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。The discuss starts from the " positive externalities " of tech - research and development, pointing out that the products of tech - research and development somewhat has the property of " public good ". without < wp = 8 > government ' s interfere, the intensity of tech - research and development by private section ca n ' t meet the need of " pareto optism " because of the " positive externalities ", as a result, the items of venture capital are insufficient and the development of venture captal will be pull back. rational policies of government expediture can internalize the " positive externalities " - transforming them to more revenue or less cost of the tech - research and development private suppliers. be feared of the high risk at the beginning of venture capital, the private section ca n ' t provide enough capital, the " capital gap " should be fetched up by government with equity capital, creditor ' s right capital, subcidy, at the same time, some other means, such as government purchase, credit guarantee, capital insurance, tax expenditure can promte private capital, is also important. in this part, the function of the above means, the establishment and enforcment of them are breafly discussed. because tax policies play a critical role in fiscal policy, r - y chart is used to analyse the relation between tax and venture capital, at last, a conclution is drawn : tax expenditure can promote venture capital
這部分論述從科技研發成果的「外溢性」入手，指出科技研發成果在不同程度上具有「公共品」性質，這種外溢性使得在純市場條件下，私人部門研發活動強度達不到社會資源配置最優的要求，也使風險投資項目來源不足， < wp = 6 >阻礙風險投資的發展。合理的政府財政支出政策可以使「外溢性」內部化。之後，論述了風險投資資本來源與政府財政支出政策的關系，由於風險投資尤其是其初期的高風險性，民間風險資本不足，應由政府以股權及債權投資、補助等財政直接支出方式彌補資本缺口，運用政府采購、財政擔保、保險、貼息、稅收優惠等間接支出方式，鼓勵民間資本進入風險投資領域也同樣重要。The results shows that the community richness, species diversity indices and evenness of tree layer and shrub layer share the same order, of which is higher in pure limestone region than that of in pure dolomite region, but it reverse in herb layer ; the coefficient of similarity is considerably low between all plots, while species turnover rate is quite high among the plots and is higher in dolomite region than that of in limestone ; in different karst regions, karst processing leads to niches diversity characterized by special morphologies and special element geochamical features, and therefore affect the dynamic and features of plant communities
我們在最有代表性之一的貴州茂蘭喀斯特森林保護區選取純灰巖和純白雲巖兩種巖性的喀斯特環境，對其元素地球化學特徵及其中原生性植物群落的相異性和物種多樣性進行了對比，結果發現：不同巖性區域多樣性：喬木層和灌木層為純灰巖區純白雲巖區，草本層為純白雲巖區純灰巖區，總體上純灰巖區的高於純白雲巖區的；各樣地間的相似性系數都很低，相同巖性類型內的明顯高於不同巖性類型之間的相似度；物種周轉率高，且白雲巖區高於石灰巖區，種類組成差異明顯；喀斯特區可溶巖地球化學背景通過喀斯特作用導致特殊的地形條件與元素地球化學特徵，並引起局部小生境的分異從而影響植物群落特徵。2. finite and infinite element coupling method applied in the paper can not only reflect the scattering phenomenon of waves, but also lessen the amount of calculation. it has significant advantage compared with pure finite element method
L本文的有限元一無限元耦合分析方法，不僅可以較好地反映波在無限域介質中的能量彌散現象，同時大大減小了計算量，與單純的有限元法相比，具有顯著的優越性。Variational image sampling was employed for focus windows selection, and the harmony between resolution and field of view was implemented. a human face extracting method based on color, shape and detail features was proposed, in order to overcome restriction of method based on skin detection. a method using optical flow was introduced to segmenting moving human face in focus images, and has better perspective in surveillance situation
我們從多方面進行探討，提出用統計手段分析成像主體最可能被放置的區域，有效地減少了成像主體不在中心時引起的誤對焦；提出用解析度空間變化的手段對圖像進行非均勻采樣，達到解析度與視場的協調；提出通過顏色、形狀和細節三方面進行人臉探測，有效地克服了單純靠皮膚進行探測的局限：提出基於光流場的方法分割圖像中的人臉，適用於監控場合。The development of science and technology journal is limited obviously by its circumstance such as region, contribution, reader, etc. under the influence of these conditions, the confined mind and the unenterprise attitude is produced by editors. thus, the weak link of developing science and technology journal is showed conspicuously in blazing new trails of content, expanding circulation, and founding famous brand. for expanding the developing space of science and technology journal, some effective measures should be adopted. first, the content and quality of journal should be highly valued. the constantly bring forth new ideas in the content should be promoted by publishing original theses, supporting new subject, introducing new direction, creating characteristic column, etc. by means of these methods, the aim of spreading original achievement, starting new fields of scientific research can be achieved. so academic standard and effect of the journal can be improved. second, the operate mechanism of journal as a processing workshop should be changed. the varied methods should be adopted for selling, circulating and information feedback of journal. third, the reputation of the journal should be safeguarded by correcting ideology of publish. the resources of the journal should be rationally used and developed. it can promote the science and technology journal growing continued
科技期刊的發展受到地域、稿源、讀者等環境因素的制約.受其影響，編輯易產生封閉、不思進取的心態，使科技期刊在內容創新、擴大流通、創立品牌等方面突現出薄弱環節.為拓展科技期刊的發展空間，首先應抓內容和質量，通過刊發創新論文、扶持創新學科、引進創新方向、創辦特色欄目促進科技期刊內容創新，以傳播創新成果，開辟創新領域，提高期刊的學術水平，擴大影響力;其次，應改變純粹的生產單位、加工車間的運作機制，採用多種局道、多種方法加強科技期刊出版后的營銷、流通及信息反饋等工作，走出重生產、輕開發、輕流通的誤區，擴大影響面;第三，應端正出版理念，維護刊物的聲譽，合理利用、充分拓展科技期刊的品牌資源，促進科技期刊的可持續發展分享友人
