Abstract : the distribution of cooling air which is in the grille - brick of the inner combustion hot air stove has been simulated with three dimension turbulent mathematical model so as to find a method which is used to improve the distribution of cooling air in hot air stove. the influence of differential horizontal plates on the distribution of cooling air is discussed. the results show that original big circle round field of flow in the pillar - cavity is changed into full one - way field of flow and edges gas flow, at the same time, is increased by horizontal plates. there is a different function with horizontal plates and vertical plates. to make the uniform distribution of cooling air in the hot air stove, it is necessary that horizontal plates and vertical plates are used in a combined way
文摘:應用紊流三維數學模型模擬內燃式熱風爐內冷風在格子磚柱中的分佈,尋求改善其分佈的途徑.討論了加設不同布置的水平導流板對氣流分佈的影響.模擬結果表明,在支柱空腔內加設水平導流板改變了原有大迴旋流場,使迴旋流變成大面積的單向流.通過在支柱空腔內加設水平導流板可以發展邊緣氣流,這恰好與加設豎直導流板的作用相反,水平導流板和豎直導流板的結合使用有望實現冷風在格子磚柱中的均勻分佈The results are as follows : as the sputtering pressure increases, the atomic ratio of o to ti increase in the films, which is attributed to the fact that the absolute oxygen content increases, as the pressure increases despite the ratio of 62 to ar remains unchangless
結果發現:在氧氣、氬氣分壓比不變的條件下,薄膜表面o和ti原子比增大,這可能是由於濺射氣壓增大,而氧氣與氬氣比未變,真空室中氧氣的絕對含量增加,參加反應的氧原子數增加的緣故造成的。In the second place, based on the asu of buggenum igcc plant in netherlands, both static and dynamical model for distillation tower of the asu are created and some valuable conclusions are gained as well. finally, a compartmental simplified model is created for distillation tower of the asu, in order to reduce the simulation time and increase the simulation efficiency. the new model will be helpful to the further simulation and on - line optimal control for the asu of the igcc plant
其次,本文以荷蘭buggenum電站的空分系統為原型,基於matlab建立了空分系統精餾塔的半圖形化動、靜態數學模型,並通過模擬,得出了一些有價值的結論:當空分系統的壓力變化時,氧氣產品濃度的響應時間常數為兩小時左右,說明空分系統是igcc電站最大延遲環節;而且雖然氧氣濃度最後會穩定在igcc電站所要求的范圍之內,但在過渡過程中會超出限制,這些都為igcc電站的安全運行及控制系統設計提供了有價值的信息。Because of the existence of the holes in the system, the molecular fraction q should considered into the free energies and the gibbs functions. when there are few holes or none existing in the system, i. e., it corresponds to the liquid state or solid state ; when there are lots of holes and a few atoms existing in the system, i. e., it corresponding to the gas state
為了進一步研究固、液、氣三相之間的轉變,我們引入空格點並定義了占據率q ,當空格點幾乎沒有或很少時,即q 1 ,系統對應的是固態或液態;而當空格點很多時,即q 0系統中原子很少,系統對應的則是氣態。The spontaneous reduction of ni3 + to ni2 + is considered to the actual origin of chemical instability of linio2 during storage. the corresponding oxidization of lattice oxygen o2 " to active oxygen species ( o -, o2 - ) is thought to the direct cause of formation of li2co3 and adsorption of h2o and co2 on the surface of stored materials
Linioz電極材料中自發的ni3 + * ni2 +還原過程被認為是其貯存期間性能變質的產生根源,與之相對應的氧負離子生成活性氧物種則是電極材料表面形成lizc03及其它吸附物種的直接原因,而空氣中的coz和hzo促進了整個氧化還原反應的進行。Successfully applied markov process to analyze the change of vegetation cover, and point out the change of vegetation transition is not a single markov process but a multi - markov process and also is a long term process. 9. the writer proved that under the 8km resolution, the markov process ca n ' t estimate the trend of land use by two term - data no matter it ' s sequence or at intervals. through analyzing the change of each vegetation area, the change of spatial data and the markov process, the main conclusions are : in plain of china western arid land, the desert area decreased and the oasis area increased, most of the increase represents extension of the traditional oasis
利用回歸方程對今後的植被變化情況進行了模擬預測,其結果具有一定的參考價值;南京氣象學院博士學位論文8 .將馬爾科夫過程成功地應用於中國西部干早區的植被變化分析當中,指出,植被的轉移變化不是一重馬爾科夫過程,而是一個多重的馬爾科夫過程;而且是一個步長較長的馬爾科夫過程; 9 .證明在8klll尺度下,馬爾科夫過程不能使用兩期的土地利用變化來預測土地利用的發展趨勢,無論這兩期的時間是連續的還是有一定時間間隔的;通過各類植被的面積變化、空間變化及馬爾科夫過程分析認為:中國西部乾旱區在平原區整體上荒漠面積減少,綠洲面積增加,綠洲的面積擴大主要表現在原有綠洲的擴大。分享友人
