In order to realize the accurate deformation of the parametric surface, a special vector extension function was established to realize the interpolation deformation for parametric surface, in the course of the deformation.

In the full paper we explain in detail our method of constructing affine transform matrix with bivariate B-spline extension function for facilitating deformation of parametric surfaces;in this abstract we just give a briefing.

Considering the teaching need of higher mathematics in colleges,the unified definitions of vector functional integration are given.

An interpolating formula and estimation for approaching calculation of a 3D disturbed curve in a vector field on basis of a vector function interpolating was presented,and its convergence was proven,some of which can be also applied in such fields as coloring algorithm of fractal,visual components and computer tomography graphics,3D computer terrain interpolating and rendering.

Scalable Vector Graphics(SVG),a thin-client technology,is the focus of current researches,which represents the new technical generation and provides many advantages compared to the raster-based presentation and extensibility through other Web programming languages.

Using this method can be constructed based on svg vector GIS.

For engineering configuration,a SCADA graph-database configuration system is developed,which takes SVG as the graphic format and applies Batik package and Hibernate persistence framework.

Integrating the concepts and theories of CSCW with the idea of distributed processing, a three-hierarchized structure is established and concurrency control and SVG are discussed in detail.
