The algorithm is applied in the segmentation of Magnetic Resonance Imaging of human brain for the 3D reconstruction on dependent of different human tissue structures, in which the problem on wraps between different tissues and fuzzy edges between the different regions in medical volume data may better be settled, which can not be well done by the typical"hard"segmentation using binary logical representation.(3) An accelerated algorithm of volume rendering with X-ray perspective and Phong shading effect based on textures mapping and blending is presented for realizing 3D reconstruction of medical volume data by 2D texture mapping and blending, in which the accelerated algorithm of window transformation is utilized to computing voxels' gray scales and opacities to produce X-ray perspective images, and Phone illumination model is used to import world light sources and an unit spherical surface under the same shading environment as the actual volume rendering is employed to simulate the real reflectional light of per-voxel so that 3D reconstruction possesses illumination effect in the world. Furthermore, 3D matrix transformations of degree rotation and other operations of 3D object are studied, and a fast equivalent method of corresponding shading correction is brought forward to improve its interaction speed in volume rendering process.

为了更好地了解用户使用中文进行数据库查询的句式以及从中抽取一定的语法规则，我们进行了用户使用受限汉语书写数据库查询语句的调查和分析，然后在此基础上我们设计了一种新的文法GWERSC，其非终结符集合不仅采用了现代汉语的文法符号，如名词短语、助词等，同时还采用了与数据库概念紧密相关的实体、属性、联系等语义符号，这样就把现代汉语尤其是受限汉语的知识和数据库知识紧密结合起来，既有利于文法分析又简化了语义处理。

The infrared image has blur edges and many noise points. Traditional methods need to calculate the grads, so they are sensitive to unregular details and noises. When the contrast is low, departure may appear for extracted transition region, thus will affect the judgement of segmentation threshold value and the segmentation result.
