中文拼音 [yùrèliàn]
預熱煉
英文
prebodying-
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The pressureless infiltration technique means that the spontaneous infiltration of the refined molten al or al - si alloy into the power bed, contains the filler reinforcement particle and k2tip4, occurred at 900 to fabricate sicp / al or sicp / al - si composites, without the aid of any externally applied pressure or vacuum, only by its gravity
無壓自浸滲法是指在不藉助任何外力作用下，把熔煉好的鋁液，經精煉，調溫后，澆入經過預熱，含有增強體顆粒與助滲劑的混合體粉末中。Beginning from the thermodynamics condition in the arc furnace and ladle, the anticipated goal was achieved by improving smelt process
