摘　　要：针对垂直摆标定格值普遍存在超限问题,分析其原因主要是标定数据的选取不合适,没有消除标定电压差值中的潮汐变化量,本文通过推导、计算,介绍一种新的标定数据选取方法,该方法能够剔除潮汐变化量和一些高频的干扰变化,并编写了标定数据处理和格值计算程序,该计算方法已经得到了武汉地震研究所胡国庆教授的认可。目前,在张家口台、怀来台、阳原台、赤城台投入使用,达到了预期效果,提高了标定格值精度。There is generally an exceedance problem in the calibration for vertical pendulum tiltmeter. The main reason to the problem is that the calibration value we choose is improper, in which the tidal variation in calibration voltage is not eliminated. Here a new method to choose the calibration value is presented. This method can eliminate the tidal variation and high frequency interference, and is developed into program. After operation in Zhangjiakou, Huailai, Yangyuan and Chicheng Seismostation, the program reached the expectation in precision
