摘要
从传统的重力地形改正方法入手,用Delphi语言编制了Windows程序,使得多年来重力中区地形改正繁重的手工数图工作能够用计算机完成,且计算精度得到明显提高。最后用甘肃1∶20万昌马幅的53个重力测点进行了试算。
Starting with the traditional gravity topographic correction technique, the author completed Windows programming by using Delphi language, thus making it possible for computer to perform the gravity intermediate area topographic correction which had to be completed by manual calculation in the past and hence evidently raising the calculation precision. 53 gravity measuring points in 1∶200 000 Changma sheet of Gansu Province were used to perform tentative calculation.
