摘要
通过对采样率不同的两套数字石英水平摆倾斜仪观测曲线进行对比分析,结果显示:秒采样获得的倾斜记录的分钟值与分钟采样获得的倾斜记录的潮汐波一致。采用秒采样观测能够获得大量丰富的信息,在同震响应中,能清晰记录到P波、S波。秒采样提高了地震响应能力。
Two record curve of digital quartz horizontal pendulum tilt meter observation with different sampling rates were comparatively analyzed. The results show that the tide wave revealed in two type records, second sampling and minute sampling, arc consistent. The second sampling observation contain more abundant information. At the coseismic response, the second sampling observations can clearly record P wave, S wave signales. The second sampling record can greatly improve the ability of earthquake response.
