网络给思想政治教育工作带来的挑战与对策

当前，日益迅猛的网络对青少年学生的行为模式、价值取向、政治态度、心理发展、道德观念等已经产生越来越大的影响。如何在网络时代加强青少年的思想政治教育就成为一个亟待解决的重大课题。     

试论《碧鸡漫志》的批评方法

《碧鸡漫志》作为宋代第一部系统的词学著作,在探讨词的起源时独树一帜,意义深远。在文学批评方法上,继承借鉴古人知人论世和分派列品的做法。这种批评方法为继承者所效仿,给后人开拓了道路。     

"预设"不可弱化--兼谈对课程改革的一点思考

近来读了一些文章,也参加过不少教研活动,有一个问题一直在头脑里打转:预设就那么不重要了?“生成”难道就不可以预设?如果大家都来探究预设生成,让我们对教学过程了如指掌,对教学结果成竹在胸,岂不是更好吗?为探讨上述问题,先向大家提供一个笔者的教学案例:     

成人教育管理体制改革论

科学的管理体制是实施科学管理的前提和保证。建国以来，我国成人教育管理体制经历了长达40余年的“一级统管”阶段。从20世纪90年代起，开始了“两级管理，分类负责”的改革。然而截至目前，我国成人教育滞后于时代发展的要求。21世纪前期，我国应进一步深化成人教育管理体制改革。     

湖州非物质文化遗产与乡村旅游融合发展研究

非物质文化遗产需要传承和弘扬,地方旅游业发展需要文化支撑,如何将二者融合发展,值得研究。本文收集、整理湖州非物质文化遗产资料,对其数量、类型、分布等进行分析,并实地调查了湖州旅游发展过程中对非物质文化遗产的利用现状,提出湖州乡村旅游应充分利用非物质文化遗产,可从打造舞台盛宴、创新导游解说、打造非遗属性旅游纪念品三个方面提升乡村旅游的文化内涵。这样,既可以更好地保护地方非物质文化遗产,又可以推动地方旅游文化事业,二者的结合是双赢之举。

Removal of Toluene by Adsorption/Desorption Using Ultra-stable Y Zeolite

The adsorption performance of toluene on ultra-stable Y zeolite(USY) was studied via dynamic adsorption. The effects of bed temperature, initial concentration, and feed flow rate on adsorption were investigated. The Yoon–Nelson model was used to fit the toluene breakthrough curves. The length of mass transfer zone was calculated based on breakthrough curves. The Langmuir–Freundlich model fit the adsorption isotherms of toluene on USY, which indicated that the surface of USY was heterogeneous. The adsorption isosteric heat calculated from adsorption isotherms ranged from 54.3 to 69.8 kJ/mol, indicating physical adsorption. The combined technique of temperature swing adsorption with vacuum swing adsorption(TVSA) exhibited excellent desorption performance, which was attributed to the low desorption activation energy. Under optimized TVSA conditions, the desorption rate of toluene reached 90.6% within 10 min. The long-term cyclic utilization results indicated that the adsorption capacity of USY was stable.     

Enhancing cellular immune response to HBV M DNA vaccine in mice by codelivery of interleukin-18 recombinant

Objective: To investigate the effect of interleukin-18 (IL-18) on immune response induced by plasmid encoding hepatitis B virus middle protein antigen and to explore new strategies for prophylactic and therapeutic HBV DNA vaccines. Methods: BALB/c mice were immunized with pCMV-M alone or co-immunized with pcDNA3-18 and pCMV-M and then their sera were collected for analysing anti-HBsAg antibody by ELISA; splenocytes were isolated for detecting specific CTL response and cytokine assay in vitro. Results: The anti-HBs antibody level of mice co-immunized with pcDNA3-18 and pCMV-M was slightly higher than that of mice immunized with pCMV-M alone, but there was not significantly different (P>0.05). Compared with mice injected with pCMV-M, the specific CTL cytotoxity activity of mice immunized with pcDNA3-18 and pCMV-M was significantly enhanced (P<0.05) and the level of IFN-γ in supernatant of splenocytes cultured with HBsAg in vitro was significantly elevated (P<0.05) while the level of IL-4 had no significant difference (P>0.05). Conclusion: The plasmid encoding IL-18 together with HBV M gene DNA vaccines may enhance specific TH1 cells and CTL cellular immune response induced in mice, so that IL-18 is a promising immune adjuvant.     

弹塑性断裂的内参量热力学分析——Ⅰ.线弹性裂纹体的裂纹扩展

本文在内参量热力学的理论框架内详细讨论了线弹性裂纹体的裂纹扩展问题。对线弹性断裂力学中所涉及到的各种能量关系作了统一的整理,其中包括Irwin的弹性能释放率——裂纹扩展力,Griffith的脆性断裂准则,以及Irwin-Kies的柔度公式和Paris的位移公式。本文以中心裂纹体为例,详细计算了裂纹扩展的稳定性,并区分恒载荷和恒位移两种情况,对材料断裂韧性测试中所遇到的失稳扩展,稳定扩展以及进发现象提供了理论说明。
