Compared with sputter crater depth results measured with surface profilometer, the converted depth results obtained by gd - oes were accurate and credible
輝光光譜定量轉化所得深度結果與表面形貌儀剛定相應濺射坑的深度結果對比發現，本方法定量轉化深度結果準確可靠。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輝綠巖的形成相對深度和熔融比例，其中高ti系列的原始巖漿形成深度大，熔融比例小，源區相對最為富集易熔組分；低ti系列的熔融深度最淺，比例最大，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。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，比較分析模擬結果，得出eme模型和lfa模型對放電的繁流、起輝放電、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度和放電效率角度比較， eme模型的模擬結果跟理論和實驗結果更為相符。The influence of chroma is investigated on physical compound of long - persistent red phosphor and strontium aluminate phosphors doped with eu2 + is investigated. lt is found that the long - persistent white phosphor can be acquired when red phosphor and strontium aluminate phosphors are mixed with molar proportion of 100 : 20
研究了紅色磷光體與摻eu鋁酸鹽磷光體的物理復合及對色度的影響，實驗發現紅色磷光體與鋁酸鹽磷光體按100 ： 20比例混配可獲得接近白色長余輝磷光體。分享友人
