According to reality of artillery geodesy, the system makes use of the multi-measurements to improve the accuracy of geodesy.

The study of geodesic of three patterns in hyperbolic space;

On some properties of geodesic and totally geodesic submanifold in Finsler manifold;

Based on the geodesic,a novel parallel equidistant path generation algorithm for composite fiber placement was implemented.

Finally,the development from 3D surface to 2D planar counterpart based on the character of geodesic was realized.

Based on the geodesic curvature calculating method in differential geometry,a mathematical model for checking curvature interference between the major cutting edge and the cylindrical grinding wheel during grinding clearance face of a ball nose end milling cutter with S shaped major cutting edge is developed.

Since the curvature vector of a curve on a surface can be decomposed into normal curvature vector and geodesic curvature vector, a surface curve can be designed first on a plane and then mapped onto the surface.

Some geometric data of ellipse in hyperbolic space are considered,such as set inclusion,arc length,geodesic curvature,curvature,area and total curvature.

Field application of dot immunogold filtration assay in brucellosis surveillance area;

Because arc length of trajectory is regarded as the variant in geodesics based method,it .

Wang, on general Grassmann manifolds, some morespecific properties of geodesics in G_1 (S￣(n+1)) are obtained.

, the Ernst equation, and the generating technique of solutions, some spacetime properties and geodesics properties are studied by using the NUT-Taub-like (NT-like) solution obtained recently.
