Study on the Legal Construction of Ecological Environmental Protection in Tibetan Mining Area

环境与资源的议题，历来是人类社会长期关注的焦点。矿产资源的开发像支锋利的长矛，拉动经济效益的同时对生态环境造成了致命的污染和破坏。西藏作为我国的矿产资源大省和重要的生态安全屏障区，其生态环境的脆弱性决定了该地区矿区生态环境保护的迫切性与必要性。20世纪末开始，我国在探索生态环境保护的法律路径上取得了突破性的进展，陆续出台相关法律文件以遏制生态环境的持续恶化。但是由于立法笼统分散、执法僵化被动、司法停滞不前等各种原因，导致西藏矿区生态环境保护成效不明显且举步艰难。为进一步完善西藏矿区的生态环境保护法制建设，本文将通过分析西藏矿区生态环境保护法制现状的不足，借鉴美国、澳大利亚、加拿大等发达国家的矿...Environmental and resource issues are the common concern in world today. Exploitation of mineral resources is like double-edged sword. On the one hand, mineral resources could promote economic development, but on the other hand, it’ll destroy the local ecological environment. Tibet is rich in mineral resources and it is an vital ecological buffer area. The frangibility of its ecological environmen...学位：法学硕士院系专业：法学院_环境与资源保护法学学号：1362014115021

On the Synonym Discrimination Boxes in English-Chinese Learner’s Dictionaries

对于广大的英语学习者来说，学习过程中最困惑的问题之一就是英语同义词的辨析。因为一方面，英语中有很多同义词；而另一方面，同义词辨析的能力已经成为考察英语水平的一个关键指标。英汉学习型词典中的同义词辨析专栏是英语学习者一种重要的参考工具，然而在现今的英汉学习型词典中，同义词辨析专栏并不尽如人意。因此本文旨在优化学习型词典中的同义词专栏。 本文首先对前人在同义词方面的研究进行了文献综述，结果发现尽管语料库技术已经运用到词典编纂，也被用于同义词辨析，但这三方面从未结合起来研究，也就是说，语料库的成果从未被运用到词典中的同义词专栏。因此本文尝试在研究中将这三方面结合起来。 接着文献综述本文介绍了在研...For many Chinese EFL learners, one of the most puzzling problems in English learning is brought by synonyms. Because on the one hand, they are abundant in English; on the other hand, the ability to distinguish synonyms has been regarded as a key factor of English proficiency. When learners need to find the information about differences between synonyms, the synonym discrimination boxes in English-...学位：文学硕士院系专业：外文学院英语语言文学系_英语语言文学学号：1202008115283

Optimization of solid culture conditions for TNF-α inhibitor qiaonanmycin via response surface methodology

目的利用响应面法对潜在的Tnf-α抑制剂桥南霉素固态发酵培养基进行优化。方法用HPlC做检测方法,以桥南霉素的洗脱峰面积为指标,先通过PlACkETT-burMAn(P-b)实验筛选出影响固态发酵产量的主要因素,进而进行单因素优化实验和响应面中心组合设计实验,确定主要影响因素的最佳浓度,得到最优的固体发酵培养基组成。结果优化后的发酵培养基组成:土豆400g/l、葡萄糖35g/l、蛋白胨10.5g/l、(nH4)2SO4 0.6g/l。按此配方固态发酵10l,对得到的粗提物进行HPlC检测,桥南霉素的实际产量为4.3Mg/l,与模型的理论值基本相符,较优化前的产量1.5Mg/l提高了186.7%。结论响应面方法是一种有效的培养基优化方法,经此优化方法桥南霉素的产量得到了较大的提高。Objective The solid fermentation culture conditions of compound qiaonanmycin were optimized via response surface methodology.Methods Based on quantitative detection method of qiaonanmycin by HPLC, the key fermentation factors were determined via P-B test, then their optimized concentrations were confirmed through response face method.Results The optimum solid fermentation culture medium compositions of qiaonanmycin were: potato 400g/L, dextrose 35g/L, peptone 10.5g/L, and(NH4)2SO4 0.6g/L.Under this condition, the yield of qiaonanmycin was 4.3mg/L, resulting in a 186.7% increase comparing with original production yield, and the optimized yield was consistent well with theoretical value predicted by response face method.Conclusion The optimized solid fermentation culture conditions were reliable and repeatable, it was warranted for large-scale fermentation process.中央高校基本业务费(No.2010121092); 厦门市科技计划项目(No.3502Z20123010

Analgesic Effects of Active Exercise and Passive Exercise and Their Mechanisms

主动运动和被动运动可以有效缓解各种急性疼痛和慢性疼痛,且主动运动诱发的镇痛效果强于运动参数相似的被动运动.文章在讨论运动镇痛机制的基础上,探讨了主、被动运动镇痛效果存在差异的原因.具体来说,通过比较两种运动传导运动信息的下行通路和传导躯体感觉/本体感觉的上行通路,论述了主、被动运动在生理(外周神经系统和中枢神经系统)和心理(情绪和认知)层面上镇痛机制的异同.由于被动运动缺少运动下行控制且肌肉激活程度小,其在外周镇痛物质含量和皮层水平上对疼痛的调控弱于主动运动.此外,被动运动相比主动运动不易诱发积极情绪,较难转移对疼痛的注意力,缺乏身体掌控感并拥有较低的身体归属感,进而导致较弱的镇痛效果.最后,文章指出了目前本领域研究的局限性,并对运动镇痛未来的研究方向和方法提出了建议.</p
