最近发展了一种计算重力测量的地形校正的数位方法,这种方法通过一个单位西数仿效地形的近似.此方法避开了重力效应的体积分到二维有作积分的交换.利用高斯一勒让德求积公式,有限积分一部分是由显式积分求解,另一部分是由数位积分求解.这种方法非常适用于开其距测点50m到l000m的地形校正,特别在陡峭下降地区的微重力浏量.为了在实践中检验这个方法,我们在克班(土耳其东部)地势崎呕起伏的地区将其试用.
Recently a digital method of terrain correction for gravimetric measurements has been developed that approximates the topography by a single unit of the western count that avoids the exchange of volume fractions into two- Letde quadrature formula, the finite integral part of the solution is by explicit integral, the other part is solved by the number of integrals. This method is very suitable for its distance from the measuring point 50m to l000m topographic correction, especially in the steep decline of microgravity In order to test this method in practice, we tried it in the bumpy area of Kraban (eastern Turkey).
