重力地形改正值的计算,是山区重力勘探中一项非常繁重的工作。为了减轻此项劳动,我国重力工作者多年来进行了很多试验研究工作,先后编制了DJS-103、121、108机手编程序供使用。近几年来在地质部门中广泛的推广了ALGOL算法语言。但是计算重力地形改正值还没有相应的语言程序,给及时利用电子计算机处理重力资料带来了一定困难。为此,我们在认真学习了各种手编程序的优点,并在近区数学模型的选择、中区数学公式的处理及远区参数的插值方法上做了某些改进后,编写了DJS-108机和M—160Ⅱ机的计算
The calculation of gravity correction data is a very heavy task in mountainous gravity exploration. In order to alleviate this kind of labor, our country’s gravity workers have carried out many experiments and research work over the years, and have successively compiled and compiled DJS-103, 121 and 108 hand-knitting programs for use. The ALGOL algorithm language has been widely promoted in the geology sector in recent years. However, there is no corresponding language program for calculating gravity correction data, which brings some difficulties to the timely use of computer to process gravity data. To this end, we have carefully studied the advantages of various hand-knitting programs and made some improvements in the selection of near-area mathematical models, the processing of mathematical equations in the middle area, and the interpolation of far-field parameters. We compiled the DJS- 108 machines and M-160 Ⅱ machine calculation
