The She's Cultural Introspection and Economic Transformation

本文对畲族如何通过文化自觉来寻求经济的转型作了简要分析。一是从观念层面超越“耐劳杂作,弗事商贾”的传统农本意识、淡化“山野自足,于世无求”的族群封闭心理;二是从实践层面复兴与光大丰厚的山地农耕技术文化、梳理并激活沉寂、独特的民俗文化遗产。The text recommends briefly about the She how to search economic transformation through cultural introspection.One is from the conception level—the She must transcend their traditional farming consciousness which persevered in developing agriculture but was indifferent to the commerce.And their self-satisfaction,self-enclosed mind must become weaker.The other is from the practice level—aims at revivaling and glorifying the abundant mountain farming technic culture,organizing and activating the still but unique cultural legacy.2005年浙江省社科联重点课题:浙江畲族经济转型:传统与现代的整合[项目编号:05Z42

System development of PCB brush grinding machine based on force-controlled grinding with current feedback

传统磨削加工中大多采用一次磨削保持进给量不变的加工方式，加工过程中的工件材质、砂轮锋利程度等因素会产生变化，磨削力没有得到控制，会随着这些变化而变化，磨削效率低，导致不能保证加工质量。控制力磨削是一种能够控制切入压力为定值，通过测力反馈和机械运动等实现砂轮对工件的压力的一种磨削方式，其目的是控制磨削过程中的磨削力。在PCB制造过程中，需要一道磨削工序去除PCB表面毛刺和提高PCB金属镀层表面质量，为后续的工艺处理提供保证。由于PCB的原材料的不同，板薄变形大，需要磨削的磨削量较小，磨削过程中较大的磨削力，都会对PCB造成破坏。因此，对磨削中的磨削力进行有效控制是非常必要的。 刷磨机是一种专门...Traditional grinding method keeps the feeding unchanged in processing, the state of grinding wheel and material hardness and others will change. The grinding force is out of control and it cannot guarantee the machining quality. Force-controlled grinding can keep the pressure between the grinding wheel and workpiece at set value, and its purpose is to control the grinding force in grinding proces...学位：工学硕士院系专业：物理与机电工程学院机电工程系_机械制造及其自动化学号：1992008115291

Moving Towards the Market: Crop Planting and Economical Vicissitudes of a She Village

畲族是一个历史悠久的散杂居农业民族，其主体人口分布于我国广袤的东南山区。基于畲族经济较之东南区域经济严重滞后的现实，本文试图通过对浙江景宁畲族自治县敕木山区以惠明寺村为中心的畲族村落群经济变迁之田野调查，为畲族经济发展模式提出较有普遍意义的思考。 对畲族经济问题的关注，无论是从畲族研究的时代要求和学术使命，抑或从民族平等、社会和谐、城乡协调发展以及社会主义新农村建设等多维度来审视，均具有较强的现实紧迫性。 本文采取以惠明寺村为深度田野个案、以周边六个畲村为田野参照物的点面结合的调查方法，首先从畲族与市场关系的历史变迁切入田野对象（第一章），然后勾勒惠明寺村庄聚落变迁及农作物种植与经济变迁图...The She ethnic group is an agricultural one with an age-old history, with its main population living dispersedly among other different nationalities in the vast mountainous area in Southeast China.

Double-array Trie based on genetic algorithm and idea of Sherwood

对汉语信息处理中常常要涉及汉语词典查询,当所涉及的词典规模较为庞大时如何快速访问词典以获取词语知识便成为了一个需重点解决的问题。将阐述一种简单快捷的基于双数组TrIE(dOublE-ArrAy TrIE)原理的词典查询机制。该算法的查询时间为O(n)的线性时间(n为查询词条的长度),由此可见双数组算法在时间上存在着明显优势,但在空间耗费上却存在着浪费现象。前人提出了一些解决方案,其中主要的有:在构造双数组时采用一种启发式排序策略,即每一次都先处理当前分支节点最多的活动节点。考虑到这种启发式思想为确定性算法,容易陷入局部最优陷阱之中,因此在这种思想的基础上引入了舍伍德随机思想和遗传算法中常常运用到的变异思想,在改进算法空间利用率的同时也使得算法跳出了局部最优解的陷阱。In the Chinese information processing Chinese dictionary is enquired.When involved in a large scale of dictionary,how fast the visit to obtain knowledge of words will become a need to focus on resolving problems.This paper will outline a simple and efficient mechanism which is based on double-array Trie principle for the dictionary.For enquiries about the time of the al-gorithm is O(n)of linear time(n is the length of term enquiries).This shows that there is a clear advantage in double-array Trie.But there is a serious waste in storage of double-array Trie.Predecessors put forward some solutions.One of the major:Using a heuristic sort strategy.That is,each time the active node is dealt with first which has the largest branch nodes.Considering that such solution is a heuristic algorithm for deterministic algorithm,it will be easy to catch the trap of local optimal solution.On the basis of that kind of mentality,this paper introduces the idea of Sherwood random thoughts and mutation of genetic algorithms to improve the performance of double-array Trie

