熱裂煉 的英文怎麼說
中文拼音 [rèlièliàn]
熱裂煉
英文
thermal cracking-
Abstract : large time delay exists in complicated practical processes. for example, in fccu ( fluidized catalytic cracker unit ) reactor - regenerator, the feed is preheated through heat exchanging from fractional column slurry, thus results in large time delay. a predictive control system is designed for such processes, where the kernal algorithm is dynamic matrix control. application results show that the control behavior is improved than original pid control
文摘:實際的復雜工業過程，往往具有大的時滯，例如：煉油廠催化裂化裝置的反應再生系統，其原料油預熱通過油漿換熱實現，因此時滯特別大.本文針對這一類大的時滯過程，設計了以動態矩陣控制為核心演算法的預測控制系統，運行實踐表明：這一控制方案比原pid控制在控制質量上有較大提高This thesis also first presents the most straightforward and the most effective evaluation indexes on the qualities of crack filling and pothole repair, compares and analyzes the properties, the applicable situations, the strong and the weak points of crack filling materials ( such as hot asphalt cement, emulsified asphalt, modified asphalt, etc. ) and pothole repair materials ( such as hot - mix asphalt mixture and cold - mix asphalt mixture ). on the basis of the permanent demands on repair, this thesis sums up and lists the maintenance steps in crack filling and pothole repair, and advances the procedure designs to be directly adopted by maintenance workers of asphalt roads
首次提出了評定瀝青路面裂縫填封和坑槽修補質量好壞最為直接、有效的評價指標，分別對用作裂縫填封材料的熱瀝青、乳化瀝青和改性瀝青及用作坑槽修補材料的熱拌瀝青混合料和冷拌瀝青混合料的性能、適用場合及優缺點進行了比較分析，並按永久性修補要求，歸納提煉了裂縫填封和坑槽修補的工藝步驟，提出了可供瀝青路面養護人員直接採用的工藝方案。The intermediate pressure exhaust gas boiler in the shop of yantzi petrochemical oil refinery works is needed to recycle the exhaust heat from the dust
