Conversation Analysis of the American Sitcom Friends

本论文从会话分析角度﹑系统角度以及语用学角度对美国情景剧《朋友》中的会话进行分析研究。情景剧中的会话，由于其特殊性（可以把它看成是书面形式的会话），很少有人进行研究。因此我们选择了情景剧中会话作为分析的对象，研究其话轮，语序及话语转换，旨在于探讨会话分析的理论是否适用于情景剧中的会话，探讨话轮和话轮转换在情景剧中起的作用以及自然状态下发生的语言和情景剧中的话语之间的差异。我们着重研究《朋友》中的会话参与者是选择怎样的方式开始﹑发展并结束一段会话的，并研究他们使用哪些具体的字，词，句，以及怎样的说话方式使得会话具有情景剧的特点。语言是具有意义潜势的选择系统。第一个说话人选择的话语可以为第二个说话...Sitcom conversation, due to its speciality (it can be seen as the written talk), is rarely studied. The present thesis attempts to explore conversation in the American television sitcom Friends from the ethnomethodological perspective, the systemic perspective and the pragmatic perspective. Sitcom conversations are taken as the subject to examine the areas of turns, sequences and exchanges with th...学位：文学硕士院系专业：外文学院外文系_英语语言文学学号：20030404

Typical Chlorination and Oxidation Studies of non-IPR Fullerenes Containing Fused Pentagons (C64、C56)

富勒烯家族有着数量庞大的碳笼异构体，其中最常见的是符合独立五元环 （IPR）规则的Ih-#1，812C60和D5h-#8，149C70。根据IPR规则，富勒烯碳笼上的所有五 元环均被六元环分隔开的结构（IPR富勒烯）才是稳定的，而那些含有相邻五元 环的碳笼（非IPR富勒烯）则是活泼的、不稳定的。实际上，对于碳数小于70的 碳笼，除了Ih-C60，其他的碳笼均不可避免的含有相邻五元环。对某一碳数的富 勒烯，非IPR富勒烯异构体的数量远远大于IPR富勒烯。目前，得到表征的非IPR富 勒烯已有数十种，然而关于非IPR富勒烯的稳定性和反应性的理论研究，还需要 更多的实验结果来佐证和补充。...There are a huge number of isomers in fullerene family. The most common fullerenes are Ih-#1,812C60 and D5h-#8,149C70 which obey the isolated pentagon rule (IPR).According to the isolated pentagon rule, which states that the fullerenes with isolated pentagon rings separated by hexagon rings are stable. These kind of stable fullerenes with isolated pentagon rings are called IPR fullerenes. Otherwi...学位：理学博士院系专业：化学化工学院_无机化学学号：2052010015365

The Research on Linkage between Talents Training in Higher Vocational Colleges and Demands on Human Resources Market ------ A case Study on Xiamen Institute of Software Technology

目前，我国高等职业院校人才培养与市场需求并非完全匹配，主要表现在:一方面，毕业生就业难，一毕业就失业的现象越来越明显；另一方面，企业招工难的“用工荒”现象日益突出。因此，对高等职业院校人才培养与市场需求相对接的问题进行深入研究具有十分重要的现实意义。 本文依据人力资本理论之人力需求预测法，对目标年份各部门所需的人才进行预测，为高等职业院校人才培养提供依据，使高等职业院校培养出来的人才能够适应市场的需求，实现人才培养与市场需求相对接。本文依据的另一理论---建构主义理论，提出一切知识是个体在认知过程的基础上，在跟经验世界对话中主动建构起来，强调实践教学在高等职业院校人才培养与市场需求相对接中的...Recently, there is a serious problem on talents training in Higher Vocational Colleges without really meeting the demands of Human Resources Market. As the consequence of this broken linkage, some graduates couldn’t find jobs after graduation. There are two phenomena in Human Resources Market: It is so difficult for graduates to find corresponding jobs, and it is quite hard for enterprises to get ...学位：文学硕士院系专业：教育研究院_高等教育学学号：X200728000

To date, only C60Cl6 can be macroscopically synthesized. Here we report a facile synthesis of Ih-C60Cl8 and Ih-C60Cl10, as well as their separation and analyses

一例补体抑制剂治疗欠佳的再生障碍性贫血-阵发性睡眠性血红蛋白尿患者的多学科诊疗分析

一例青年男性患者诊断再生障碍性贫血伴阵发性睡眠性血红蛋白尿(paroxysmal nocturnal hemoglobinuria，PNH)，经免疫抑制剂治疗后仅部分缓解。近1年贫血加重、输血依赖，考虑PNH活动性溶血所致，更换依库珠单抗治疗后贫血仍持续加重。详细询问病史发现患者慢性牙周感染，近1个月牙周疼痛溢脓伴发热。多学科讨论考虑慢性牙源性感染激活补体系统是PNH溶血加重的主要原因，急性感染影响了依库珠单抗的疗效。经多学科会诊制定治疗方案，给予静脉抗生素联合牙周冲洗、拔牙控制牙源性感染，同时继续按期输注依库珠单抗，患者临床症状好转，血红蛋白迅速上升，脱离血制品输注。该病例为通过多学科协作诊疗解决罕见病在新药物治疗中遇到的困难提供了经验参考
