特征方向

The ratio reflects the degree of anisotropy of trabecular patterns, and is successfully used in our pattern classification.

最大和最小方向分形维数的比值定义为一项备向异性特征。

In this time, we can recognize the number image depending on the location of the end-point. If the y-coordinate of the end-point is bigger than half of the height of the number image, the recognized result is 6. Else the result of recognition is 9. Then if there are two end-points and there is no trifurcate point, the possible recognition result of the number image is 2, 3, 5 or 7. Here, we need to recognize the number image by dint of the end-point directions and locations.

最后，我们根据特征提取的结果进行分类识别，如果没有端点、没有三叉点，则识别结果为0；如果无端点，两个三叉点，则识别结果为8；如果只有一个端点、一个三叉点，则识别结果可能为6或9，这时只需考虑端点的位置，即可将6和9区分开来；如果有两个端点、无三叉点，则识别结果可能为2、3、5、7，这时需要加入端点的位置和方向辅助判断。

The general feature of the plastic deformation is similar in both charging or uncharging hydrogen specimens.

发现：氢的存在并不改变在Ⅰ型或混合型载荷作用下，裂纹尖端的塑性变形特征，即在主裂纹前端，应变呈不对称分布，裂纹尖端Schmid因子决定了条带状局部形变带的轴线方向。

Curvature is the result of geometric structure in image; a new third order partial differential equation is proposed which transports curvature information along isophotes. The third order POE is morphologically invariant. Helmholtz vorticity equation which annihilates vorticity and third order POE which forward transports curvature information are coupled to be a new model.

曲率是图像几何特征作用的结果，本文提出沿等照度线方向传输曲率信息的三阶形态学不变偏微分方程，并将抑制涡量的无粘亥姆霍兹方程和正向传输曲率信息的三阶偏微分方程耦合。

However, with the development of autocratic monarchy in Han plitical power, the growing conflicts between the Daoist political concept of governing by noninterference and autocratic monarchy lead to failure of the Daoist school in achieving its historical mission of deifying monarchical power.

但是，随着汉政权君主专制集权的发展，道家&无为而治&的政治理念与君主专制集权的发展表现出诸多不适应性，表现出与君主专制集权的目的和方向、君主集天下权力于一身的个人特征相矛盾。最终，道家没有完成君权神化的历史使命，走下了政治舞台的中心。

This thesis keens on the DM utilizing research in coal mine gas forecasting. It is explained about domestic and outboard researching present conditions of time series data mining, time series analysis, formalized expression and model establishment of time series. Through analysising the features of coal mine gas observing data and several species of model. This thesis declares a suitable data and model ARMA.

本文的主要研究方向是时间序列数据建模及其在煤矿瓦斯预测中的应用研究，文中就时间序列数据建模的国内外研究现状、时间序列分析、形式化表示和时间序列的建模等进行了详细的论述，在分析了煤矿瓦斯监测数据的特点和多种模型的特征基础上，提出了本文所适用的数据模型为ARMA，同时，对特定的数据进行了数据建模，并对结果进行了分析和验证。

Understanding the characteristics of multiple modernities is of great theoretical and practical significance to recognize the world and its developing direction, and to recognize special actuality of various societies as well.

理解现代性多样性的特征对于认识当今世界及其发展方向、认识具体社会的特殊现实，在理论和实践上都具有深远的意义。

S.N.Eisenstadt exposed the logic of multiple modernities through questioning and criticizing social evolution theories after Marx's and Weber's, rethinking complex modern history, making comparative historical analysis to observe dynamical process and developing orientation of modernities from origin and the spreading to ultimate shaping.

艾森斯塔特通过对自马克思及韦伯以来的社会进化理论的质疑和批判，对纷繁复杂的现代性历史的反思，采用比较历史的研究方法考察了现代性从起源、传播到成型的动态变化过程和发展方向，揭示了现代性沿着多样性特征展开的逻辑。

Four images on the image surface respectively correspond space scene information on the four direction and are subjected to character matching and image mosaicking based on the overlap area between the two adjacent scene images, in order to obtain a intact space panoramic image.

像面上四幅图像分别对应空间四个方向上的场景信息，依据相邻场景图像之间的重叠区域进行特征匹配、图像拼接处理，就可以得到一幅完整的空间全景图像。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
