摘要： The invention discloses a La(Fe,Si)13-based hydride magnetic refrigeration material comprising multiple interstitial atoms and showing a high-temperature stability and a large magnetic entropy change and the method for preparing the same. By reintroducing interstitial hydrogen atoms into an interstitial master alloy La1-aRaFe13-bSibXc through a hydrogen absorption process, a compound with a chemical formula of La1-aRaFe13-bSibXcHd and a cubic NaZn13-type structure is prepared, wherein R is one or a combination of more than one rare-earth element, X is one or more C, B and the like or their combinations. A desired amount of hydrogen is obtained through a single hydrogen absorption process by means of controlling the hydrogen pressure, temperature and period in the process of hydrogen absorption. The compound can be stable under normal pressure, at a temperature of room temperature to 350° C., that is, the hydrogen atoms can still exist stably in the interstices. The Curie temperature of the compound can be adjusted continuously with a wide range of 180K to 360K by changing its composition. The magnetic entropy change that is more than 2 folds of that of Gd can be obtained around room temperature, and the magnetic hysteresis loss vanishes. In view of the above, this material is a desired magnetic refrigeration material applied at room temperature.

摘要： A method of displacing a tessellated surface, based on features of a displacement map, by analyzing a model to determine the level of detail in the model. Where the level of detail is high the number of polygons, typically triangles, used to represent the high detail area is increased through the use of “sub-triangles”. The positions of the sub-triangles are also strategically located and constrained to better represent the high detail area, particularly any edges in the area. The level of detail can be determined using a displacement map for the surface. The positions of the triangles can be located by determining feature points (or sub-triangle vertices) in the areas of detail where the feature points can be moved toward the areas of high rate of change and additional feature points can be added. The feature points can be connected to form the sub-triangles with an emphasis or constraint on connecting points along an edge or border.
