The Artistic Communication of Taiwan Comics ——From the Perspective of Industry Development
漫画是台湾现代文化艺术的一个有机组成部分,台湾漫画产业是漫画艺术实现广泛社会传播与价值增长的商业化途径与经济活动集合。市场经济环境下,漫画的传播遵循艺术规则,也有赖于产业经营的策略。艺术对社会的影响来自于其审美性,也建立于文化消费的实际行动之上。本论文从台湾漫画的历史出发,从艺术层面与产业层面对其发展状况进行了梳理,分析了艺术创作上台湾漫画的特征与个性,表明了中国文化传统对其题材与风格的重要影响,也指出了外来文化尤其是日本文化在台湾漫画领域的渗透性影响。台湾漫画产业明显发迹于代工经济,这是与台湾经济发展的脉络相一致的,这为台湾漫画产业赢得了一定的世界声誉,却也遗留下了负面的深远影响。论文探讨了...Comic is an integral part of Taiwan’s modern arts and cultures, and comics industry is the commercial way and collection of economic activities for comic arts to achieve widespread social communication and value growth. In the market economy environment, communication of comics follows the rules of arts, and depends on the strategy of industrial management. The social influence of arts derives fro...学位:文学博士院系专业:新闻传播学院_传播学学号:3192009015367
Study on Asymmertic Synthesis of Chiral Hydrocarbazoles Catalyzed by Octahedral Chiral-at-Metal Complexes
四氢咔唑是许多天然产物的重要骨架,也可充当合成药物的重要中间体,特别是多取代手性四氢咔唑环较为常见。当前,合成这类手性结构的方法较为有限,其中最主要的方式是通过2-烯基吲哚或者3-烯基吲哚的不对称Diels-Alder反应得到。然而,3-烯基吲哚Diels-Alder反应来构建光学活性的四氢咔唑环的工作仅有少量报道。因此,发展新的方法来合成手性四氢咔唑仍然具有重要的意义。 在本论文中,我们将首先以课题组发展的新型手性铑Lewis酸催化剂用于N-Boc保护3-烯基吲哚与α,β-不饱和酰基咪唑间的不对称Diels-Alder反应,构建三个连续手性中心的四氢咔唑环。该催化剂的结构特点是,其中心金属...Hydrocarbazoles are common structural motif in many nature products and drug intermediates and often possess multiple stereocenters within the highly substituted hydrocarbazole core. Versatile methods for the efficient construction of highly functionalized chiral hydrocarbazoles are therefore sought after and often make use of Diels-Alder reactions with 2- or 3-vinylindoles as the key reaction to ...学位:理学硕士院系专业:化学化工学院_有机化学学号:2052012115159
Design and Implementation of Online Question Answering System for Wuzhou University
科学技术的进步,密切了人与人之间的联系,利用网络进行信息沟通,大大提高了生活的便利性。在教育领域,现在利用网络,开展网上学习,足不出户就能够增长知识,提高学习效率。近年以来,梧州学院的教学工作取得了很大的发展,招收学生的人数得到增多,在校生以及网络教育的人数持续增长,这给学校的教学工作带来了挑战。随着学生人数日益增长,教师与上课地点并不固定,学生与老师之间只能开展有效的交流,在时间与空间方面都受到限制,师生间信息交流不顺畅,有关的教学工作难开展,为此需要开发设计一个在线答疑系统,这对于学校教学水平的提高必将大有帮助。 本系统采用B/S基本结构,使用SERVLET、JSP、JAVASCRIPT...With the development of science and technology, the relationship among people is established closely and a more convenient life is brought by communication on line.

