纹理

In chapter 4, the effects of orientation of rough surfaces on the lubrication behaviors of frictional pairs operating in the isothermal condition were studied and found that: the conclusion that the hydrodynamic load carrying capacity of transversely oriented surface is better than the isotropic surfaces is tenable only if the minimum clearance is relatively large, but the longitudinally oriented surfaces always decrease the load carrying capacity..

第四章在等温条件下，计算了粗糙表面的纹理方向对摩擦副润滑性能的影响，发现横向纹理表面具有比各向同性表面更大流体动力承载能力只有当最小间隙较大时才能显示出来，而纵向纹理表面总是使得流体承载能力下降。

To realize this subject, after grasping relevant knowledge that lamination and lamination shine upon soon, and then understand DirectX SDK in depth, and can use DirectX SDK to carry on the pinup picture of lamination in VC ++6.0 finally.

要实现该课题，就要在掌握好纹理和纹理映射的有关知识后，再深入了解DirectX SDK，最后能在VC++6.0中使用DirectX SDK进行纹理贴图。

One is to simply only render the polygons you intend to project the texture on when you have projecting texture active and the projection in the texture transformation matrix.

最简单的方法就是你当你打开投影纹理和设置纹理变换矩阵的时候仅仅渲染那些你试图把纹理投射上去的多边形。

This process is as follows: applying projective transformation on the plane, using interpolation method to acquired texture, and then mapping it on the model.

讨论了如何纠正平面纹理的透视变形，及其相应的纹理映射，其过程是在两视图重建的基础上，对原平面进行投影变换，并用插值方法获得纹理，从而映射到模型上。

There were high density images shaped as rope and slip in lungs of model control group rats and the pleura near the images were a little thickening. In MTX treated group, there were high density images shaped as slice along pulmonary veins. The veins of the blood vessels were obscure and the edges were unclear. In TPT treated group,there were multiple high density images shaped as tubercle and slice and the boundary were not clear. In XFC treated group, the lungs' outlines were clear and the veins were welldistributed. High density images shaped as spot were found in part lungs.

结果：HRCT表现为模型对照组大鼠肺轮廓欠清晰，肺部血管影扩张，边缘模糊且不规则，两肺有索条状密度增高影，邻近胸膜轻度肥厚；甲氨喋呤组大鼠肺部可见沿着肺纹理分布的斑片状密度增高影，肺血管纹理模糊，边缘不清楚；雷公藤多苷片组大鼠两肺可见多发性结节状及斑片状密度增高影，境界欠清晰；新风胶囊组大鼠肺轮廓清晰，肺纹理分布均匀，部分肺组织显示斑点状密度增高影。

Consequently, this paper presents a texton-based algorithm of texture image segmentation. At first, Harr wavelet is utilized as a transform tool so that texture subimages of different directions are produced.

首先 ，以 Harr小波为变换工具，得到具有方向性的纹理子图象；然后给出了一种新的纹理基元提取方法，并在此基础上，应用统计方法和矢量场，对纹理区域进行由粗到细的分割。

In this paper,the condition that gas flow through wood in the pattern of linear flux wasdetermined from the theories of thermodynamics and fluid mechanics.The expression of flow-resistor of tracheids is reduced with the continuity equation and the equation of motion indifferential form.The flow-resistor network is constructed by means of the theory ofpercolation.The equivalent flow-resistor was evaluated by utilizing the real spacerenormalization approach.

本文根据针叶材管胞的解剖结构，运用孔隙介质流体力学的理论，导出了管胞关于气体渗透流阻的数学表达式；继而根据管胞纹孔在三个纹理方向上的连接特性，利用管胞流阻建立了一个描述针叶材三个纹理方向气体渗透性的三维流阻网络；然后运用实空间重整化变换的方法，求解试件流阻网络三个纹理方向的等效流阻，并由此计算试件相应的气体渗透系数；最后用我国南方常见的人工林马尾松木材试件进行渗透系数实际测量，与理论计算结果进行对比分析，以验证三维流阻网络及其理论的准确性。

This way, every time we need memory to load a texture, the texture manager checks whether there's any texture with the same characteristics (size and format, which must be the same to reutilize the texture).

在每一次需要在内存中加载一个纹理时，纹理管理器先检查是否有同样类型的纹理。

The former image,the reference image is divided into a series of textures standing for different surficial configurations,and its is assumed that the gray value of the above textures is modeled as Gaussian distribution s.

对于两幅同一地点、不同时刻的图像，先将前一时刻的遥感图像分割成一系列代表不同地表形态的纹理，假设前一时刻图像的灰度分布在这些分割所得的纹理区域上可以用高斯分布描述，则后一时刻的图像在这些纹理区域上远离高斯分布的像素点便是异常的变化点。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
