| 摘 要： | 本文针对我国地倾斜观测仪器设置的实情，推导出由任意两方向设置的倾斜仪观测资料计算地倾斜角及其倾斜方位角有的通用公式，以及归算至南北、东西方位的公式。用本文的公式对泰安台两种类型倾斜仪观测进行了归算，归算后其倾斜固体潮曲线同就变化，相关性明显增强。对大同－阳讥Ｍｓ－６．１地震前的倾斜异常资料也进行了归算，归算后异常也比较明显。最后，作用还对我国地倾斜观测资料的归算工作提出了具体意见。

| Abstract: | In this paper,in view of the actual situation of setting ground tiltmeters in our country,wehave derived the current formulae which are used to calcutate the ground tilt azimuth and thedip angle by using observations of the tiltmeters installed in two arbitrary directions and theformula which is used to reduce the data to NS and EW directions.For two kinds of tiltmetersof Taian station,the curves of ground tilt tide have presented synchronous changes after thedata have been reduced by using the formulae,and the correlativity have increased obviously. Also,the great changes have taken place after the tilt anomaly data before the Datong-Yang-gao Ms=6.1 earthquake have been reduced,In the end of this paper,the concrete opinionsabout the reduction of ground tilt observations are given. |
