1关于BL-代数的模糊滤子与模糊理想(英文)显示文摘在BL-代数中引入模糊超滤子和模糊固执滤子的概念,证明了如下条件对于BL-代数的非常数模糊滤子f来说是等价的:(1)f是布尔的和素的,(2)f是蕴涵的和素的,(3)f是超的,(4)f是固执的。应用模糊正蕴涵滤子给出G-代数的若干特征性质。提出BL-代数模糊理想的概念,给出一些重要例子,并通过例子说明在BL-代数中模糊理想一般不能由模糊滤子导出。同时,从模糊理想出发构造了商BL-代数,并建立了相应的同态基本定理。最后,研究了BL-代数的几类模糊理想及其相互关系,给出模糊布尔理想、模糊素理想、模糊超理想的特征性质。张小红 Jun Young Bae Doh Myung Im 2006模糊系统与数学2006,20,3:27
2反向的民主化:第三波民主的问题显示文摘第三波民主化浪潮中的国家,多在建立法治、公民社会、领导人问责制等现代国家的基本制度之前建立了自由选举制度。相反,第一波民主化的国家则在普选引入之前已经先建立了现代的国家制度。第三波民主化中这种反方向的民主化造成了在大多数国家中形成的是不完全的民主制度。不完全的民主有三种发展前景:(1)继续向前,完成民主化;(2)民主选举制度失败,转向一种不民主的制度;(3)在统治精英低效但公众对民主政治要求也低的情况下,更会堕入一种低水平平衡的陷阱。本文通过分析三个新民主国家的大众观念调查数据,展示这样一种不完全民主的各种问题。这三个国家的前身各不相同:过去属于专制体制的俄罗斯、过去曾有民主和专制的捷克、过去是专制军事政权的韩国。Richard Rose Doh Chull Shin 王正绪 方瑞丰 2007开放时代2007,,3:16
3Temperature Distribution and Thermal Stresses in Various Conditions of Moving Heating Source during Line Heating Process显示文摘Line heating method is widely used to manufacture curved surfaces in ship building. The main factors governing the quality of the manufactured products are the moving velocity of the heating source, heating strength, and heating ways. In this study, the temperature distributions of the heated plate were investigated with the condition that the line heating process was automatic. The temperature variations were also investigated with the changes of those three variables. The numerical results showed that the peak temperature decreased as the moving velocity of the heating source increased. It also revealed that the peak temperatures changed linearly with the changes of the heating source.Yoon Hwan Choi Yeon Won Lee Kwang Choi Deog Hee Doh Kyoung Joon Kim 2012Journal of Thermal Science2012,21,1:10

5Performance Improvements in Temperature Reconstructions of 2-D Tunable Diode Laser Absorption Spectroscopy(TDLAS)显示文摘Performance improvement was attained in data reconstructions of 2-dimensional tunable diode laser absorption spectroscopy(TDLAS). Multiplicative Algebraic Reconstruction Technique(MART) algorithm was adopted for data reconstruction. The data obtained in an experiment for the measurement of temperature and concentration fields of gas flows were used. The measurement theory is based upon the Beer-Lambert law, and the measurement system consists of a tunable laser, collimators, detectors, and an analyzer. Methane was used as a fuel for combustion with air in the Bunsen-type burner. The data used for the reconstruction are from the optical signals of 8-laser beams passed on a cross-section of the methane flame. The performances of MART algorithm in data reconstruction were validated and compared with those obtained by Algebraic Reconstruction Technique(ART) algorithm.Doo-Won Choi Min-Gyu Jeon Gyeong-Rae Cho Takahiro Kamimoto Yoshihiro Deguchi Deog-Hee Doh 2016Journal of Thermal Science2016,25,1:8
6标准养护下CaO-粉煤灰地聚物制备及微观研究显示文摘在标准养护下,向粉煤灰中掺入适量CaO制备粉煤灰基地质聚合物。结果表明,加入CaO在早龄期会使抗压强度出现下降,养护7d后抗压强度随CaO掺量增加出现先增大后减小的趋势,最优nCa/nSi为0.18。粉煤灰玻璃球中的硅铝相经历了解聚-聚合的过程,体系中水化硅酸钙(C-S-H)凝胶和地质聚合物凝胶(N-A-S-H/C-A-S-H)共存,水化产物为无定形结构,无新的结晶相生成。CaO过量(nCa/nSi>0.18)时,Ca(OH)2及CO32-的存在会对材料抗压强度产生不利影响。毛明杰 马明晓 ShuIng Doh 杨秋宁 2020非金属矿2020,43,4:8
