysis of DSQ water pipe inclinometer and VP vertical pendulum of Wuzhishan Station, it is considered that the quality index of continuity, drift, and internal accuracy data meet the requirements of deformation observation. The water pipe inclinometer and the VP vertical pendulum have great differences in the seismic records of different epicenter distances: ① When the epicenter distance is small, the water pipe instrument has no co-seismic response, and the VP vertical pendulum has the clear co-seismic record; ② When the epicenter distance is greater than 6000 km, the two instruments have a similar recording capability. |
