However, the reason that LCD can't fully take the place of the tube is mainly on the performance of color and motion image. Though LCD can greatly improve the Color Saturation up to NTSC 105%, LCD is limited on reaction time and continue LCD light source, which create image shape shadows while the image moves due to photogene.

而液晶显示器目前无法完全取代映像管的地方就在於色彩及动态影像的表现，虽然发光二极体已可大大改善色彩饱和度到达NTSC 105%，但液晶显示器受限於液晶的反应时间及液晶显示光源表现为持续方式，使在动态影像表现上因人眼的视觉停留的因素导致影像移动的边界上产生阴影。

While Andalusite's color play has been compared to Alexandrite, this is technically incorrect as pleochroic (displaying different colors in different directions) gemstones like Andalusite feature all their colors at once, whereas Alexandrite only changes color in different light sources.

把红柱石的颜色变幻与亚历山大石相比，从专业角度来讲，这种比较并非科学，因为如红柱石一类的多向色性（不同方向呈现不同的颜色）宝石会在瞬间显现出她所有的颜色，而亚历山大石是靠不同的光源进行着颜色的变化。

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.
