摘　　要：对用水管仪与水平摆仪记录到的同一地震所激发的地倾斜响应进行对比分析,结果表明:水管仪与水平摆仪这两种观测系统对远震、近震及地方震都具有不同程度的同震响应;对于同一地震,一般水平摆倾斜仪的响应幅度大于水管倾斜仪;同一观测系统的响应幅度与震级成正比,震荡时间与震中距、震级有关。Comparative analyzing co-seismic response of water-tube and horizontal pendulum tiltmeters at Yunlong Seismic Station in Yunnan,the results show that both of the water-tube tiltmeter and horizontal pendulum tiltmeter have different degree of co-seismic response to distant,near and local shocks.Usually,the response amplitude recorded by horizontal pendulum tiltmeter is larger than that of water-tube tiltmeter for the same earthquake.And for the same observation system,the response amplitude is proportion to the magnitude of earthquake,and the oscillation time is relevant to epicentral distance and magnitude.
