隨著綜合保障工程思想在我國工業界和軍方不斷普及和推廣應用,裝備綜合保障能力的評估成為檢驗裝備保障性設計好壞、裝備使用保障效能高低以及裝備后續型號發展決策的主要手段,同時隨著計算機模擬技術的不斷完善和成熟,裝備效能分析與評估研究進入了一個新階段,我們可以在導彈武器綜合保障效能分析與評估所需使用與維修數據原始積累的基礎上,利用計算機模擬導彈武器在真實使用環境中的使用維修過程,達到對導彈武器系統的綜合保障能力進行更全面、客觀、準確的評價目的,從而為裝備保障部門制定最優的保障方案提供更好的決策依據。But marxism and post - modernity have the essential difference. marxism also give positive side as well as its critics, and purchases the ultimate transcendence, so it is dialectical ; but post - modernists just purchase the pure deconstructions and damage, and totally deny the enlightenment spirit, finally going to the opposition of rationalism. this decides that it is not social thought that has broadly developed future, so we should have dialectica l manner
但馬克思主義與后現代主義又有著根本的不同,馬克思主義在批判的同時還有肯定,並且追求最終的超越,是辯證的態度;而後現代主義追求單純的解構和破壞,完全否定啟蒙精神的態度走上了理性的反面,決定了它不是一種有廣闊發展前景的社會思潮,我們要以辯證的態度來對待它。With the very low water to cement ratio, rpc has ultra - high strength high ductility and low permeability. in this paper, the compressive strength of rpc can reach to a high point with the number approximately 135mpa. as illustrated from the study results, we can approve some fundamental conclusions : there are big effects on rpc with deferent kinds and properties of raw materials and deferent curing conditions ; stress - strain curve shows the process of destroy with rpc samples ; x - ray diffraction analysis indicates that heat treatment at temperatures 90 accelerate the hydration of rpc sharply, therefore, mechanical and microstructural properties of rpc are highly dependent on heat treatment ; it is believed that rpc materials have excellent resistance to chloride permeability ; during the heat treatment, the shrinkage of rpc developed quickly because of chemical reactions ; the rpc with slag mostly has the advantage of rpc without slag about resistance to solutions corrosion
研究結果表明:通過對rpc各組分摻量變化的研究,可以找到rpc的最優配合比;試件成型后的熱養護制度對rpc的性能影響巨大; rpc的抗壓應力?應變曲線可以反映出試件受破壞時微裂紋的擴展情況,剛纖維的摻入可以大幅改善rpc的韌性; rpc在成型后存在較大的收縮,而其中的化學收縮要遠遠大於乾燥收縮; rpc具有很強的抗氯離子滲透性能,漿體的密實度很高;通過x射線衍射實驗,可以發現rpc的膠凝體中ch晶體已經幾乎不存在,膠凝體主要由c - s - h凝膠和未水化水泥顆粒組成;在抗溶液侵蝕的實驗中,摻礦渣rpc的抗溶液侵蝕性能在絕大多數情況下要好於不摻礦渣試件,酸、堿溶液和浙江工業大學碩士學位論文摘要一些鹽溶液都會對rpc的結構產生侵蝕作用,但是機理各有不同。( 6 ) conclusion was obtained by the analyzing the mechanics environment and the stability of the lanslide on the right bank after the dam built : the value of the rock mass stress increased and the tensile stress region obviously reduced, the direction of the principal stress was unchangeable the dam and the landslide were stable under the dangerous condition ( the reservoir and at the same time the earthquake was viii ), but when the water lever suddenly fell and did not think of other force, safe factor evidently reduced, the dam and the landslide will be destroyed under the most dangerous condition ( the water lever suddenly fell and at the same time the earthquake was vi ) ; the stability of the landslide will be destroyed by the horizontal thrust under the most dangerous condition or ; the physical and mechanical parameter will be reduced due to long period filter, the landslide will be destroyed too
( 6 )建壩工程荷載條件下河谷巖體力學環境分析及右岸古滑坡體的穩定問題分析得出:建壩后河谷的巖體應力量值明顯增高,同時左岸的張應力區的范圍及量值明顯減小,主應力的方向依然與模型的底邊界垂直;大壩建成后逐漸蓄水階段以及同時考慮本區最強地震力的作用等各種不同的工況條件時,滑坡體及壩體總體上仍處于穩定狀態;水位驟降時,在未考慮其他外力作用的情況時,滑體的安全系數將顯著降低。若考慮水位驟降及本區最大地震力的共同作用,壩體將在滑坡體下滑推力的作用下產生破壞;建壩后水平推力對右岸古滑坡體穩定性的影響分析可以看出,在最危險的工況條件下,壩體及滑坡體也將處于臨界狀態;在長期滲透變形的作用下,由於滑帶的物理力學參數的降低而有可能導致壩體失穩破壞。Through the research of the tension in vivo, the immediate retraction rate and histology examination about the different ways and different maintaining, we get : the increase area of the rapid and conventional expansion has little difference with the expanded time ; however it has significant difference with the maintaining time. it shows that shortening the expanded time is feasible in clinic, but shortening the maintaining time is out of the question ; after the capsule is removed, immediate retraction rate of the expanded skin notably decreased, significantly different from those with intact capsule ; the collagen content of the rapid expansion is just the same as the conventional expansion, but the changes of the histology dependences on the maintaining time. comparison with conventional expansion, rapid expansion has no significant drawback ; maintaining a period after expansion can greatly increase the area of expanded skin and reduce immediate retraction

