摘　　要：DSQ型水管倾斜仪与VS型垂直摆倾斜仪观测的物理量均为地倾斜,然而两套仪器的观测原理不同。本文从同震响应最大响应幅值、延迟时间和持续响应时间3个方面,对赣州地震中心站DSQ型水管仪与VS型垂直摆记录到的同一次地震的地倾斜响应进行对比分析,结果表明:①两种倾斜仪器同震响应持续响应时间与震级大小有一定的正相关性;②两套仪器地震响应延迟时间与震中距呈一定的正相关性;③由于仪器设计和观测原理不同,使得记录到的同震响应信号有所差异。Using the co-seismic response data from the DSQ water-tube tiltmeter and the VS vertical pendulum tiltmeter at the Ganzhou seismic center station in Jiangxi,we analyze the maximum response amplitude,the delay time and the continuous response time of the two instruments.The results show that:①There is a positive correlation between the continuous response time and magnitude;②There is a positive correlation between the delay time and epicenter distance;③Because of the differences of instruments design and observation principle,the recorded co-seismic response signals are different.
