| 摘 要： | 介绍了一种适合于非网格休样品点研究区域的插值方法－多重二次曲面函数插值法。这种方法运用二次基本曲面函数作为插值的基函数，数学方法简单，易于编程实现。该方法对原始数据的边界和分布情况要求不高，适合于处理分散的和非网格化的数据。将该方法引入煤层地质曲面逼近，效果良好。

| Abstract: | A new method of mutiple quadric interpolation suitable for the non gridded research field was introduced. With the quadric surface function being the basic function of interpolation, the method is simple in mathematics, easy in programming, and good in approximation effect when it is used to fit the geological surface. In addition, this method has only a few requirements for the boundary conditions and distributions of the original data. |
