【摘要】 剖面法是表达地层形态的重要方法,它正向着计算机成图的方向发展,这一发展的关键是寻觅最适合的函数形式。 通过地质与数学方面的大量试验表明,三次样条函数的拟合效果最好。 本文对实验方法,函数的适应性作了说明,还利用拟合的结果对地层形态作了定量研究,最后对拟合误差作了估计,这将给勘探设计引入了定量的概念。更多还原

【Abstract】 Profile method is important with regard to the description of the Shape of a stratum.In developing Computer Cartography, the key is to find a functional form with optimal adaptation.Through a great deal of experiments involving geology and mathematics, we found that using the cubic spline to deseribe the shape of profile folds has the best fit.In this paper we explain the experimental method and adaptiveness of a function. Besides, we make use of the fitting result to do quantitative is estimated, and that establishes a quantitative concept with respect to drowing up a plan of survey.更多还原