Photosynthetic capacity of three common species of macroalgae and the application in coral aquarium
利用水下饱和脉冲调制叶绿素荧光仪(dIVIng-PAM)测定了珊瑚养殖水处理中3种常见大型海藻石莼(ulVA lACTuCA)、条浒苔(EnTErOMOrPHA ClATHrATA)和羽状蕨藻(CAulErPA MEXICAnA)光能转化效率(fV/fM),快速光曲线(rlC)相关参数和非光化学淬灭(nPQ)。结果表明:石莼和条浒苔的fV/fM分别为0.808±0.004和0.816±0.009,显著高于羽状蕨藻。最大相对电子传递速率rETrMAX(17.52±2.92和19.59±4.43μMOl E·M-2·S-1)、半饱和光强Ik(53.41±8.18和59.71±13.52μMOl PHOTOnS·M-2·S-1)也明显高于羽状蕨藻(rETrMAX和Ik分别为13.72±5.41μMOl E·M-2·S-1和32.67±14.06μMOl PHOTOnS·M-2·S-1),表明石莼和条浒苔有着比羽状蕨藻更高的光合能力和对强光的耐受能力,光保护能力更强;羽状蕨藻较高的rlC初始斜率α表明其在弱光下拥有更强的光捕获能力,弱光下光合效率更高;随光照的增强(0~373μMOl PHOTOnS·M-2·S-1),羽状蕨藻nPQ的增幅有限(0~0.2),最大值仅为条浒苔和石莼的38.1%和62.5%,表明这种藻类更容易受到强光的抑制。因此,在珊瑚养殖的水处理中,可以根据不同的光照选择适宜的藻种或藻种组合并根据光梯度进行布局,反之也可以根据藻种来选择合适的光源,以达到最佳的处理效率。This study investigated the difference of photosynthetic capacity in three macroalgae species( Ulva lactuca,Enteromorpha clathrata,and Caulerpa mexicana) commonly used for nutrient removal in coral aquariums.The photochemical efficiency( Fv/Fm),parameters relevant to rapid light curve( RLC) and non-photochemical quenching( NPQ) in the macroalgae were measured by underwater saturation pulse modulated chlorophyll fluorometer( Diving-PAM).The results showed that Fv/Fmwas 0.808 ± 0.004 for U.lactuca and 0.816 ± 0.009 for E.clathrata,which were higher than that for C.mexicana.Higher maximum relative electron transfer rates( rETRmax)( 17.52 ±2.92 and 19.59 ±4.43 μmol e·m- 2·s- 1) and half-starved value of light intensities( Ik)( 53.41 ±8.18 and 59.71 ±13.52 μmol photons·m- 2·s- 1) were observed in U.lactuca and E.clathrata than that in C.mexicana( 13.72 ± 5.41 μmol e·m- 2·s- 1for rETRmaxand 32.67 ± 14.06 μmol photons·m- 2·s- 1for Ik),indicating that U.lactuca and E.clathrata have stronger photosynthetic capacities,photo-protection capacities and tolerance to higher intense light than C.mexicana.A significantly lower RLC initial slope α in C.mexicana implied that this algal species has a higher photosynthetic capacity under weak light condition.With increasing the light intensity( 0- 373 μmol photons·m- 2·s- 1),however,C.mexicana had a limited increase of NPQ( 0- 0.2),the maximum of which was equivalent to 38.1% of that in U.lactuca and 62.5% of that in E.clathrata.These results indicate that the photosynthesis of E.clathrata may be more easily limited by intense light.Our study suggests that the selection of algal species for nutrient removal in a coral aquarium should be adapted to the light intensity.Single species or the combination of different species of macroalgae can be selected according to the illumination of the coral aquarium in order to maximize the efficiency of nutrient removal.国家海洋局第三海洋研究所基本科研业务项目(海三科2011033); 厦门海洋研究开发院共建项目; 海洋公益性行业科研项目(201105012)资
Study and Application of Data Mining in the Analysis and Forecasting of Railway Passenger Flow
随着全国高铁的大规模建设和投入使用,乘坐火车变得更加方便快捷。但在春运、“黄金周”、节假日形成的客流高峰,的确给铁路部门的运输带来了巨大的压力。如果能通过对车站客流数据的分析,对客流高峰期的客流量和客流走势进行预测,就能很好地为管理者和技术人员制定运输方案,组织优化客流提供决策支持。而目前客流的分析预测的研究不是很充分,所做的工作仍处于初步数据统计阶段,预测方式基本上是人工化操作,耗费大量的时间和人力,物力。 本文主要对数据仓库和数据挖掘技术进行研究,应用这些技术对铁路客票发售和预订系统中的海量数据进行处理,将有效的数据挖掘技术应用于铁路客流分析,建立合理的预测分析模型,为客运部门合理安排...With the national building and application of high-speed railway, it is more convenient to travel by train.
