一、概述消除地形起伏的影响是山区重力勘探的资料整理中最繁重的工作。随着电子计算机的广泛应用,传统的手算方法将很快被电算所代替。目前,已有多种大比例尺、规则测网的重力地改电算方案问世,对小比例尺不规则网的重力地改电算方法也正在纷纷的试验中。我队结合1/(10万)的重力找盐工作,边生产边探索不规则测网的地改电算方案,七七年底初步试验成功。对43个重力点进行了地改电算,地改范围算至30公里,与手算对比的均方差为±0.15mgl,七八年,地改电算方法投入生产,共计算965个点,随机抽29
First, an overview Elimination of the impact of topography is the most important task of mountain gravity survey data collation. With the widespread use of electronic computers, the traditional hand calculation method will soon be replaced by the computer. At present, there are a variety of large-scale, regular measurement of the gravity network to change the calculation program come out on the small scale irregular network gravity to change the calculation method is also being tested. Our team combined with 1 / (100000) of gravity to find salt work, while the production side to explore the irregular network measurement of the conversion program, preliminary test success at the end of. The 43 gravitational points for the calculation of land conversion, land reform to calculate the range of 30 km, compared with the manual calculation of the mean square deviation ± 0.15mgl, 78 years, land conversion method into production, a total of 965 points, Choose 29 randomly
