Using active fault movement data, we calculated the average horizontal strain rate field of China Continent and vicinity since late Pleistocene with Bessel bicubicspline model.
The input parametric surfaces are discrete, then we will get new surfaces with bicubic parameter spline function and build uniform workpiece model.
对于参数曲面，采用先离散，再重新拟合的处理方法，建立统一的双三次参数样条曲面通用工件模型。

The structure of mathematical vessel-model and the existence and uniqueness of the solution is studied and the procedure for computing Bicubic Smoothed-Spline Surface is also provided.
