So, used the MCAO model, electropuncturing Dazhui and both Neiguan to observe the effect of uPA and PAI-1, suggesting that will supply theoretical basis for clinical practice. Method: 40 SD rats were devided randomly into 4 groups as normal group, shamoperation group, model group and EA group.

Methods Cross-sectional images between the top layer of ethmoidal sinus and thebottom layer ofmaxillary sinus from the Chinese visible human data setwere reviewed on a section-by-sectionbasis. Three-dimensional computerized reconstruction of the sella turcica and its adjacent structureswere per-formed.

应用中国可视化人体数据集，选取从筛窦上缘到上颌窦下缘的连续断层图像，在计算机上对经鼻蝶入路重要结构的断层图像轮廓进行数据分割、对位重建和三维显示。

The algorithm smooths the gray histogram of the test image with Harr wavelet to remove the "pseudo valley", and fixes a range of the threshold according to the prior information in the standard image, and then finds out the valley of the histogram in the range and that is the threshold. The ex perimental results show that the preprocess algorithm is able to obtain a satisfactory threshold for the binarization of the test image.

该方法使用Harr小波对待测图像的灰度直方图进行平滑处理来消除其中的&伪谷值点&，再充分利用标准图像的先验信息来确定一个二值化分割阈值的大致范围，最后在这个范围内找到直方图的谷值，这即是所需的阈值。

Through a stretch-based mesh parameterization process, this paper finally achieves the homomorphous target mesh, which is then used to render the target image by texture mapping.

另外，该方法在参数化的过程中增加了对显著区域和背景结构的约束，能够在保持并增强图像中重要物体的同时，使适应图像的结构不发生明显形变。

Directly reading the 210-layer of 0.65-mm-thick consecutive CT Dicom format images of human body thoracolumbar making use of 0.625-mm isotropous resolution thin layer scanning technique into the Mimics. Defining bone organization threshold, withdrawing each outline, partitioning each edge of layer picture, edited selectively and repaired by hole processing. After a redundancy data was cleaned, the thoracolumbar 3-D finite element geometry model was acquired. Then area mesh could be kept as the document Ansys named .lis as the suffix and be introduced into Ansys software directly to mesh body, and then transferred the body mesh to mimics to assignment son the basis of CT values, once again import Ansys to establish 3-D finite element model.

The bad thing is that the DXT compression formulas for color images used in DirectX favors only the green channel (usual 30%, 59%, 11% formular), the blue/z channel isn't that important (especially if we renormalize later), but the image quality can be improved by preserving the red channel better.

坏的是，在使用DirectX的彩色图像DXT压缩公式主张只有绿色通道（通常30％，59％，11％公式），蓝/？通道并不重要（尤其是如果我们归一化后），但图像质量可以改善红色通道保存较好。