從材料設計的思想出發,採用宏觀與微觀、材料科學與力學相結合的方法,對鎢基復合材料的熱傳導行為、材料在熱沖擊載荷下的內部熱應力場及材料細觀結構的破壞行為進行了詳細的理論研究.根據鎢基復合材料的細觀組織結構建立了材料細觀模型.在宏觀分析的基礎上,分析了材料微結構內部的破壞行為.分別取試件心部與邊緣主應力值最大點的應力狀態,施加在所建立的模型上,用有限元方法計算了模型內部的彈性應力場.結果表明:試件主應力最大值首先產生在試件內部,此時,如果材料發生破壞將先從夾雜中開始;加熱一段時間后試件中的最大主應力值轉移到試件邊緣,此時材料發生破壞將先從基體中開始In part one, the general of reclamation of arable land for reforestation : basing on resulting lots of data, author referred to many measures taken by america and china in the reclamation of arable land for reforestation and took the comparison, which concluded the following : china does not take the ways that the developed countries firstly destroyed before protection ; carrying out the reclamation of arable land for reforestation step and step is the important step which improves the reasonlesss utilization of land ; because of the weak economic base in the reclamation of arable land for reforestation of china and the low rate of labor, we should enlarge the content of science and technology, improve per yield of the remaining cultivated land and solve the self - sufficiency of grain, meanwhile the government should strengthen the transfer of remaining labor, adjust the industrial construction and lead the construction of small cities and towns ; the implement of reclamation of arable land for reforestation does not leave the support of the government ; we should carry out the reclamation of arable land for reforestation according to law ; the reclamation of arable land for reforestation does not be seen the effort in the short time, we should insist in a long time. which can have the result
本論文共分八個部分:第一部分退耕還林概況:筆者在查閱大量資料的基礎上,參閱美國與中國的退耕還林過程中所採取的各項措施並進行比較,得出了以下結論:中國不能重走發達國家先破壞后保護的道路;有計劃、有步驟地實施退耕還林是改善不合理土地利用現象的有力舉措;中國退耕還林經濟基礎較為薄弱,農業勞動生產率低,退耕還林后,必須加大科技含量,提高剩餘耕地的單產,解決糧食自給問題,同時,政府應加強剩餘勞動力轉移,產業結構調整及小城鎮建設的引導;退耕還林的實施仍離不開政府的扶持;依法退耕還林;退耕還林不是在短期內能見到效果的,長期堅持必有成效。該部分最後論述了目前國內退耕還林工程政策、管理方面的現狀及其存在哪些問題尚待改進或繼續深入研究,並需要進一步完善。第二部分退耕還林背景分析:針對我國目前生態環境建設中的退耕還林工程,就其產生的根源從社會經濟背景、生態環境背景及西部大開發三個角度進行了全面、系統的分析。They are binding number, scattering number, integrity and edge - integrity, tenacity and edge - tenacity, toughness etc. these parameters show the most serious damage and the situation of a network after the damage simultaneously, so they measure the connectivity of graphs more accurate
這些參數同時反映了一個網路可能遭到的最大程度的破壞和被最大程度破壞后剩餘部分的工作狀態,因此更好地刻畫了圖的連通性。But as we use umc 0. 18 m cmos process which leads to a consideration about changes of models, thermometer and power source which can reach 45 combinations. at last, we select 9 combinations in worst conditions to do simulation, in order to reach a higher rate of finished products than 95 percent of it, which means that the design must reach a very high degree
但是,本次設計所採用的是umc0 . 18 mcmos工藝,並且模擬時考慮模型變化,溫度及電源變化多達45種組合的情況下(后來經選出9種最壞情況作模擬) ,保證95以上的成品率,這就對設計提出了很高的要求。In the wavelet image compression system , the choice of wavelet basis directly determines the statistical characteristics of wavelet coefficients, thus it not only affects subsequent processes, but also affects the final compression ratio and the the quality of reconstructed image. the method of realizing wavelet transform determines computational complexity, whether the transformed data can be lossless recovered or not, etc., accordingly it can affect the time spending on compression and the quality of reconstructed image
