The orientation of HDTMA+ in the interlayer of organic pillared montmorillonites prepared at different concentrations of HDTMA+ have been studied using X-ray powder diffraction (XRD) and theoretical calculation. A series of arrangement models of HDTMA+ in the interlayer of montmorillonite have been proposed as lateral-monolayer (LM), lateral-bilayer (LB), pseudotrilayer (PT), paraf-fin-type-monolayer (PM), paraffin-type-bilayer (PB). With the increase of the concentration of HDTMA+, the arrange-ment model of HDTMA+ in the interlayer of montmorillo-nites changes as lateral-monolayer→lateral-bilayer→para- ffin-type monolayer→pseudotrilayer→paraffin-type-bilayer and the packing density of HDTMA+ in the interlayer in-creases gradually. In the intermediate stages, different mod-els may coexist.

唐寅与明中叶学术思潮

复古思潮盛行的明中叶,唐寅的文艺观与前七子的复古主张、王阳明的心学、唐宋派的本色论,既有精神上的相通,又显示出价值取向上的不同。他们在哲学思想、诗文理论、诗文创作实践之间,既有联系,又有区别。唐寅等吴中文人与前七子在复古态度上是一致的。但前七子复古主旨是要恢复具有儒家传统的古典主义诗歌风貌,而唐寅等吴中文人复古是要实现自我情感和才性的自由抒发,他和王阳明在肯定人的主体地位,突出人的主观能动性方面有一定的契合。但唐寅在肯定情欲、重视人的自然要求、追求个性等方面远远超过了他的同龄人;他提倡文学创作抒发真情实感,不事雕琢,一任自然,这种主张与唐宋派要求文章文从字顺、本色自然、反映真情的观点也有相合之处。唐寅的文学创作在一定程度上影响和推动了明代学术思潮的转变,其独特的地位和影响是不可忽视的。

元代经济伦理思想的历史特质与价值

元代是一个特殊的历史时期,游牧统治者“起于内不足”的商业精神、务实作风和传统儒士社会地位的下沉,使元代的社会基础和经济伦理关系发生了巨大变化。传统儒学、蒙古文化和西域文化作为农耕文化、游牧文化和商业文化的代表碰撞交融,形成了这一时期的多元文化面相,并间接作用于元代的经济伦理思想,使其表现出明显的“致用”倾向和“务实”特征。围绕经济伦理的核心——“义”与“利”、“本”与“末”等关系问题,元代的思想亦发生转变。“利”和“欲”的合理性在现实中得以证明,并被赋予了“义”或“理”的意义;“末”业进一步冲破传统重“本”思想的压制,被统治者大力推崇,并被理学家视作“亦有可为”。经世致用的义利观和农商并重的本末观,成就了这一时期独具特色的经济伦理思想,并充分展现其历史特质与价值。

随着中国文学海外传播的不断推进,当代民族文学的英译成果逐渐增多,呈现出丰富多元的传播态势。权威译者与出版媒介共同促进了民族文学海外象征资本的生成、转化与累积。从接受情况来看,当代民族文学仍徘徊在海外大众读者的视线之外,但民族书写中呈现的地域特色、国族想象以及关于“自我”与“族裔”的身份诉求却引起了西方学者的研究兴趣。在“东方主义”的凝视中,中国民族书写的丰富性不可避免地被西方话语遮蔽和异化。当代民族文学如何突破跨文化交流的困境,是中国文学海外传播亟待解决的议题。

Background and Objective: Early diagnosis of nasopharyngeal carcinoma (NPC) is difficult due to the insufficient specificity of the conventional examination method. This study was to investigate potential and consistent biomarkers for NPC, particularly for early detection of NPC. Methods: A proteomic pattern was identified in a training set (134 NPC patients and 73 control individuals) using the surface-enhanced laser desorption and ionization-mass spectrometry (SELDI-MS), and used to screen the test set (44 NPC patients and 25 control individuals) to determine the screening accuracy. To confirm the accuracy, it was used to test another group of 52 NPC patients and 32 healthy individuals at 6 months later. Results: Eight proteomic biomarkers with top-scored peak mass/charge ratios (m/z) of 8605 Da, 5320 Da, 5355 Da, 5380 Da, 5336 Da, 2791 Da, 7154 Da, and 9366 Da were selected as the potential biomarkers of NPC with a sensitivity of 90.9% (40/44) and a specificity of 92.0% (23/25). The performance was better than the current diagnostic method by using the Epstein-Barr virus (EBV) capsid antigen IgA antibodies (VCA/IgA). Similar sensitivity (88.5%) and specificity (90.6%) were achieved in another group of 84 samples. Conclusion: SELDI-MS profiling might be a potential tool to identify patients with NPC, particularly at early clinical stages.

建立了一个新的非线性气动弹性模型,对低速流场中柔性悬臂板的后颤振响应特性进行了分析。建模中考虑了结构几何非线性、气动力非线性以及两者之间的强耦合效应。通过实验数据对所建立的气动弹性模型进行了验证。发现在低速流场中柔性悬臂板可能会以周期加倍的方式进入混沌运动。结构几何非线性效应和翼尖涡引起的非定常气动力效应对柔性悬臂板的结构响应有显著影响,而尾涡变形引起的非定常气动力对结构运动的影响较小。还研究了不同耦合算法的差异,给出了小展弦比大柔性结构非线性气动弹性数值仿真时耦合策略的选择依据。
