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。

Results: No fiber layer and inflammatory tissues around any inserted implants were founded. New-grown osteoid tissue appeared faster in Bio-Ti implants than pure titanium and matured bone tissues comprise bone trabecula and Haversian canals appeared in 6 weeks, while at least 12 weeks needed to form matured bone tissue in control groups.

结果：所有种植体周围没有发现明显炎症组织或形成纤维层，Bio-Ti种植体组新生类骨组织生长较快，并于6w时已形成含有骨小梁及哈弗氏小管结构的较成熟骨组织，对照组12w时新生骨组织基本成熟。

The six groups classified by cluster analysis of SSR markers is consistent with the available pedigree and the result of combining ability. So it is feasible to analyze the genetic diversity of maize population by SSR markers and to distinguish heterotic group by method of mixed sampling.

6个玉米群体的聚类结果与系谱来源和田间配合力测定结果基本一致，说明，用若干单株混合取样分析玉米群体SSR的遗传多样性，进而对不同玉米群体划分杂种优势类群是可行的。

The clustering analysis classified the 24 cultivars into 2 groups and 5 subgroups, which respectively corresponded to indica-japonica differentiation and known rice heterotic groups based on pedigree information and blast reaction.

聚类分析将供试品种划分为籼粳差异明显的2个类群和分群结果与其系谱关系及抗性基本吻合的5个亚群，表明候选抗病基因标记可用于水稻品种的遗传关系、水稻病害控制和抗病育种方面研究。

The prototype has achieved Long-distance power supply by data bus, IEC61158-2 transmission technology and essential function of PROFIBUS-DP and can be connected to DP fieldbus system for transparent communication between the two sort of feildbus segment by DP/PA coupler and can be communicated with the DP master inerrably and continuously according to the primary PROFIBUS-DP communication protocol and process realization of state machine.

论文取得的主要成果包括：在国内目前允许的技术条件下，找到了一个PA产品开发的可行性方案，设计出能够通过数据总线进行远程供电PA原理型样机，实现了IEC61158-2传输技术以及PROFIBUS-DP基本功能，能够通过DP/PA耦合器将样机接入DP总线系统实现两类总线段间的透明传输，并按照状态机过程实现与主站的连续正确通信。

Sees only Moon crater which this at the beginning of war rests, from piece of on pale under black light and shade lamination dust, the slowly appearance, under the Moon small gravitation, true completely is being in the clouds quiet down, estimated needs at least for month-long the time, looked like the war the haze also must continue for a long time; Harbors the extremely serious mood, greatly leads several intimate assistants for doctor, passed through the thick dust dense fog, in basically cleans in the battlefield which finished to seek, the human brave warrior's skeleton already properly is processed early, but in the battlefield everywhere all has without enough time cleaning up each kind of weaponry, each kind of components which the guns, the bullet, the portable laser cannon and scatter, mixes with in the every large or small chippings, eliminates this also to have is wrecked innumerably, the kind of person robot makes threatening gestures to maintain each kind of death posture wreckage and the fragment, this gets down quietly the battlefield everywhere is filling the air the death breath, is constraining the people sensitive frail nerveDavid Dr.

只见这座大战初歇的月球环形山，正在从一片上淡下黑明暗分层的尘埃云中，慢慢的显露出来，在月球较小的引力作用下，真正的完全沉寂下来，估计至少需要一个月的时间，看来战争的阴霾还要持续许久；怀着极为沉重的心情，大为博士带领几位亲密的副手，穿过浓厚的尘埃迷雾，在基本打扫完毕的战场上寻找着，人类勇士的尸骸早已经被妥善处理，但是战场上到处都有来不及清理的各种武器装备，枪支、子弹、便携激光炮和散落的各种零件，夹杂在大大小小的碎石块中，除此还有无数被击毁的，类人机器人张牙舞爪保持着各种死亡姿态的残骸和碎片，这个沉寂下来的战场到处弥漫着死亡的气息，压抑着人们敏感脆弱的神经，大卫博士一行人，就这样巡视着并细心察看着这场战争的严重破坏。
