| 摘 要： | 三维趋势分析是地质学中一种有用的数学工具,但是空间分布的计算结果造成了分析上的困难。三维趋势分析的图形显示则弥补了这一方面的不足。本文提出了三维图形显示的原理和方法,并用 FORTRAN 语言编制了图形显示的程序。所得的图形具有充分的立体感。用户可由各种不同的角度显示结果,并可通过切片方法看到地质体内部的函数值变化。

| Abstract: | Three-dimensional trend analysis is an useful mathematical tool in geology. But the results of spatial distribution obtained in calculation are usually troublesome in analysis. The graphical display of three-dimensional trend analysis can overcome the shortcomings.The principle and method of three-dimensional display have been presented and a FORTRAN program has also been compiled for this purpose. The figure displayed has sufficient stereoscopic sense and the user can view it in any direction. The variation of the trend within a geological body can also be seen by cutting it into slices. |
