There is no precedent to model land use and land cover change of arid region in china. and zhangye city located in the transition of three physical geographical region of china, is the significant part of north - west arid region, which is the sensitive area and zoological brittle zone. the evolutive process and mechanism of land cover change law is different from east region
國內對乾旱區土地利用覆蓋變化模擬的研究尚無先例，且張掖市是我國西北乾旱區的重要組成部分，處在我國三大自然地理區的過渡位置，為環境演化的敏感區和生態脆弱帶，土地覆蓋的演化過程和機制有其不同於東部地區的特殊規律，所以張掖市土地利用覆蓋變化模擬的研究對乾旱區現代環境變化的人為影響研究有著極為重要的理論和實際意義。The planeness and integrality of the flier - plate were ensured effectively by exerting restrictive pressure, controlling heating and cooling rate, lowering welding temperature or reducing welding time as much as possible, etc. theoretical model of creating quasi - isentropic compression via 93w - ofc - tc4 - a1 - mb2 system flier - plate with graded wave impedance was established, and numerical simulation of the impact process was then carried out
採取施加外部機械力、控制升降溫速率以及盡量降低焊接溫度或減少焊接時間（防止脆性金屬間化合物的過度增長）等措施，確保了焊接接頭的平整性和界面結構的完整性。建立起梯度飛片擊靶的理論模型，對93w - ofc - tc _ 4 - al - mb _ 2系波阻抗梯度飛片的擊靶過程進行了數值模擬計算。The results revealed that the essential condition occurring brittle - tough transition in such ternary system was l ? lc ( ? 0. 095 ? m ), and the effect of above factors on the impact behavior followed percolation mechanism which indicated that it was some reasonable using lc as single parameter criterion of brittle - tough transition of pp / eoc / caco3 composites. the micro - deformation model at different dispersing morphology was then proposed
首次將聚合物復合材料脆韌轉變機理的定量化研究從二元體系拓寬到三元體系，對ppffioc aco3體系的配方進行設計，制備得到高剛性高韌性低成本的聚丙烯復合材料， eoc和cvco3的體積份數之和為25v （其中彈性體相為10v 。It ' s significant to further the study of the environment evolvement and forming mechanism, and this helps to open out its ecological essential, protect and develop the oasis, lacated in the cross belt which converge northeaster and northwester, yutian oasis was threatened by the ilowing sand, and has the bad nature conditions the main purpose of the paper is applying fractal theory to research on the change of transitional belt between oasis and desert, which is a typical ecosystem in arid zone
而荒漠與綠洲之間的植被帶即過渡帶則最為敏感、完整地記錄了這兩大生態系統之間的相互作用與相互轉化，深入研究這一特殊地帶的環境演變過程、特徵及形成機制對于揭示其生態學實質、維護和發展綠洲具有重要的實踐意義。於田綠洲位於東北風與西北風的交匯地帶，受到流沙侵蝕的危害很嚴重，自然條件非常惡劣，生態環境異常脆弱，人民的生存環境受到了很大的威脅。Based on analyzing the achievement ' s foundation of country ' s enterprises development in our country, it is pointed out the problems of country ' s enterprises in developmental process, and it is put forwards reorganization mechanism and optimizing countermeasures of country ' s enterprises spatial development which evaluating industry guide, constituting reorganization policies, constructing groups mechanism, actualizing spatial reorganization and pushing rural urbanization
摘要在深入分析我國鄉鎮企業發展成就的基礎上，指出其中存在的問題，並提出生態脆弱區鄉鎮企業空間重組機制和重組對策：進行產業導向評價，制定重組政策，建構企業簇群，實施空間重組，有序推進農村地區城鎮化。And illustrates that the types of the crime of the network are : network hacker ; making and propagating computer virus ; network attacking and destroying ; network pornography ; etc. then analyses the reason why the crime of the network produces from three respects of internal, external cause and psychological factors, the internal cause refers to the fragility of network itself mainly ; then analyses some external causes such as the consciousness of network security is deficient, the safe mechanism of management lags behind ; and analyzes the psychological factors of subject emphatically : nihility of the crime sense, having idea of leaving things to chance, thin legal consciousnesses
繼而從內、外因及主體因素三方面分析了網路犯罪產生的原因，內因主要是指網路本身的脆弱性。在外因中分析了諸如經濟利益的驅使；網路安全意識欠缺，安全管理機制落後；規制網路犯罪的法制不健全，對網路犯罪打擊力度不夠；缺乏共同的國際標準等客觀因素，而且著重分析了主體的心理因素和意識因素即犯罪感的虛無化、存在僥幸心理、法律意識淡薄，從而找出了網路犯罪的「病因」 ，以便「對癥下藥」 。分享友人
