摘要
本文简要叙述了Ｂ－Ｓｐｌｉｎｅ样条函数的基本性质；将二元高阶Ｂ－Ｓｐｌｉｎｅ函数与Gａｌｅｒｋｉｎ方法相结合，形成了任意光滑空间曲面的二元高阶 Ｂ－ Ｓｐｌｉｎｅ函数簇解析表达方法； 讨论了 Ｂ－ Ｓｐｌｉｎｅ函数在三维水弹性力学边界积分方程中应用的一些数值计算问题。
In this paper a brief description of B-Spline function is introduced, and use of B-Spline conbined with the Galerkin method to represent analytically an arbitrary smooth surface has been carried out. The numerical approaches for applying the B-Spline method to the boundary integral equations in the three-dimensional hydroelasticity have been discussed also.
