【Abstract】 With consideration given to the application method of Gaussian curvature computation formula to curved surface,a technique is suggested for solving Gaussian curvature of ellipsoids.By using curved surface coordinate grid of the orthogonal curve,the proving process of Gauss-Bonnet formula is shown and the source of a simplified Gaussian curvature formula is also pointed out.From the surface integral results of Gaussian curvature,some geometrical meanings are derived for surface integral.更多还原
