A method for categorizing university positioning is presented based on an analysis of current categories of university positioning.

在对大学定位的必然性和现有的大学定位分类方法分析的基础上，提出了自己的分类方法，并运用这一方法对省属高校进行了分类研究。

So, this paper is about the research of a Rough Set-Based method classing customers applied in Customer Relationship Management. Firstly, we obtain data from the Customer Relationship Management system, and convert them intorelevant decisiontable.

但是，在客户关系管理中使用的基于粗糙集理论的客户分类方法却较少见，而利用粗糙集理论进行客户分类具有一定的优势，因此本文将在粗糙集理论的基础上，采用了一种基于粗糙集的客户分类方法。

The proposed algorithm first detects smooth intervals based on gray variance from the original frame sequence, then concatenates them to constructs a new frame sequence. After that, video features such as pixel-wise difference, HSV histogram difference and edge histogram difference are fed to a SVM classifier to decide the types of different shot boundaries.

第一级分类器根据视频帧灰度方差特征，将无明显变化的视频序列从原始视频序列中分离出去，得到一个新的视频序列；第二级分类器在新视频序列的基础上，提取视频图像的像素对差值、HSV空间颜色直方图的各分量差值以及边缘直方图X，Y分量差值等视频特征，并采用支持向量机多分类策略进行镜头边界类型的检测。

It is a long way to go to give a scientific classification on the basis of sufficiently numerating and determining the scope of environment protection activities, especially in the sense of practical operation.

如何在充分列举、确定环保活动范围的基础上，进一步进行科学的分类，满足分类核算进而分类分析的要求，还有很长的路要走，尤其在实际操作这样的层面来考虑问题。

One of they is a cluster method based on rough entropy and orients to discrete attributes.

主要成果如下：（1）分析遥感影像分类特征的离散化方法及其对分类规则提取的影响，提出适用于遥感影像分类的基于改进粗糙熵的离散特征聚类方法和基于动态层次聚类的连续属性离散方法。

Based on the survey of community plots, a quantitative analysis of the communities at Luya Mountain is performed with TWINSPAN Two Way Indicator Species Analysis and DCA Detrended Correspondence Analysis methods. 82 quadrates collected from Luya Mountains were classified into 28 types by TWINSPAN, which belong to seven vegetation types. The result of DCA indicated that those 28 types were reliable. Diagonal line of the two-dimensional ordination diagram of DCA reflects the gradient changes of elevation, temperature and humidity. It is considered that the major factors that restrict the community distribution of the mountains are elevation、temperature and humidity.

本文在群落样方调查基础上，采用双向指示种分析法TWINSPAN和除趋势对应分析DCA对山西芦芽山植物群落进行数量分类和排序TWINSPAN等级分类将芦芽山82个样方分为28类，可归属于7个植被型，分类结果反映了植物群落类型与环境梯度之间的关系，并在 DCA二维排序图上得到较好的验证DCA排序轴对角线基本反映了海拔、温度和湿度的梯度变化，表明群落生境所在地的海拔、温度和湿度是决定群落分布的主要因素

In the Subtotals dialog, in the Group by box, select the column that you want to add the subtotals to.

在分类汇总对话框的分类依据框里选择要添加分类汇总的列。

For Hilly area, in order to compress the topographic effect, the simple ratio of band and simulated reflectance techniques were used, the ratio band and Simulated reflectance band which combined with original bands, were use to vegetation classification, what's more, Tasseled cap processing was used.

低山丘陵地区的植被分类，我们采用简单比值处理和模拟地表反射技术来抑制地形遮阴的影响。把经比值处理的波段和经模拟反射处理的波段，与原始TM波段进行组合，并用于对山区的植被进行分类，分类结果如下

Data from TM images from the years1986,1993, 2000 and 2006 around Shenfu coalmine area were used to exbract normalized difference vegetatio n index by the software ERDAS firstly, then using spatial modeler of ERDAS compute vegetation fr action and classify through unsuperˉ vised classification.Finally,we get vegetation fraction mapping of c oalmine within 1986～2006.It clearly inˉ dicate that the coalmine vegetation fraction increase in whole but d ecrease in some colemine district.

通过利用榆林市神府矿区1986、1993、2000、2006年四景同期TM影像数据，使用ERDAS软件首先提取植被指数，根据像元二分法利用ERDAS的建模工具Spatial Modeler计算出矿区的植被覆盖度，利用非监督分类方法对矿区的植被覆盖度进行分类、赋色，最后得出矿区1986～2006年的植被覆盖度分类图，定量的说明了矿区20 a年间的植被覆盖变化情况：植被覆盖度整体提高，在局部矿区则有所降低。

However, if the trigonal control point and datum transformation model do not exist, the result of base station single point absolute location can be used as reference coordinate, the measured result of which can be geo_referenced to remote sensing image using some tiepoints on the basis of the first result above.

例如 ，在利用遥感影像分类时，需要在外业获取用于监督分类的训练样地或是分类结果精度检验样地的大地坐标信息；在进行稀有树种区域分布特征调查时，希望能在遥感影像上标识出每个树的具体位置；发现某河段发生污染时，很可能需要将它的精确位置以线或面的形式显示在其它矢量或栅格图层上。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
