虚幻影像的现代轨道：中国广告的政治经济学解读

广告在电视经济结构中起着举足轻重的作用,虚幻影像的本质正使其成为现代生活的新宗教。中国政治广告也以独特的形式,影响着政治生活。社会主义架构要求国家必须对电视广告予以干预,使广告不能偏离中国现代性轨道。     

Bi掺杂的PLZT陶瓷水热制备与性能研究

通过水热合成法制备了Pb0.91（La1-zBiz）0.09（Zr0.65Ti0.35）0.9775O3陶瓷。采用XRD和阻抗分析仪分别对陶瓷进行物相分析和介电性能的研究。结果表明,制备得到的PLZT是纯四方相晶体。随Bi掺杂浓度增大,相变温度升高,介电常数变化,存在弥散相变。     

拓展农民培训资金来源的政策建议

拓展资金来源是解决农民培训资金短缺问题的必然选择。其主要方式是：建立农民培训的激励机制,发挥农民作为培训主体的积极性;加强政府宏观调控,完善中央财政转移支付制度,发挥政府投资的主导作用;出台优惠政策,通过完善财政、税收和金融等政策,提高企业、非营利组织以及金融组织投资农民培训的积极性;完善法律法规,为农民培训创造良好的法制环境。     

CFD simulation with enhancement factor of sulfur dioxide absorption in the spray scrubber

A model describing the absorption process of SO2 into limestone slurry with a spray scrubber is presented. Both the physical performance of the spray liquid in the scrubber and the involved chemical reactions are analyzed in the model. A continuous concentration change ofH＋ was solved by iterative coupling using Matlab, and it was found that there was a remarkable influence on the concentration of the other elements in the process of SO2 absorption. The calculations show that the enhancement factor exponentially grows with an increasing value ofpH and logarithmically decays with an increasing value of the driving force. To verify the accuracy of the model, experiments were also carried out, and the results suggest that the model, after combining the physical performance of the spray and the enhancement factor, can more precisely describe SO2 absorption in a spray scrubber. Furthermore, a commercial computational fluid dynamics （CFD） tool is used to perform several simulations which describe and clarify the effects of variables on SO2 absorption. The results of numerical simulation can provide a basis for further design and optimization of the scrubber.     

求仕与李白诗风的嬗变

李白有着追求精神自由、反抗传统束缚的叛逆者性格。他的求仕实质是以政治功利的实现来张扬自我。李白进入宫廷,作为司马相如式的"天颜有喜近臣知"的文学侍从待侍帝侧,其拙于政治才能、疏于人际关系等自身弱点暴露无遗,主体精神带来了官场最为忌讳的浮躁,特别是独立人格和依附人格的冲突,使李白不愿苟合取容,表现出对求仕的放弃。从"仰天大笑出门去,我辈岂是蓬蒿人"到"宁可草中耿介死,不求黄金笼下生",李白经历了极其复杂、痛苦的人生转折。其诗作是其现实忧怨、寂寞心态和复杂难言的人生感慨的外化。这是一个敏感的诗人对生命和现实的怀疑和悲哀,他复杂难言的人生感慨,多以饮酒、游仙、闺怨、思妇等形式表现出来。前人指责"李白诗,乃妇人与酒耳",实乃不实之论。

职业教育吸引力不足的原因探析

发展职业教育是当前社会经济发展的急需,但由于长期形成的社会观念、投入不足和保障机制缺失以及与普通教育沟通不畅、管理体制不顺等原因,职业教育吸引力严重不足。本文从社会观念、投入不足、保障机制缺失、与普通教育沟通不畅、管理体制不顺等方面进行了探析。     

Early reperfusion strategy for acute myocardial infarction: a need for clinical implementation

Reperfusion is the key strategy in acute ST-segment elevation myocardial infarction (STEMI) care, and it is time-dependent. Shortening the time from symptom to reperfusion and choosing the optimal reperfusion strategy for STEMI patients are great challenges in practice. We need to improve upon the problems of low reperfusion rate, non-standardized treatment, and economic burden in STEMI care. This article briefly reviews the current status of reperfusion strategy in STEMI care, and also introduces what we will do to bridge the gap between the guidelines and implementation in the clinical setting through the upcoming China STEMI early reperfusion program.
