摘　　要：文章讨论由有理混合基函数构造的RBF-Coons曲面片,是双三次Coons曲面片的推广,它的形状调整依赖于参数λ1,λ2,调整参数λ1,λ2的值可以改变曲面的内部形状.特别当形状参数取0时,可得到优化的混合函数.Disscuss RBF- Coons surface which is constructed by the rational blending function, and it is the evolution of bicubic Coons patch, and its shape can be modified by parameters. We can also change the internal shape of the surface by adjusting the parameters. In particular, when the shape - parameter is 0, the blending function will be optimized.
