The alternative of prohibition and relaxation: tentative study on evolution of shochu Policy in Qing
酿酒业作为一个已有数千年历史的农产品加工行业,在清代社会经济生活中占据着重要的地位。由于其与粮食生产的特殊关联性,因此国家在制定及执行烧酒政策禁与弛的过程中不得不认真抉择。本文通过分析清代烧酒政策的演变历程,总结其变化的趋势,并通过阐述其与当时社会经济因素的互动,以及中央和地方权力等政治力量对该政策禁弛的决策作用,探讨烧酒政策的禁弛对当时社会政治经济的影响。全文基本结构与内容如下: 绪论阐述选题缘由,进行学术史回顾,提出研究的资料来源、基本思路以与概念界定。 第一章介绍清代烧酒政策演变概况,分前中后三个阶段分别阐述烧酒政策演变的历程,总结其变化的大致规律。 第二章通过论述烧酒政策与社会经...The brewing industry ,as one of agroprocessing industries with the history of nearly several thousand years, occupied an important position in the economic life of Qing dynasty . The shochu policy, prohibition and relaxation, called for serious deliberation because of its special relationship with grain- production. This thesis will analyze the evolution of shochu policy in Qing dynasty to summari...学位:历史学硕士院系专业:人文学院历史学系_专门史学号:1032007115157
傣族祭寨神仪式空间的排他性
傣族祭寨神仪式期间,傣族人物理的现实时空进入宗教的神圣时空,使村寨形成一个封闭的神圣空间。相对于村寨空间,寨神居住的寨神林空间在宗教体验上则更具神圣性。祭寨神仪式空间把佛和寨外排除在外,寨神林把寨内的女性排除在外。村寨内外、寨神林内外的空间安排,反映了傣族祭寨神仪式空间的排他性,这种排他性充分体现了集体表象的功能
论我国浮动抵押制度的引入与完善
新近通过的《物权法》首次确定了浮动抵押制度,对于这一立法举措,学界褒贬不一。文章首先从浮动抵押制度的起源、国外制度和特点入手,揭示其本质,然后从四个方面论证了我国引入浮动抵押制度的合理性,随后对《物权法》相关规定进行探讨,最后对完善我国浮动抵押制度的难点——信用问题和接管人制度提出建议
Incorporation of Confucianism Into Taoism From Han Dynasty To Southern and Northern Dynasty
在传统的三教关系中,佛教是从印度发源的外来宗教,终究还是儒道两家更能深刻地阐释中国特有的传统文化。基于儒家与道教在各层面的紧密联系,本文尝试析论道教从儒家学说中吸收了哪些思想,并以汉魏六朝为例,因“援儒入道”是从汉魏晋南北朝开始发展,以后的朝代只是加强而已。 本文内容将环绕着儒家与道教的各方面对比来进行研究,首先是分析与评论在三教关系视野下的儒道关系。这是从较大的视角来看儒道关系,“道”包含了哲学的道家与宗教的道教。接着将视线集中在论文主题,即“援儒入道”,分析道教融摄儒家学说的内因与外缘及魏晋南北朝道教吸取儒学的途径。通过阐述道教与儒家的密切关系来说明中国文化是以儒道思想建构而成的这一事实...In the process of founding, Taosim has absorbed many folks cultures and beliefs, vary from traditional god worshipping, Tao thinking of Pre-Qin Dynasty, theology to Tao of HuangLao. Besides, it had also absorbed Confucianism, Buddhism, Moism, YinYang and other traditional thoughts. In the traditional “three religions” relationship, Buddhism is a religion originated from country out of China, there...学位:哲学博士院系专业:人文学院_中国哲学学号:1042011015417
PIV study on spray field of coal-water slurry air-blast electrostatic atomization
为探索高压静电场中水煤浆荷电颗粒相的动力学特性,基于新型三级y型水煤浆气力式雾化喷嘴-环电极的静电雾化实验系统,利用粒子图像速度仪(PIV)对雾炬内水煤浆荷电雾滴的运动规律进行了深入的实验研究。研究结果表明:在射流边缘区域内的水煤浆荷电细小雾滴群在静电场力的作用下,沿程将偏离常规雾化的运动轨迹,靠近电极处的流线发生明显的弯曲变形并随电压的不断增强呈现出3种典型形式;荷电雾滴的轴向速度随电场力增强而减小,并在射流核心区内的沿程截面上分布趋于均匀,径向速度随电场力的增强而增加,并在射流核心区内的沿程截面上呈线性分布;流场中雷诺应力及涡量均集中分布在射流轴线两侧,随电场增强,雷诺应力峰值显著增加并在横截面上逐渐外移,随射流远离喷嘴,其截面雷诺应力分布趋于平缓。In order to explore dynamic characteristics of coal water slurry charged particle in the high voltage electrostatic field,using particle image velocimeter( PIV),an electrostatic atomization experiment system consisting of a novel three-level Y-type spraying-pneumatic atomizing nozzles and a ring electrode was applied to perform an in-depth study on the dynamic characteristics of charged coal-water slurry( CWS) droplets in a high voltage electrostatic field.Experimental results indicate that: the trajectory of fine coal-water slurry droplets clusters at the edge area of the spray field deviated from conventional atomization under the action of static electric force.The streamlines near the electrode obviously bend and deform,which would present three typical forms with the increasing voltage.The axial velocity of charged droplets of coal-water slurry would decrease and distribute more evenly while the radial velocity would increase and distribute linearly along the spraying developing sections of radial direction with the increasing electrostatic force.Reynolds stress and vortices in the flow field would be concentrated in the spray axis on both sides,the peak value of Reynolds stress would increase significantly and gradually move out on the cross with the electric field enhanced.Reynolds stress would distribute more smoothly as the spray developing away from the nozzle.福建省科技计划重点资助项目(2012H0031); 福建省科技厅高校专项资助项目(JK2011028

袋鼠皮蛋白肽对H2O2诱导人肝细胞LO2氧化损伤的影响
为探索袋鼠皮蛋白肽如何修复受H2O2损伤的LO2细胞,通过建立H2O2诱导人肝细胞LO2氧化损伤的模型,研究袋鼠皮蛋白肽对氧化应激损伤的人肝细胞LO2的修复作用。结果表明:袋鼠皮蛋白肽在0~0.5μg/μL浓度范围内不仅对LO2细胞活性没有抑制作用而且显著提高了受损细胞的存活率,改善了细胞的形态;与此同时,显著降低了H2O2诱导的丙二醛释放,降低了蛋白质羰基含量和活性氧的水平,使细胞受氧化损伤的影响减小。厦门大学横向课题(XDHT2017407A);;福建省博胜生物科技有限公司项
