  1. 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橄欖巖、二巖、單斜石巖、純橄欖巖、方橄欖巖、石榴石二橄欖巖、金雲母二橄欖巖、榴巖;與中國東部以及華北地臺上地幔相,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73km ;從幔源重砂礦物的溫壓估算結果,可以推斷出巖石圈厚可達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。

  4. Such features can be ascribed to lower degrees of partial melting and greater melting depths. in particular, the decoupling between the lowest nag and highest tig tends to indicate residual jadeite during melting process so that na behaved as a moderately compatible element to lower the naao concentration in these rocks. this is consistent with the ree patterns in the high - ti diabases that have the highest ( gd / yb ) cn ratios than other two groups, which suggest a more important role of residual garnet in generation of the primary magmas

    運用mgo = 8進行標準化,結合巖石成因理論討論了三大系列綠巖的形成相對深和熔融例,其中高ti系列的原始巖漿形成深大,熔融例小,源區相對最為富集易熔組分;低ti系列的熔融深最淺,例最大,源區相對虧損易熔組分;過渡ti系列則介於前兩大系列之間。
  5. In the eme model, the electron energy balance equation is taken into account and the transport coefficients are assumed to be the functions of the electron mean energy. in this paper, a software is programmed to simulate the discharge process of plasma display cell of coplanar - electrode type, the matrix - electrode type and the novel shadow - mask pdp according to the gas discharge mechanism and fluid simulation theory. the simulation results show that both lfa model and eme model can be used to investigate the discharge characteristics of the cell, but the eme model is preferred for its better coincidence with theories and experiments

    在本文中,分別使用本地場近似的lfa ( localfieldapproximation )流體模型和假設碰撞反應系數、傳輸系數和電子的平均能量相關的eme ( electronmeanenergy )流體模型對pdp放電過程進行模擬,較分析模擬結果,得出eme模型和lfa模型對放電的繁流、起放電、熄滅等過程的描述的基本趨向是大致相同的,而從模擬工作電壓與實際電壓的接近程和放電效率角較, eme模型的模擬結果跟理論和實驗結果更為相符。
  6.
