The research of Fraunhofer diffraction from the ellipsoid model;

The surface charge density and electric field strength of charged ellipsoid conductor;

The criteria of conflict overlap of any two ellipsoidal aggregates are proposed based on a volume-index, and a numerical method of three-dimensional random aggregate model is realized.

The variation of the 3-dimensional structures of flow separation with Reynolds number for a prolate spheroid;

Investigation of separate flow around a prolate spheroid in laminar and turbulent flow by an improved oil-flow visualization technique;

Discussion on NC Turing method of the ellipsoid surface;

And it pur forward a new type of computing on the ellipsoid surface or deviating from the ellipsoid surface.

This digital terrain model (DTM) based on the ellipsoidal surface is essentially different from DTM based on projected plane because the Delaunay triangulation net is built based on geodesic coordinate system on regional ellipsoidal surface.

In order to overcome the crack,imprecision of geographic analysis and data redundancy caused by the traditional digital elevation model in modeling the large scale terrain, this paper presents a method of global digital elevation modeling based on hierarchical subdivision of the quaternary triangular mesh on ellipsoidal surface.
