摘　　要：文章通过引入多个形状参数,给出了Wang-said广义型Ball曲线的扩展,该类曲线的基函数是显式表示的,易于求导和求积;通过改变形状参数的值,可以局部或整体调控曲线的形状,同时给出了带多形状参数的Said-Ball曲线。In this paper the extension of Wang-Said type generalized curves is provided by introducing some shape parameters. The blending functions of these new curves are showed explicitly, therefore they are easy to be integrated and find their derivative. By changing the values of those shape parameters, the shape of these new curves can be adjusted locally or entirely, and Said-Ball curves with multiple shape parameters are provided in the paper.
