Research progress of interactive influence and thresholds of geographic environmental elements on sediment yield of drainage basins in the middle reaches of the yellow river basin 黃河中游侵蝕產(chǎn)沙環(huán)境要素臨界與交互作用研究進展
We successfully apply the two - fluid model ( tfm ) to the study of two dimensional and three dimensional dense gas - solid flow characteristics . the results show some rules on the particle collisions and gas particle interactive influence of the vertical upward pipe 在對高濃度氣固兩相流的研究中,成功的運用雙流體模型對兩維和三維垂直立管段進行了研究,揭示了垂直立管內(nèi)的高濃度氣固流動的顆粒碰撞以及氣相和顆粒相的相互影響的一些規(guī)律。
And the interactive influence of the coaxial diffraction wave components during reconstruction can be eliminated completely by phase - shifting method . this in - line phase - shifting digital holography has been applied to three dimensional microscopy , non - contact measurement , pattern recognition and surface contouring 這種同軸相移數(shù)字全息技術(shù),可以廣泛應用于小尺度三維形貌的快速測量、數(shù)字無損干涉計量、圖像識別、顯微成像等領(lǐng)域。
Treating the soil as a two - phase mixture and considering the interactive influence of seepage and solid deformation , this paper analyzes the dynamic impedance of group piles in layered saturated porous media by indirect boundary element method and investigates the effects of pore fluid in saturated soils on dynamic impedance of piles 摘要將飽水軟土地基視為兩相介質(zhì),考慮水的滲流和土骨架變形的耦合作用,用間接邊界元法分析層狀飽水軟土地基中橫向受荷群樁動力阻抗,探討飽和土中孔隙流體對飽和土中橫向受荷群樁動力阻抗的影響。
On the base of the study of dense gas - solid flow , we make full - scale numerical simulation on the combustion and pollutant emission processes of the 75t / h circulating fluidized bed ( cfb ) which is developed by our institute . we draw the conclusion on the characteristics of flow field , particle track , temperature profiles and species profiles . we also study the characteristics of coal combustion and nox formation and the interactive influence between them 在對高濃度氣固兩相流動的系統(tǒng)研究基礎上,針對我們熱能所研制開發(fā)的75t h循環(huán)流化床熱電氣三聯(lián)供裝置,首次對于流化床燃燒爐內(nèi)的燃燒和污染物排放進行了較全面的數(shù)值模擬,得出了爐內(nèi)的流場、顆粒軌跡場、溫度場和組份場,研究了煤粉燃燒特性和氮氧化物的排放特性以及影響它們的因素。