观察栀子苷改善非酒精性脂肪性肝病的效果,从游离脂肪酸探讨栀子苷调节非酒精性脂肪性肝病的作用机制。健康雄性Wistar大鼠40只,随机分为4组:正常组、模型组、栀子苷组和血脂康组,每组大鼠10只,正常组大鼠给予正常大鼠饲料喂养,其余3组大鼠均采用高脂饲料喂养以诱导非酒精性脂肪性肝病,造模时间为8周,从第5周起至第8周末,栀子苷组和血脂康组分别灌服相应的药物。记录大鼠体重、肝湿重、脂肪质量;用相应方法检测肝组织TG,FFA,FAS,AMPK,ACCase及Malonyl-Co A含量,血清CHO,LDL-C的含量,血清AST,ALT的活性;观察肝脏组织肉眼及病理变化(HE染色法)。结果显示,与正常组相比,模型组大鼠的体重;肝湿重;脂肪重;血清CHO,LDL-C,ALT,AST;肝组织TG,FFA,FAS,ACCase及Malonyl-Co A含量皆显著升高(P<0.01);肝组织AMPK活性显著降低(P<0.01),肝组织肉眼外观及病理切片脂肪变性明显,并出现炎症损伤;与模型组相比,栀子苷组大鼠体重、脂肪质量、肝组织FFA含量、血清ALT,AST活性均显著降低(P<0.01),肝湿重,肝组织TG,FAS,ACCase及Malonyl-Co A含量明显降低(P<0.05),肝组织AMPK活性明显增多(P<0.05),肝脏肉眼外观及病理学表现均有所改善;与模型组相比,血脂康组大鼠的肝湿重、脂肪质量、肝组织TG,FFA和血清LDL-C水平明显降低(P<0.05);与血脂康组相比,栀子苷组大鼠的体重、脂肪质量、肝组织FFA含量均显著降低(P<0.01),其他方面无明显差异。结果表明,栀子苷具有显著的改善高脂饮食诱导的大鼠非酒精性脂肪性肝病的药理效应;其改善大鼠非酒精性脂肪性肝病的游离脂肪酸代谢是通过调节"AMPK-ACCase-Malonyl-Co A-FFA"轴来实现的。To observe the effect of geniposide on non-alcoholic fatty liver disease( NAFLD),and discuss the mechanism of geniposide for NAFLD from the aspect of free fatty acid,forty healthy Wistar male rats were randomly divided into normal group,model group,geniposide and Xuezhikang group. The rats in normal group were fed with normal diets,and the rats in other 3 groups were given with high-fat diet for 8 weeks to induce the NAFLD models. From the week 5 to end of week 8,the rats in geniposide and Xuezhikang group were intervened with corresponding medicines. The body weight,liver wet weight,and fat weight of the rats were recorded.Visual and pathological changes in hepatic tissues were observed with HE staining. The contents of TG,FFA,FAS,AMPK,ACCase and Malonyl-Co A in hepatic tissue,contents of CHO and LDL-C in serum and activities of AST and ALT in serum were detected by using corresponding methods. The results showed that the body weight,liver wet weight,and fat weight of the rats,CHO,LDL-C,ALT and AST levels in serum,TG,FFA,FAS,ACCase and Malonyl-Co A levels in hepatic tissues of the rats in model group were significantly higher than those in normal group( P < 0. 01),while AMPK activity was significantly lower than that of the normal group( P < 0. 01),with obvious visual and pathological steatosis in hepatic tissues,and inflammatory injury occurred in model group. Compared with the model group,body weight of the rat,fat weight,levels of FFA in hepatic tissues,ALT and AST activities in serum,liver wet weight,TG,FAS,ACCase and Malonyl-Co A levels were significantly decreased in geniposide group( P < 0. 01),while the AMPK activity in hepatic tissues was significantly increased( P < 0. 05),with improvement in visual and pathological performance.Compared with the model group,liver wet weight,fat weight,TG and FFA levels in hepatic tissues,and LDL-C level in serum were significantly decreased in Xuezhikang group( P < 0. 05). Compared with Xuezhikang group,the body weight of rat,fat weight and FFA level in hepatic tissues were significantly lower in geniposide group( P < 0. 01),but with no significant difference in other aspects. These findings indicated that geniposide was highly effective in improving the pharmacological effect of NAFLD induced by highfat diet,and the mechanism was achieved through AMPK-ACCase-Malonyl-Co A-FFA axis.国家自然科学基金项目(81274155;81503529);; 福建省自然科学基金项目(2014J01374);; 福建省高等学校新世纪人才计划项目;; 厦门市科技计划项目(3502Z20134020);; 福建省中医药科研项目(WZPW201308

焊接热输入对TMCP和QT态高强钢接头冲击韧性的影响

为高强钢在低温环境下的应用提供试验数据和建议，本文重点围绕焊接热输入和接头母材的不同交货状态这两个关键影响因素，选取控轧控冷（TMCP）和调质（QT）两种交货状态的20 mm厚Q550D和Q690D高强钢，分别进行1.0 kJ·mm-1、1.5 kJ·mm-1和1.9 kJ·mm-1三种常见的气保焊焊接热输入的接头制备、韧性试验检测和对比分析，进行了不同交货状态下对接接头的母材、焊缝区和热影响区（HAZ）的夏比冲击功及其变化规律，以及韧脆转变温度的研究。结果表明：焊接热输入对接头各位置冲击韧性的影响不明显，而交货状态不同则接头呈现出不同的冲击韧性，其中QT态钢板焊接接头热影响区的冲击韧性要优于母材和焊材，而TMCP态钢板焊接接头热影响区的冲击韧性则低于母材和焊材；对控制工况下的韧脆转变温度的研究表明，本文所用的高强钢低温敏感性较好
