Basis on the statu quito , the basis of the selecting title , the main theoretical foundations and the researching approachs , the thesis analyses the advantage of the development animal husbandry and the existing questions in jiuquan oasis . the author thinks the restricting factors in animal husbandry development are the limited meadow area , the serious soil erosion , the land determinations , the worse management regime , the severe hazard on mice , the fluctuating product in meadow and so on . and then the author has appraised the ecological fragility in jiuquan oasis 論文在論述了酒泉綠洲畜牧業的研究現狀、選題依據、主要理論基礎及研究方法的基礎上,分析了酒泉綠洲畜牧業發展的有利條件,認為人工、半人工草場面積小,水土流失嚴重,土地退化,草畜比例失調,草場退化,草原管理制度不健全,鼠害猖獗,牧草產量年度變化大,產草量和草場利用季節不平衡,生產經營理念落后,成為酒泉綠洲畜牧業發展存在的主要問題,并對酒泉綠洲的生態脆弱性進行了評價。

Because of these , the author has gone to jiuquan to investigate the staru quito to the best of his ability in 2001 . the author has collected a lot of data as the basic research materials of this thesis with the comrade ' s support in the animal husbandry bureau , the water conservancy bureau , and the land board in jiuquan 為此,筆者于2001年去酒泉進行實地考察調研,并盡己所能了解情況,在酒泉市畜牧局、水利局、土地局有關同志的支持下搜集了許多數據資料,為本論文的研究奠定了基礎。

The important meaning in which this direction studied has lain in establishing the connection between the material science of concrete and civil engineering , analyse the strength in terms of material microcosmic or the mesoscopic , have important meaning to understanding , know the essential law of the strength of concrete . this text divides six chapters altogether . chapter one reviewed the pore structure in nowadays domestic and international research current situation , including the concrete examines research , research of the pore structure model and the research current situations of pore structure and strength relation of the pore method , have introduced some most important achievements of structure research of pore ; chapter two narrated much yardstick of the material mesoscopic structure of concrete and principle of examining pore technology of material of concrete , and the commonly used sign parameter in discussedding the pore and material pore of quito of cement and analyse , have explained that the influence factor of mip to the result of study of pore , has pointed out the limitation in mip in the pore structure ; analyse porosity and strength relation development course of model emphatically , and has carried on comparative analysis to the existing model , has pointed out the weak point of the original model ; on the basis of “ ing integrate synthetically “ , propose concrete pore structure compound body model and pore physical model of systemlex body ; chapter five carried on the corresponding test data to compares to the model parameter appearing in model of chapter four with and analyses , have received k value of the characteristic of strength of matrices of reflecting according to the method to return to analysis , and calculate the influence produced on the strength of concrete in revision that can probed into the content of cement , elastic mould and surface energy , exactness of the inspection model ; chapter six is the conclusion , according to studying the survey this text to some research conclusions of the pore structure and making corresponding prospect to the structure development of pore 第一章回顧了孔結構在當今國內外的研究現狀,包括混凝土測孔方法的研究、孔結構模型的研究及孔結構與強度關系的研究現狀,介紹了孔結構研究方面的一些最重要的成果;第二章敘述了混凝土材料細觀結構的多尺度性及混凝土材料測孔技術的原理,并討論了水泥基多孔材料孔隙分析中常用的表征參數,也說明了壓汞法測孔對研究結果的影響因素,指出了壓汞法在孔結構研究中的局限性;第三章是著重分析了孔隙率與強度關系模型的發展歷程,并對已有的模型進行了比較分析,指出了原有模型的不足之處;第四章在“綜合集成”的基礎上,提出了混凝土孔結構復合體模型和孔系統的物理模型,并模擬了該模型下由各單體并聯形成的復合體的斷裂過程,最后根據所建模型編制了相應的計算程序,可根據輸入的孔徑分布與水泥含量等參數,實現混凝土理論強度的計算;第五章對第四章模型中出現的模型參數進行了相應的試驗數據對比分析,根據回歸分析的方法得到了反映基體強度特征的k值,并從理論上探討了水泥含量、彈性模量和表面能的修正對混凝土強度計算產生的影響,檢驗模型的正確性;第六章是結論與展望,根據研究綜述了本文對孔結構的一些研究結論并對孔結構發展作了相應的展望。
