In view of the existing problems of traditional resource allocating networks, a design method for RAN based on rough set and orthogonal least square was proposed. Firstly, rough set was applied to intelligent data analysis for extracting typical characteristics from the training samples, and then OLS was used to select best renters as the hidden layer nodes.

The synthesis scheme we developed can deal with changes in visibility, produce perspectively correct views and handle the distortion around the circumferences in the synthesized views. In our scheme, the area without corresponding points was first determined by using Fourier transformation in order to deal with distortion problem, within the mutual overlapped area the z-buffer values of matched key points were computed so that the visibility in novel views can be handle correctly, lastly the common points in new views are rendered through epipolar geometry constraint.

算法的步骤为：利用傅立叶变换方法确定相邻源图像无对应点的区域；然后，利用尺度空间和相位一致原理在共同区域提取及匹配边缘上的关键点，计算其深度值，并在新图像中由该值判别虚拟图像中的可见性；再由关键点恢复极线约束，通过极线间的位置和颜色插值生成虚拟图像中有对应区域的一般点；在确定极线位于无对应点区域段后，利用加权平均或放大插值的方法实现了源图像无对应点区域在虚拟图像中的自然过渡。

In order to study the expression and functional characteristics of dehydrin gene during different growth, and make the polycolonal antibody, using wheat plumelet under the water deficit condition as experiment material, and its total RNA was extracted. The target dehydrin gene through RT-PCR was got, connect to the cloning vector PUCM-T, recombination expression plasmid PET-32a-wzy1-1 was constructed according to recombination of cloned vector PUCM-T-WZY1-1 of wheat dehydrin gene in this experiment.

方法的具体实现为：首先利用相位一致方法提取各图像中边缘上的角点特征，对特征角点进行初始匹配，然后利用初始匹配的角点计算变换矩阵的初始参数，再以光强度差的平方和为优化目标函数，在优化的过程中逐步获得变换矩阵的最佳参数，最后对重叠区域运用渐入渐出的方法实现了光强或颜色的自然过渡。

Obtaining the qualitative factors,and achieve the conversion from qualitative to quantitative by the theory of quantification, and in combination with other quantitative factors. Then use SPSSto analyse its correlation and variance.

The result that such causing is, to product key word, the home page that stands because of intranet nothing more than it is company brief introduction, the product is revealed, the extraction content of news center respect, fixed position of entrance of result of key word search is in home page, the user is returned from page of product of home page reentrance, if your product navigation is done,not be so good, the user can not find a product easily certainly, so the Google rank of product key word does not have how old meaning actually.

这样造成的结果是，对于产品要害字来说，因为企业网站的首页不外乎就是公司简介，产品展示，新闻中心方面的提取内容，要害字搜索结果入口定位在首页，用户还得从首页再进入产品页，假如你的产品导航做得不是那么地好，用户不一定能够很轻易地找到产品，那么产品要害字的Google排名实际上没有多大的意义。
