目的:在全球所有的合成树脂中,聚烯烃的产能位居榜首,在国民经济建设和社会发展中发挥着重要作用。但流化床聚合反应器内的高静电会引起颗粒团聚,一旦传热受阻,颗粒极易熔融结块,甚至导致装置爆聚停车。本研究旨在针对流化床聚合反应过程具有强放热、高静电、变粒径的特点,提出基于声发射技术的多种检测手段和信息提取方法。创新点:针对聚合过程的爆聚结块问题,本研究主要解决了以下难题:(1)流化床内颗粒和结块的原位表征技术缺失,难以检测;(2)颗粒熔融结块过程的在线干预机制不清楚,难以调控;(3)流动传热过程强耦合,反应器放大规律不明,导致反应器难放大等问题。方法:创立声发射信号的多尺度解析方法,通过小波分解和重标极差分析法分类重构将声发射信号分解为微尺度、介尺度和宏尺度信号;提出基于声发射检测的反应器操作优化技术,并通过建模确立流化床聚合反应器的时空产率数学模型。成果:新技术成功应用于"十一五"国家重点建设项目——天津百万吨乙烯工程相配套的年产30万吨气相法聚乙烯流化床反应器的设计建设。并且,新技术已成功应用于14套大型聚烯烃装置的设计或改造,所涉及的聚乙烯产能达263万吨。作者所在团队也因该技术发明获得了2016年度国家技术发明奖二等奖。

An iterative partial transmission sequence （IPTS） cascading time-delay neural network （TDNN） scheme is proposed to reduce peak-to-average power ratio （PAPR） in the coherent optical orthogonal frequency division multiplexing （CO-OFDM） systems. The IPTS algorithm further reduces computational complexity based on the partial transmission sequence （PTS） algorithm. TDNN is trained by the iterative clipping filtering （ICF） method. Simulation results show that the proposed scheme achieves a PAPR reduction of 5.84 dB when complementary cumulative distribution function （CCDF） is 10-4and an extra transmission distance of 200 km for 10-3bit error rate （BER） compared to the original signals.

In the intricate process of natural product biosynthesis, a metabolon can enhance metabolic flux by associating sequential enzymes. A fungal metabolon, comprising of flavin-dependent monooxygenase Spe F and P450 monooxygenase Spe G, is identified in the biosynthesis of spiro polycyclic alkaloids(+)-notoamide B and its diastereomer(+)-versicolamide B. Using notoamide E as a substance, Spe F/Spe G metabolon can control the stereoselectivity of its 2,3-epoxidation, followed by hydrogen atom ion at C-17 to generate reactive epoxide tau-m A with dienyl iminium unit. Subsequently,(+)-notoamide B and(+)-versicolamide B are produced via tandem nonenzymatic inverse-electron-demand Diels-Alder reaction and semipinacol rearrangement. This provides the first example of metabolon in the biosynthesis of spiro-prenylated indole alkaloids.

This study constructed a mathematic model of a variable frequency centrifugal chiller using Simulink software. By running the simulation, it was discovered that when the other factors are constant, the EER(Energy Efficiency Ratio) of the chiller increases with decreases in the temperature of the cooling water and increases in the temperature of the chilled water. The effect of changes in the cooling water temperature on the EER of the chiller is stronger than that of changes in the chilled water temperature. In addition, as the chiller load decreases, the EER increases until reaching a maximum, after which it decreases. Furthermore, the EER of chillers working under a constant flow rate is slightly higher than that of those working under varying flow rates.

As a class of functional crystalline porous materials, metal-organic frameworks(MOFs) gained rapid development in the past three decades and a large number of MOFs with ordered structures, high surface areas, and functionalized channels have been investigated. MOFs and MOF-derived/composite materials show great potential in many application fields. In this review, we discussed the main applications of MOFs and MOF-derived/composite materials in small molecule storage, separation, luminescence, sensing, multitype catalysis, and energy storage. In addition, challenges and problems in the future research of MOFsrelated fields are also discussed.
