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 ( dmu ) 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 circ umstance, enhance the life level and put the relation of population, resource and circumstance into a healthy orbit
因此，加快退耕還林還草，調整土地利用結構和產業結構，已成為實現山川秀美工程和可持續發展戰略的必經之路。論文以解決陜北地區的收入問題，植被問題以及糧食產量問題為出發點，首先從理論上分析了包絡分析方法在陜北地區退耕還林（草）中運用的可行性，然後結合陜北地區目前的實際情況，綜合分析出影響陜北地區退耕還林（草）的關鍵的七個因素作為輸入指標：水利水保設施投入，農作物投入，經濟林種支出，防護林支出，其它經濟作物，草類支出，畜牧業投入；以退耕還林所要解決的最終問題作為輸出指標： gdp收入、農民人均純收入、水土流失減少量、牧業總產值、糧食產量、林業總產值、其他經濟作物總產值。將各指標所對應的數據代入模型后，通過分析求解得出非有效的決策單元，再運用包絡分析方法的一些基本原理對非有效的決策單元進行調整，由此所得的數據對陜北地區的實際投入具有很好的指導意義。 -
In the present research, scanning electron microscope ( sem ), laser raman spectroscopy ( lrs ), x - ray photoelectron spectroscopy ( xrs ), x - ray diffraction ( xrd ) and electron probe micro analysis ( epma ) were utilized to investigate the difference in micro - structure and elements distribution between domestic and foreign pdcs. combined with analysis on current manufacturing process, the mechanism for the difference was discussed. scanning electron microscope ( sem ), laser granularity analysis, atom emission spectroscopy ( aes ) and plasma emission spectroscopy ( icpaes ) are also utilized to investigate the grain shape and impurities of key material - diamond power
本課題採用掃描電鏡、拉曼光譜、光電子能譜、 x -射線衍射分析、電子探針等方法分析了國內外聚晶金剛石-硬質合金復合片在微觀組織結構、元素成分分佈方面的差異，結合對現有燒結工藝的分析，研討了造成這些差異的機理；採用掃描電子顯微鏡、激光粒度分析、原子發射光譜、等離子發射光譜等方法對關鍵原材料-金剛石微粉的晶形、雜質含量進行了比較分析測試。 -
