Secondly, based on the microbeam analytical technique, on the one hand, through investigating the characteristic of major elements in the mantle minerals the author acquired the static information from mantle ; on the other hand, through multi - point analysis of a part of the minerals from mantle, the auther got dynamic information from mantle. finally, generalizating the fruits of this study and predecessors, the autor holds that the constituents of lithospheric mantle possibly includes spinel lherzolites, clinopyroxenites, websterite, dunite, harzburgites, garnet lherzite, phlogopite lherzite, eclogites, clinopyroxene megacrysts ; compared with east china and north china platform, the research field mantle shows the characteristics of higher degree of partial melting processes and more depleted mantle ; the. upper mantle beneath north hetian area is heterogeneous, with a tendency of deficit in a12o3 and lree from kaliyang in west hetian to the river basin of kalakshi river and yulongkashi river ; the subduction of the crust beneath north hetian has ever occurred in geological history and caused the mixing of mantle - crust ; the depth of the origination of basaltic magmas beneath north hetian exceeds 73km ; the thickness of the lithosphere beneath the research area amounts to 204. 9km ; the mantle beneath north hetian has geological condtions for forming diamond deposits
最後，綜合本區幔源礦物和地幔巖石的特徵以及地球物理資料，得出如下結論：本區上地幔的物質組成有尖晶石二輝橄欖巖、二輝巖、單斜輝石巖、純橄欖巖、方輝橄欖巖、石榴石二輝橄欖巖、金雲母二輝橄欖巖、榴輝巖；與中國東部以及華北地臺上地幔相比，研究區上地幔具有富集主元素中相容元素和虧損其中的不相容元素的特徵，局部熔融程度較高；上地幔存在橫向和縱向的不均一性，從西部的克里陽到喀拉喀什河和玉龍喀什河流域， al和lree富集程度呈下降趨勢，不同來源的相同礦物中主元素的含量差異較大；地質歷史時期這里可能發生過地殼俯沖並產生殼幔混合作用；玄武巖漿的起源深度73km ；從幔源重砂礦物的溫壓估算結果，可以推斷出巖石圈厚度可達204 . 9km ；綜合巖石圈物質組成特徵、巖石圈熱狀態、地幔溫壓狀態、氧逸度以及幔源巖石和幔源礦物的化學成分，認為研究區具備了金剛石成礦地幔地質條件。This paper analyzes the percolation mechanism and characteristics of gas under low - velocity percolation state in terms of slippage effect and threshold pressure effect by using molecular dynamics, thermodynamics and percolation mechanics in order to understand the practical reason of low - velocity non - darcy percolation
摘要為明確氣體在低速滲流狀態下的滲流規律以及產生低速非達西滲流的實質性原因，運用分子動力學、熱力學和滲流力學等相關知識，基於滑脫效應和閾壓效應兩方面分析了氣體在低速滲流狀態下的滲流機理及滲流特徵。In order to resolve these problems, we have made thorough studies about the research achievements on the teacher employment at home and abroad ; about the successful experiences of the developed western countries such as the united states of america and the great britain as well as about the successful practices carried out by the schools in the developed cities in china. based on the thorough studies, we have put forward our conceptions about the further reform of the teacher employment system carried out in the primary and middle schools in the rural regions. that is, the conception about the aims for the reform ; the conception about the contents for the reform and the conception about the model - the dynamic full contract employment system
針對目前農村中小學教師聘任制改革過程中存在的問題，通過研究國內外教育家有關中小學教師聘任制方面的研究成果，西方美英等發達國家中小學實施教師聘任制的成功經驗以及中國發達地區中小學實施教師聘任制的改革實踐，本文提出了農村中小學深化教師聘任制改革的階段性目標、深化改革的內容、教師聘任制的模式? ?動態全員合同聘任制，以及推行教師聘任制的配套改革：全面實施教師資格證書制度是推行動態全員合同聘任制的條件；實施教師人事代理制是推行動態全員合同聘任制的難點；教師職務評聘分開是推行動態全員合同聘任制的重要環節；公式撥款、工資總包干是推行動態全員合同聘任制的關鍵；完善社會保障體系是推行動態全員合同聘任制的重要保障；分析了深化改革過程中骨幹教師流失的原因並提出了解決這些問題的對策。The main problems existed are as follows : the limited basic facilities in logistics ; the out - dated management system, piece partition ; the poor low service level, limited scope ; the backward concept in logistics, the lack of talented people, the deterioration of the ecological environment in some parts of the area, and the traffic problems, etc. but, on the other hand, the development in western logistics also has the advantages which the eastern logistics does not possess, including the resources, regional and potential advantages
西部物流發展中存在的主要問題是：物流基礎設施薄弱；管理體制陳舊，條塊分割；物流企業服務層次低，規模小；物流觀念滯后、人才缺乏，另外還有部分地區存在生態環境惡化、交通不發達等制約因素。另一方面，西部物流的發展也具有東部物流所不具有的優勢，包括資源優勢、區位優勢和后發優勢，即將建成的鐵路、公路聯運和通江達海聯運大通道也給西部物流的大發展提供了有利的條件。分享友人