7Preparation of AZ91D Slurries for Semi-Solid Forming Using Al8 ( Mn, Fe) 5 Precipitates显示文摘During the solidification of the AZ91D-alloys, the Al8(Mn, Fe)5 phase is generally precipitated in the melt in advance of the precipitation of the primary α-Mg. The basic principle for manufacturing AZ91D-alloy slurries for semi solid forming is to use the Al8(Mn, Fe)5 precipitates as the heterogeneous nucleation sites for primary α-Mg phases. Microscopic analysis for the location of the Al8(Mn, Fe)5 precipitate explains that the Al8(Mn, Fe)5 precipitate is the effective heterogeneous nucleation site for the primary α-Mg phase. It was also observed that increase of the Mn content in the melt and the cooling rate below to the solid/liquid two-phase region resulted in smaller and more globular primary α-Mg due to the increase of heterogeneous nucleation sites. It was found that the average α-Mg diameter grew as a function of t0.278, where t is the holding time at the solid/liquid two-phase region. This would be attributed to the Ostwald type ripening and coalescence between primary α-Mg phases. The cooling rate below to the solid/liquid two-phase region, Mn content in AZ91D alloy, and the holding time and temperature affected on the quality of slurry.Ji Young Byun Soon Il Kwon Jeong Man Doh Heon Phil Ha 2004Journal of Rare Earths2004,22,z2:4
8Cu^+-incorporated TiO_2 overlayer on Cu_2O nanowire photocathodes for enhanced photoelectrochemical conversion of CO_2 to methanol显示文摘In this paper, we report photoelectrochemical(PEC) conversion of carbon dioxide(CO_2) using photocathodes based on Cu_2O nanowires(NWs) overcoated with Cu^+-incorporated crystalline TiO_2(TiO_2–Cu^+ )shell. Cu_2O NW photocathodes show remanent photocurrent of 5.3% after 30 min of PEC reduction of CO_2.After coating Cu_2O with TiO_2–Cu^+ overlayer, the remanent photocurrent is 27.6%, which is an increase by5.2 fold. The charge transfer resistance of Cu_2O/TiO_2–Cu^+ is 0.423 k/cm2, whereas Cu_2O photocathode shows resistivity of 0.781 k/cm2 under irradiation. Mott–Schottky analysis reveals that Cu^+ species embedded in TiO_2 layer is responsible for enhanced adsorption of CO_2 on TiO_2 surface, as evidenced by the decrease of capacitance in the Helmholtz layer. On account of these electrochemical and electronic effects by the Cu^+ species, the Faradaic efficiency(FE) of photocathodes reaches as high as 56.5% when TiO_2–Cu^+ is added to Cu_2O, showing drastic increase from 23.6% by bare Cu_2O photocathodes.Kangha Lee Seokwon Lee Hyunjin Cho Sunil Jeong Whi Dong Kim Sooho Lee Doh C.Lee 2018Journal of Energy Chemistry2018,27,1:3

10Effects of feeding tyrosine and phenylalanine on the accumulation of phenylethanoid glycosides to Cistanche deserticola cell suspension culture显示文摘AIM: To investigate the effects of feeding phenylalanine(Phe) and tyrosine(Tyr) on the accumulation of total phenolic compounds and four phenylethanoid glycosides(PeGs) to a cell suspension culture of the parasitic plant Cistanche deserticola. METHOD: A cell suspension culture of C. deserticola was established and precursors of different concentrations were fed. In each group, the cell was sampled at the 24th day after inoculation. The content of total phenolic compounds and four PeGs compounds were determined using the Folin-Ciocalteu method and an HPLC method, respectively. RESULTS: In the Phe fed cells, the maximum PeGs yield was achieved when Phe was fed at 1.5 mmol·L-1 and the yield reached 1.13 times the control cell concentration. In the Tyr fed cells, the maximum yield of PeGs was 1.60 times of control when 0.75 mmol·L-1 Tyr was fed to the cells. Furthermore, it was found that the salidroside yield was 4.01 times of control group when 5 mmol·L-1 Tyr was fed. CONCLUSION: Tyr is a better precursor for PeGs accumulation compared with Phe, and the rate limiting enzymes might be involved in the Tyr branch.HU Gao-Sheng JIA Jing-Ming Doh Hoon Kim 2014Chinese Journal of Natural Medicines2014,12,5:2
