    随着社会和经济的不断发展,可以生产小批量、多种类、高附加值产品的间歇生产过程在现代化工业过程中发挥的作用越来越重要。为了提高生产效率和产品质量,如何进行间歇过程的有效建模,并在过程模型上施加控制策略从而提高其自动化水平迫在眉睫。针对大多数间歇过程动态的快时变性和强非线性,人们很难在有限的时间和资金投入下建立精确可靠的机理模型,所以经常采用基于数据的系统辨识方法来建立过程模型。但直接利用传统辨识算法一般难以取得满意的辨识结果。注意到间歇过程是一个重复性过程,可以借鉴迭代学习控制思想,通过批次到批次不断修正过程模型来获得辨识模型的不断改进,这种辨识思想称为迭代辨识。本论文提出采用多维时间的迭代学习...With the development of economy and society, batch process, which can flexibly manufacture small-volume, various style and high value-added products, plays more and more roles in the modern industry. In order to improve the product quality and the process efficiency, process modeling and control for batch process have attracted more and more attentions. Considering the significant time-varying and...学位:工学硕士院系专业:化学化工学院_工程硕士(化学工程)学号:2062013115147

    [中文文摘]用高速碰撞共沉淀法制备m(CuO) /m(ZnO) /m(Al2 O3 )比分别为 60 /3 0 /1 0和 3 0 /60 /1 0的 1 #和 2 #催化剂 ,结果表明高ZnO的 2 #催化剂活性较好 ,分散度较大。XPS测试表明 2 #催化剂表面ZnO吸附的中间体 (CHx 或CHxO)较多且表面的Cu+1浓度较高 ,从而促进CO加氢合成甲醇的活性。[英文文摘]Cu/ZnO/Al_2O_3 catalysts with ratios of 60/30/10 and 30/60/10 have been prepared by high speed collision coprecipitation method. The performance of the catalyst with the higher ZnO content shows the higher activity in methanol synthesis. The characterization results indicated that the catalyst with the higher ZnO content has higher dispersion. On the surface of the higher ZnO content catalyst, there was more Cu+1 and more intermediate (CH_x and CH_xO) adsorpted. It is beneficial for the CO hydrogenating to produce methanol

    Serum beta 2-microglobulin in spinal cord injury patients--its efficacy as a screening test of renal function

    Get PDF
    We evaluated the reliability of serum beta 2-microglobulin (beta 2-MG) in comparison with serum creatinine, blood urea nitrogen and creatinine clearance in 164 patients with spinal cord injury. The value of serum beta 2-MG demonstrated the highest correlation coefficient (r = -0.927) in relation to creatinine clearance. The beta 2-MG value reflected the severity of hydronephrosis on excretory urography, with very few false negative values. The value of beta 2-MG is concluded to be one of the best screening tests in evaluating renal function in spinal cord injury patients
