The thesis is based on income question, forest coverage rate and grop production.to beging with, date envelopment analysis is proved that it can be applicated into grain for green in shan-bei district, and then in view of the fact, seven esential factors which have influence on the project are found out: expense of dam, expense of crop,expense of cash tree ,expense of defense tree,other economic crop,expense of grass and graziery;and the output factors include:income of gdp,pure income per captia,the area of decreasing land loss,graziery income ,crop production,income of tree,the totle income of economic crop.after the date of each facts are puted into dea model,unefficiencial decision making units found.the data that are got through adjusting unefficiencial dmus dy dea can offer guide in shanbei district upgrading of an industrial structure.at the same time ,taking into account some possible problems in or after grain for green in shan-bei district,the thesis bring out some propesal to improve the circumstance,enhance the life level and putthe relation of population,resource and circumstance into a healthy orbit.

论文以解决陕北地区的收入问题，植被问题以及粮食产量问题为出发点，首先从理论上分析了包络分析方法在陕北地区退耕还林中运用的可行性，然后结合陕北地区目前的实际情况，综合分析出影响陕北地区退耕还林的关键的七个因素作为输入指标：水利水保设施投入，农作物投入，经济林种支出，防护林支出，其它经济作物，草类支出，畜牧业投入；以退耕还林所要解决的最终问题作为输出指标：GDP收入、农民人均纯收入、水土流失减少量、牧业总产值、粮食产量、林业总产值、其他经济作物总产值。将各指标所对应的数据代入模型后，通过分析求解得出非有效的决策单元，再运用包络分析方法的一些基本原理对非有效的决策单元进行调整，由此所得的数据对陕北地区的实际投入具有很好的指导意义。同时，又针对陕北地区在退耕还林过程中以及之后可能面临的困境，提出了一些建议和对策。最终使得陕北地区的投资环境尽快得以改善，使农民尽快脱贫致富，使人口、资源、环境的关系尽快纳入良性循环的轨道上。

Theoretically, its calculation complexity is studied, while it is tested empirically by learning multi-samples generated randomly. The comparative analysis and applications show it has some merits of rapid searching and good clustering effect. B3. An immune network optimization algorithm with information feedback, which can solve special complex function optimization problems with high dimensions which objective functions are formed by summing multi-subobjective ones, is constructed based on the clone selection principle and the immune network regulation of the idiotype immune network.

为了对免疫系统中抗体如何学习抗原特征的整体行为有一定的认识，从单个抗体识别抗原及多个抗体并行识别抗原的特征出发，利用免疫应答的相关原理及免疫细胞的免疫功能设计了适合于批量样本聚类的抗原特征学习算法，理论上分析了其计算复杂度，获得了此算法中的关键参数与其搜索性能的关系；应用上，该算法通过对实际的多样本学习，获得了搜索速度快及聚类效果好的优点，比较分析表明这种方法是可行的和有效的。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
