中文摘要：
将船体曲面的NUImS表达与径向基函数插值技术相结合，实现了船体曲面的三维自动变形。重点阐述了径向基函数插值技术的基本原理及其应用于船体曲面变形的过程。最后，以国际标模KCS船为例完成了船艏、艉部曲面的自动变形。研究结果表明：基于径向基函数插值技术的船体曲面修改方法适用于船型优化，符合工程实际的需要。
英文摘要：
NURBS description of hull form is combined with interpolation technique of radial basis function, and three dimensional deformation of hull surface is implemented automatically. Fundamental principles about interpolation of radial basis function and its application in the hull form deformation is elaborated. Taking KCS standard model as an example, automatically global deformation of ship bow and stem surface is achieved. The result indicated that this method has practical engineering value and can be applied to hull form optimization.
