The fist experiment studies the perception characteristics and ability of sound loction in horizontal plane and median plane.

Study of the intersection of surface normal with tool swept volume in accuracy verification of impeller surface machining;

The intersection of sweep volume with complicated surface normal is transformed into computation of intersection between triangular mesh and directed line segment.

Finite Element Bio-Contact Analysis of a Sagittal Knee Joint;

Localization Study of Gyri by Medullary Branches on Sagittal Section and MRI Image;

Objective: Localizing pre- and postcentral gyri on sagittal sections by medullary processes.

The sagittal sections of the cerebral specimens were compared with the MR images to study the localization of the central sul.

Based on the analysis of the luminous characteristics of typical lasers and optical properties of cylindrical lenses,a novel optical system for laser panoramic fuse,which uses two sets of cylindrical lenses with orthogonal sagittal planes to improve the scattering angle of laser beam and uses four sectors to realize the panoramic function,is proposed in this paper.
