本文從氫燃料的物化特性和燃燒特徵著手,通過分析氫空氣混合氣燃燒的湍流火焰結構和燃燒化學反應動力學,基於雙區燃燒模型,建立了包括雙區熱力學、準維湍流卷吸燃燒、湍流火焰傳播速度、氫空氣混合氣燃燒化學反應動力學以及傳熱損失等模塊的燃燒模型,並給出了相應的計算方法。Microstructure of the composite layer was analyzed with help of optical microscope, scanning electronic microscope ( sem ), electronic probe microanalysis ( epma ) and x - ray diffraction ( xrd ). the compacting of the billet and the forming mechanism of the carbide reinforcement were studied based on thermodynamics and kinetics of reaction, sintering theory and the result of dta. at the same time, the wear - resistance of the composite layer was studied under condition of dry sliding friction
利用光學顯微鏡、掃描電子顯微鏡、電子探針以及x -射線衍射儀,分析了表面復合層的基體組織結構;運用反應熱力學、動力學、粉末燒結理論和燃燒合成理論,結合差熱分析結果,探討了表面復合層壓坯的燒結緻密化原理和碳化物增強相的形成機理;利用坯塊在真空燒結爐不同溫度下的燒結出來的顯微組織分析,模擬出坯塊的燒結過程中的化學反應過程。In addition, the enterprise offers sinter, gases, catalysts and catalysts
另外,公司也提供燒塊、燒結、熱防護、絕熱、熱絕緣以及催化劑。The microstructure of the polycrystal remains to be optimized to achieve good performance. to reduce the high cost and high - energy expedition of melting method, a solvothermal process followed by a sintering procedure of compacted pellets produced by using cold isostatic pressure method were mentioned to prepare polycrystalline samples of the ternary ( snte ) x ( bi2te3 ) y compounds
為彌補熔煉法高成本,高能耗等諸多缺陷,本文還採用溶劑熱法,成功合成了bi _ 2te _ 3和三元( snte ) _ x ( bi _ 2te _ 3 ) _ y化合物,並採用冷等靜壓成型,結合常壓燒結的方法制備塊體樣品。The speed became fast at the temperature 1050. the reaction could carry completely when billets was kept in vacuum tube for 3 hours " at 1050 temperature, under the striking of great quantity of heat when the molten iron poured into the mold, the reaction was blazed rapidly and continued at a high speed. the diffusible speed of v and c was very fast because the billet was heated over 1300 in a moment, so the reaction ca n complete in a few minutes
( 5 )碳化反應v + c vc在900左右開始發生,此時是固相反應,反應速度較慢,反應不能進行完全,隨溫度升高,該碳化反應的速度加快,在1050保溫3小時可以進行完全,在鑄造燒結時在過熱鐵水的巨大熱流密度沖擊下, v + c vc立即被激發,並以很快的速度進行,由於坯塊被加熱到1300以上,此時c和v擴散速度很快,因此鑄造澆注后的幾四川大學碩士學位論文分鐘內反應可以進行完全。分享友人
