By means of the method of local surface fitting, the ordered data points on section plane are obtained.

采用局部曲面拟合方式得到位于截平面上的有序数据，使得无序的散乱数据形成了有序的阵列数据，实现了NURBS曲面的精确拟合。

This kind of G〓 smooth surfaces consisting of rectangular and triangular Bézier patches interpolates to the given data and inherits the topology imposed by the rectangular partition and triangulation.

第二章和第三章系统地归纳总结了现有曲线、曲面几何连续性的各种等价定义及其应用，并详细讨论了构造具有几何连续的Bézier样条曲线、曲面方法。

In this study, two models to fit soil three-variable characteristic surfaces of different soils were proposed based on the Brooks-Corey soil water retention curve model. Advantages, disadvantages and application conditions of the two were illuminated. In addition, soil three-variable surfaces measured for packed soil samples through centrifuging and controlling bulk density using paraffin material were used to verify the proposed models.
