摘要： An artificial acetabulum having a multilayer shell-core composite structure includes a ceramic acetabular liner, a transition layer and an acetabular shell. The acetabular shell is made of a porous metal, a porous alloy or a porous toughened ceramic; the ceramic acetabular liner is made of a ceramic material; and the transition layer is made of a composite material comprising materials of the acetabular shell and the ceramic acetabular liner. The artificial acetabulum is manufactured through sintering a green body of successively stacked layers of the ceramic acetabular liner, the transition layer and the acetabular shell, and the green body of successively stacked layers is obtained through a powder co-injection molding process. The ceramic acetabular liner of the artificial acetabulum has a high rigidness, corrosion-proof and wear-proof performance. The acetabular shell of the artificial acetabulum has a high toughness and shock resistant performance.

摘要： A laser beam having a Mathieu-Gaussian intensity profile is provided, which may be used for various optical scanning applications at various scanning distances. The Mathieu-Gaussian beam exhibits a zone of illumination characterized by a central spot and side lobes centered on an axis of elongation of the zone of illumination. The zone of illumination may be used with scanners that either generate a single scan line, or another omni- or multi-directional raster pattern, to scan symbols over large variations of distance.
