Two above methods are generalized to tensor product Bézier surfaces and triangular Bézier surfaces, we give two approaches of degree reduction for tensor product Bézier surfaces, each of which reduces a given degree n×m tensor product Bézier surface to a n〓×m〓 one, and two methods of degree reduction for triangular Bézier surfaces, which reduce a given degree n triangular Bézier surface to a degree m one. The explicit formulas of control points for reduced tensor product and triangular Bézier surfaces are obtained respectively.

Surface water was sampled at the three red tide stations during the Guinardia delicatula bloom in Jiaozhou Bay on February 9-10, 2004 and the colloidal substances were separated by filtration(0.7μm)and cross-flow ultrafiltration (1000 Daltons). The organic carbon in the filtrates and retentates were analyzed respectively. Heterosigma akashiwo and Skeletonema costatum were cultured in the 000Daltons ultrafiltrate and the retentates with different amount of colloidal substances (1000 Daltons-0.7μm).
