摘要
为获得日本油壶和弥彦两个地壳运动观测所的北南、东西方位的地倾斜值，有学者曾简单地运用向量合成、分解中的＂平行四边形法则＂对两地的水管倾斜仪观测资料进行处理。这一处理方法不甚适合地倾斜观测的实情。按精确的计算方法对油壶（１９４９～１９８１年）、弥彦（１９６７～１９８３年）观测资料重新进行处理，所得结果与以前的处理结果相比有很大差异。并对地倾斜计算公式的精度进行了讨论。
The watertube tiltmeters settled at the Aburatsubo Crustal Movement Obserbvatory in Japan are composed of components N22°E and E9°S, their length are 25m and 10m respectively.The angle between both components is 77°. At the Yahiko Crustal Movement Observatory, two tiltmeters with the length of 30m are arranged to be orthogonal even though they deviate clockwisely from the normal N and E in an angle of 28°.In some papers, the observations were processed according to the parallelogram law but the results are unpractical.In this paper, the data are reprocessed by use of exact method. By comparing the results with each other It is found out that they are different. In addition, accuracy of the formulae for ground tilt data processing are also discussed.
