密集颗粒物料流动特性数值模拟研究

工业过程中常涉及到密集颗粒物料的处理，深入认识密集颗粒物料的流动特性对设计、优化和放大相关设备至关重要。本文以移动床和喷动床为研究对象，考察系统中颗粒物料的流动特性，探索现有密集颗粒物料相关本构模型的预测精度和适用性。本论文第二章采用离散单元法模拟研究了移动床中颗粒物料的卸料特性，为第三章连续性模拟结果的合理性提供验证数据。离散模拟结果表明，随着初始堆积高度的增大，颗粒物料的流型逐渐由C类漏斗流过渡到B类半整体流。漏斗流结构下，流动区特征宽度随卸料的进行呈现（增大）&mdash;恒定&mdash;减小的变化趋势。半整体流结构下，当床层高度降到某一临界值时，流型突变为漏斗流，之后流动区特征宽度呈单调递减的变化趋势。这一结果说明，移动床卸料过程中，流动区宽度与卸料历史密切相关。第三章基于连续介质模拟，考察了目前文献中代表性的颗粒粘度模型（Schaeffer、S-S和&mu;（I）模型）对模拟结果的影响。模拟结果表明，对于卸料初期为漏斗流的系统，Schaeffer模型和&mu;（I） 模型都能预测出漏斗流流动结构，但所预测的流动区特征宽度的数值与变化趋势明显偏离离散单元法模拟结果；对于卸料初期为半整体流流型的系统，Schaeffer模型和&mu;（I）模型能够预测出移动床内物料从B类半整体流向C类漏斗流的转化过程，且流动区特征宽度变化趋势与离散单元法模拟结果定量一致。对于所考察的初始堆积高度，S-S模型的预测结果始终为半整体流，明显偏离了离散单元法数值模拟的结果。 第四章基于气固喷动床，进一步检验了以上三种粘度模型对模拟结果的影响。模拟结果表明，&mu;（I）模型预测得到的喷泉区高度、平局空隙率以及喷动区轮廓更接近于实验结果；Schaeffer模型得到的床层压降最接近实验测量值。三种粘度模型在喷泉区与喷动区内的预测结果差异不大，但在环隙密相区内&mu;（I）模型的模拟结果明显优于其他模型。综合考虑，相较于Schaeffer与S-S模型，&mu;（I）模型在喷动床预测中显示出更大的优越性。&nbsp;</p

Aspects of adhesion between CAD/CAM ceramics and resin cements

Glass ceramics are one of the preferred choices in the case for preservation of tooth structure. They also exhibit excellent aesthetic outcomes, and life-like translucency. Moreover, glass ceramics can provide better adhesion to the underlying tooth preparation, compared with metal-bonded ceramics and oxide ceramics. This is achieved by application of HF etching and silanization, followed by bonding with resin cement. The resin cement is applied as the means to provide a seal, adhesion and ‘filler’ in the small space that exists between a restoration and prepared tooth. These unique properties have given rise to expanded restoration designs for glass ceramics in comparison to other ceramics, e.g., veneers, inlays or onlays. Hence, durable and stable adhesion is strongly required for the long-term success of these restorations. The aim of this project was to evaluate the durability of adhesion between CAD/CAM ceramics and resin cements as well as the effect of different factors on long-term ceramic adhesion. In the first experiment, two bonding models were compared and contrasted using a microtensile bond strength test. Two surface treatments and two resin cements were also examined. Ceramic to ceramic, as a bonding model, was found to be better than a ceramic to resin composite model. Surface treatments and resin cements had a significant effect on the microtensile bond strength. The second experiment aimed to evaluate the stability of long-term adhesion using six resin luting cements when bonded to three different CAD/CAM ceramics in water over 12 months. According to the outcomes of this study, VITA Suprinity® and VITA Enamic® demonstrated better long-term adhesion compared to IPS e.max® CAD. Furthermore, the microtensile bond strengths of ceramic and resin cement decreased up to 3 months but thereafter became relatively stable. Different resin cements showed different bonding behaviour during prolonged storage time. The third study examined the effect of two etching times on long-term ceramic adhesion and the effect of six resin luting cements on durability of adhesion. This study indicated that prolonged etching time could increase the microtensile bond strength of glass ceramics in the short-term, however, different etching times did not have an obvious influence on the long-term adhesion. In the fourth experiment, an evaluation of sorption, solubility and dimensional change of six resin luting cements immersed in various storage media was undertaken. Significant differences were observed in the sorption, solubility and dimensional change of the cements when exposed to the different storage media over time. The objective of the last experiment was to evaluate the effect of immersion time and media on fracture toughness of six resin cements. It was concluded that fracture toughness varied among the cements and the value decreased over time. Furthermore, the three storage media evaluated in this study seemed to not have had a significant effect on the fracture toughness. It was concluded that, in general, lower sorption, solubility and dimensional change in resin cements seems to produce a higher fracture toughness and microtensile bond strength to glass ceramics.published_or_final_versionDentistryDoctoralDoctor of Philosoph

新两线旧局限 ：马国民主行动党与马来政党关系变迁 = Rising two-coalition system with past constraints: the history of relationships between Democratic Action Party (DAP) and Malay political parties in Malaysia

2008年的“308海啸”以后，政治反对势力的结盟在国内普遍受到重视，也被认为将是接下来的选举趋势与常态。本文以民主行动党为对象，自80年代末开展的两线政治风潮至2016年的后安华时代，探讨族群政治背景下，民行党与其它马来政党对垒、合作或竞争的互动关系。在不利的外部政治环境下，民行党多次联合其它马来反对势力对垒国阵。反对势力的结盟仍旧以族群/宗教为基础，面对内部分歧，民行党需要暂时达成协商与合作，也要顾及原则底线的坚持。在族群、宗教课题上的无法妥协让合作关系异常脆弱，有时也成为国阵击倒对手的筹码。另外，2013年全国大选后，如何突破华族政党形象获取多种族的支持，成为民主行动党发展的侧重点，但数次补选的失利均显示“马来化路线”效果不彰。如今的后安华时代，国阵与对手仍然热衷在族群与宗教课题上竞争，民行党作为华人政治反对力量更向马来人靠拢，让马国的政治力量呈现一种倒退的状态。A two-coalition system is now a reality for Malaysia's political landscape. Ever since the '308 political tsunami', which United Malays National Organization(UMNO) lost five of its state legislatures and its supermajority in parliament to opposition party during the Malaysia's 12th general elections in 2008, public aspiration and expectations for the opposition political coalition, Pakatan Rakyat(PR), were a record high. This study attempts to investigate the relationship between Democratic Action Party(DAP) and Malay political parties from the late 80s till Post-Anwar era in 2016 where ethnicity and religion still hold crucial roles in determining Malaysia's general election outcomes. Since 1990, DAP has formed Malaysian opposition coalitions with other Malay political parties several times. The attempted coalitions, however, are dismissed eventually. DAP and other Malay parties, often the Pan-Malaysian Islamic Party (PAS), were unwilling to set aside their differences, which attributed greatly to the dismissal of coalitions. With evidence of strong support from non-Malay voters in the 13th general election, DAP started to adjust its campaign strategies to garner more support from Malay communities in the semi-urban and rural constituencies. In the post-Anwar period, both coalitions, especially UMNO and PAS, employ ethnicity and religious topics in their campaigns to comply to their political agendas. As DAP, a non-Malay opposition party started to be more Malay-centric, Malaysia's political landscape might be taking a turn for the worse.Bachelor of Art
