查询词典 topographical features

The topographical parameters have been analyzed by taking into account the thermal effect during the friction process. As the results, three kinds of typical topographical features have been observed for the worn surfaces of C G iron with various P content. Namely, C G iron with 0.05% P, 1.30% P, and 0.70% P show worn surfaces characterized by groove ridge, peak pits and their combined topography. The C G iron specimen with peak pits type worn surface topography showes the lowest wear rate and highest friction coefficient, while that with groove ridge type worn surface topography shows the highest wear rate and lowest friction coefficient. The groove ridge type worn surface has a relatively large value of surface height deviation and void volume ratio and negative large value of skewness, which is contrary to the peak pits topography.

结果表明：度销磨损表面主要呈现犁沟型、孤岛型及二者的混合型3种形貌特征，其中具有孤岛型磨损表面形貌特征的试样的摩擦系数较高，磨损率较低；而具有犁沟型磨损表面形貌特征的试样的摩擦系数最低，磨损率最高，分析表面形貌参数发现：犁沟型表面形貌具有最大的表面高度偏差和表面空隙率及高负值的表面高度分布参数；而孤岛型表面形貌的表面高度偏差和表面空隙率最小，表面高度分布参数为高正值。

According to the life form of species and their roles in communities, 6 species groups are used to do ordination analysis and environmental interpretation. The result suggests that:①Despite the strong man-made disturbance at lower altitude sites, the number and character of evergreen species show an change along the altitude gradient.②The rare and endangered species concentrated at two sectors along altitude gradient, corresponding to the upper and lower borders of the mountain mixed forest belt of evergreen and deciduous broad-leaved species.③The pioneer tree species concentrated on the middle and upper positions at lower elevation.④The deciduous accompany tree species show a great diversity on middle and lower position at middle and higher elevation.⑤Coniferous species differentiate along elevation and local topographical gradient.⑥Deciduous species in Quercus, Castanea, Fagus, Carpinus genus as well as coniferous species play primary community-constructing roles at different topographical position at Dalaoling region.

此外，年内短期气候和地形变化对物质平衡的影响均大于多年平均状态，在高值物质平衡区，气候变化对物质平衡的影响大于地形变化的影响；而在低值物质平衡区，地形变化对物质平衡的影响则大于气候变化对物质平衡的影响。

Making use of this model I have a taste in Yan Shan Reservoir watershed in He Nan Province: I start on the information of the surface in this area, give every grid cell the proper parameters by distilling them from the map of how the people use soil and the map of soil type in this area; In order to get the topographical information, I add numerical value to a abundant of contour lines and points in topographical map, use the software Arc View of GIS to create Digital Elevation Models automatically, get every volume of the reservoir from the water level 99m to 117m. By using a special module of the software, I distill triumphantly the grid cells elevation value, slope value, flow direction, flow accumulation, watershed, stream network, isochrones and so on.

本文在分布式水文模型的基础上，对河南省燕山水库流域洪水入库计算模拟方面作了一些研究：从燕山水库流域的下垫信息开始着手，依据流域的土地使用类型图、土壤分布图确定每个栅格单元的土壤特性和土地利用方式，进行下垫信息的参数化，得到单元模型所需的参数值；为了提取地形信息，本文通过对流域地形图海量数据加载高程值，利用GIS软件自动生成流域内的数字高程模型，提取了流域水文模型所需要的库容曲线；通过栅格自动划分，提取栅格单元的高程、坡度、栅格流向、流域边界、虚拟河网、流量积累、等时流线面积分布等分布式水文模型的流域特征。

There are three main methods in face localization: localization according to face outline, localization according to complexion and localization according to templates constructed by some standard sample images. As to feature extraction, it can be divided into two parts because face features can be divided into geometrical features and algebraic features. While extracting geometrical features, the features of eyes, nose, mouth, eyebrows can be gained by some image processes: binary, sharpen, smooth, projection, calculating gradient and so on. In order to extract algebraic features, we can do some mathematical transformation for the digital images such as singular value decomposition, K-L transformation.
