    假眼小绿叶蝉(Empoascavitis)属半翅目(Hemiptera),叶蝉科(Cicadellidae)是中国茶区分布最广、危害最重的一种茶树害虫,一般可造成减产15%左右,严重时甚至可达50%。所以,如何有效防治该害虫是当前的研究热点。尽管目前对该物种有较多的研究,但就其分类归属问题一直存在争议;此外,在防治方法的建立方面很难兼顾生态安全性和防治有效性。据此,本文综合运用形态学和分子鉴定技术对该物种进行重新描述;应用分子生物学和组织病理学技术探讨了两种茶树抗性蛋白(Cs-Cystatin、Cs-RIP)对该害虫的毒性作用;以期为相关研究工作提供样本标准和参照以及为开发新型防治技术提供技术...Empoasca vitis (Hemiptera,Cicadellidae) is a major insect pest threatening tea production throughout China. E.vitis cause a decreased of 15% in tea yield, even up to 50%. Thus, study how to effectively control the pest is the research hotspot currently. Nowadays, there are many studies about this species but the classification of this species has been controversial. In addition, it is difficult to...学位:理学硕士院系专业:生命科学学院_动物学学号:2162011115240

    内容摘要业务流程再造(BusinessProcessReengineering,简称BPR)是20世纪90年代在国外企业管理界兴起的一种先进管理理论。BPR打破传统的分工理论和层级组织体系,在国外企业得到了较为普遍的应用。中国企业界也在积极探索与企业自身实际相结合的BPR模式,以期在企业效绩和持续发展方面均获得较大程度的改善。成功进行BPR是企业获得竞争优势的重要管理战略。中国近现代邮政发展已经走过百年历程,目前正处于改革发展的关键时期。本文通过引入BPR的理论思想,从邮政业务体系重组、组织结构重新设计和业务流程优化与再造等三个方面,提出邮政企业进行业务流程再造的应用框架和主要模式,以期进一步...Abstract Business Process Reengineering (abbreviated, BPR) is an advance management theory abroad rising in 90th, 20th century. It broke the traditional job-dividing theory and hierarchy organization system, and was applied popularly in foreign firms. China Enterprises are exploring a BPR model combined with their own practice, aiming at winning great improvement in performance and sustainabili...学位:工商管理硕士院系专业:管理学院工商管理教育中心_工商管理硕士(MBA)学号:X20021513

    在经济、军事、社会信息化的今天,信息的作用和地位越来越突出,能否掌握并且控制信息资源已然成为国家稳定的决定因素。目前,人们对于信息安全问题的认识大多停留在防范来自外部的黑客攻击和病毒对内部网络的侵害,而对来自内部网络的危害重视不足,认为仅仅通过防火墙和防杀病毒软件就可以确保内网安全。但事实并非如此。根据我国国家信息安全评测认证中心的调查结果显示,信息安全问题的80%来自内部。 随着电子政务的开展,电子政务局域网内泄密事件屡有发生。如何能够及时准确的检测出涉密信息并以此预防,成为当今电子政务发展的一块拦路石。本文建立了一种利用搜索引擎工作机制的局域网涉密信息监控系统,通过爬虫爬行局域网内WEB...Informations play an important role in the status and function of development of Economic, military and social informationization. How to master and control the information resources have been the decisive factors of national stability.

    随着我国融入世界经济体系的潮流中,我国学校也必然要与世界经济体系接轨,对于面对的诸多机遇和挑战,我国学校必须要吸收国外先进的科学技术来提高自身的竞争水平。学校在数字化、信息化方面的调入力度逐渐增加,各种应用系统也逐渐产生并逐渐成熟,但对于教师绩效考核方面的建设相对较差。学校的考核的标准不统一,考核的体制不规范,很多的工作都是根据人的感觉走,这样的工作效率很难做到对每个教师绩效考核的公平公正,降低了教师的工作积极性。因此,建设一个规范的教师绩效评估系统来实现学校对教师绩效的考核成了一个非常重要的事情。 本文通过对我国学校中教师绩效评估体系的实际调查研究,结合教师绩效评估的实际需求进行研究,思想...As China's integration into the world economy trend, our school is also bound to convergence with the world economic system, for many opportunities and challenges facing, our schools must absorb advanced foreign technology to improve their competitive level.

    内生增长理论认为,外商直接投资(ForeignDirectInvestment,FDI)对东道国经济的影响是多方面的。作为资本、技术和管理知识的复合体,与单纯的货币资本相比,FDI具有更强的外部性,能够通过技术和知识的溢出促进东道国技术进步,影响东道国经济的长期增长。上世纪90年代初,我国开始实施“以市场换技术”的引资战略,试图通过开放国内市场来吸引国外先进技术,进而利用FDI的溢出效应提高国内企业的技术水平。该战略实施10多年来,我国成了全球实际利用FDI最多的发展中国家,外资企业在我国也获得了巨大的市场份额。那么,我国引进外资的重要政策目标——获取FDI的溢出效应是否实现了?进一步,又有哪...The theory of endogenous growth hold that Foreign Direct Investment (FDI) can influences the host countries' economy through different ways. As the syntheses of capital, Technology and Management Knowledge, FDI possesses more externality than pure money capital.

    酵母菌既具有细菌单细胞、生长快、能形成很好的絮体、适应于各种不同的反应器等特点,又具有真菌细胞大、代谢旺盛,耐酸、耐高渗透压、耐高浓度的有机底物等特性,因而可用于多类难处理有机废水的处理,并且具有处理效率高、污泥负荷高、占地面积小、剩余污泥可回收用作饲料蛋白等特殊的优越性。酵母菌废水处理技术有望成为常规好氧和厌氧处理技术的重要补充而在工业废水治理中发挥重要作用。Yeast cells have both the virtues of bacteria (living in single cell, growing fast, forming good flocs and suitable for various bioreactors) and fungi (high tolerance to acids, high salt and high concentration of substrates). When used in wastewater treatment, the yeast technology permits a high COD load and a small bioreactor and could endure various bad wastewater environments such as acid, high osmotic pressures and so on. Its residual sludge normally contains high protein and can be used as good additives in animal food. So this technology is expected to be a promising supplement for traditional aerobic and anaerobic wastewater treatment techniques to solve some intractable problems in industrial pollution.国家自然科学基金资助项目(50278095
