摘　　要：文章研究了康斯插值的基本理论，给出了构造康斯插值曲面的一般方法，对布尔和逼近与误差估计也作了探讨；最后，用双三次康斯曲面拟合１／８椭球面。理论和实践都证明，该方法精度高、效果好。In this paper, the fundamental theory of coons interpolation is studied, and the general method to construct coons interpolation surface presented. At the same time, the Boole sum approximation and its error estimates are also discussed. Finally, the authors use bicubic coons surface fitting 1/8 ellipsoid. This method has been proved to be highly accurate and efficient not only in theory but also in practice.
