摘要
目前在计算地倾斜倾角和方位角时,一般文献仅给出了两个水平摆成直角组合的计算公式,而这种特殊组合方式并不能代表两摆成任意夹角的组合情况。本文给出了适用于任意组合的通用公式,证明了前者仅是后者的一种特例,并对各种组合特性及其精度进行了讨论。
In order to calculate tilt and azimuth of earth surface, the calculation formulae which are applicable only to orthogonal combination of two pendulums are given in many references. In This paper, the formulae which are applicable to arbitrary Combination of two pendulums are given, in addition, the characters and error of different combination axe discussed.
