中文拼音 [zuìdīzhāohuǒnéng]
最低著火能
英文
minimum ignition energy-
Moreover, the system of powdered coal conveying with primary air is the most important tache, whether the distribution of primary air is even or not directly relates to whether the distribution of powdered coal is even or not in all firing implement and nozzles, sequentially directly relates to whether it is hard to take fire, whether the fire is stable, whether there is coking and how about the heat efficiency of the boiler, hi addition, if there is jamming and deflagrate in the system of powdered coal conveying with primary air, severe safety accident can be resulted
良好的煤粉配風是建立合理的爐內空氣動力工況和穩定燃燒的必要條件。而其中一次熱風送粉系統又是最重要的一個環節，一次風配風是否均勻直接關繫到煤粉在各燃燒器和各噴嘴中的分佈是否均勻，從而直接關繫到著火是否困難、火焰是否穩定、局部是否結焦以及鍋爐的熱效率高低。若一次風送粉系統發生堵塞和煤粉爆燃則可能引發嚴重的安全事故。All that she could at first distinguish of them was one syllable, continually repeated in a low note of moaning, as if it came from a soul bound to some ixionian wheel -
她最初能夠分辨出來的只是一個音節，用一種低聲呻吟的調子不斷重復著，彷彿是綁在伊克西翁火輪上的靈魂發出的聲音Results of the experiments showed that the wear mechanisms of the sintered steel included abrasive wear, adhesive wear and fatigue wear, and it was the abrasive wear most important. it was the sintered steel mixed by ni, mo that was the best on the wear resistance, because of the great lot of bainite ; the sintered steel quenched and low temperature tempered mixed by mo, w that was the best on the wear resistance, because of the rigidity of the steel was the highest
實驗結果表明：本文中幾種燒結鋼的磨損機制均是由磨粒磨損、粘著磨損、和疲勞磨損共同作用的，且以磨粒磨損為主；在燒結態下，復合添加合金元素鎳、鉬的燒結鋼的耐磨性能最好，這是因為生成了大量的硬質相貝氏體；而淬火、低溫回火態下，則復合添加鉬、鎢的燒結鋼的耐磨性能最好，這是因為熱處理態下添加鉬、鎢的燒結鋼的硬度最高。The experimental results indicates that the secondary mass flow increases with increasing of primary mass flow rate, but the bypass decrease because the primary mass flow rate increase more rapidly than secondary mass flow. the expansion configuration shows low thrust property due to low pressure in flow path. the secondary nozzle changes the pressure distribution in ejector combustor, and decreases bypass ratio, but obtain more completely mixing
結果表明：二次流流量隨著一次流流量的增加而增加，由於二次流流量的增加速度低於一次流，引射系數減小；在純擴張式結構實驗中，引射燃燒室壓強很低，難以實驗推力增強；二次噴管改變了引射燃燒室的壓強分佈，降低了引射系數，改善了混合狀況能；對于本文的實驗結構，存在一個最優的二次噴管出口面積，使引射火箭推力最大，同數值模擬結果相吻合。The main results are : supersonic region and subsonic region can co - exist in flow path simultaneously, subsonic flow is insignificance for engine performance ; total pressure of primary rocket should be decreased when mach number is increased. in the experimental aspect, some components of ejectorjet experimental system were improved, ejectorjet experiments using alcohol as secondary fuel were conducted
由數值計算獲得的結論為：引射火箭內的一般流態為超音速區與亞音速區共存，亞音速區不具備做功能力；飛行馬赫數增大，引射火箭內更易於產生壅塞；為了獲得最佳的性能，隨著飛行馬赫數的提高，應當降低一次火箭的工作壓強。Abstract : according to time - sharing price counting policy of electricpower, the relationships of current density and current efficiency at different ratios of sulfuric acid and zinc are obtained through analyzing process data of electrolytic zinc process ( ezp ), and an optimization model of time - sharing power supply dispatching system ( tpsds ) of ezp is established. an single - loop simulated anneling algorithm with mutation and variable searching spaces is proposed and applied to the tpsds to obtain optimal time - sharing power supply scheme. industrial practical results show that the optimal dispatching system can greatly decrease the power consumption of ezp and increase the time - sharing profits
文摘:依據電力部門的分時計價政策，根據由生產過程數據所建立的不同酸鋅比下電流密度與電流效率間關系，建立鋅電解過程分時供電優化模型.同時，提出一種帶變異操作和變搜索空間的單循環模擬退火演算法，並將該演算法應用於分時供電優化調度，獲得最優的分時供電方案.工廠運行結果表明：整個優化調度系統能顯著降低鋅電解過程的電耗並增加分時效益分享友人
