    摘要 行政调解作为一项重要的非诉争议解决途径,在我国专利的行政保护中扮演着重要的角色。但在目前实践中,因调解效力有限,调解后的调解协议缺乏强制执行力,不可避免的出现行政机关的调解职能被不断弱化等问题。为此,我们需进一步开发专利侵权纠纷行政调解的制度潜力,提升专利司法保护和行政保护的有效衔接,规范专利侵权纠纷行政调解司法确认机制,并对该制度进行改进以期充分发挥行政调解的作用,实现行政资源和司法资源的整合,完善我国专利侵权纠纷解决机制。 专利侵权纠纷行政调解协议司法确认机制发展于人民调解协议司法确认机制,是指纠纷双方当事人经过专利行政主管部门的调解,达成了专利侵权纠纷调解协议后,为赋予该协议强...ABSTRACT Administrative mediation, as an important non - litigation dispute resolution, plays an important role in the administrative protection of our patent. However, in the current practice, due to the limited effect of mediation, mediation after the mediation agreement lack of enforcement, inevitably appear the administrative organs of the mediation function is weakened and so on. To this end...学位:法律硕士院系专业:法学院_法律硕士学号:1302014115026

    较之那些高产的“60后“批评家,柱林论著的数量是可以用“少“来形容的,一本专著、二十余篇论文,这是我们能看到的柱林论著的全部。论著少,并不是因为柱林懒惰———事实上柱林一直是

    The research on foreign students' Chinese parenthesis study

    Get PDF
    在汉语教学与研究中,插入语(又称独立语)一直以来没有得到足够的重视。究其原因,主要是插入语不作句子成分,也不与句子中各个成分发生结构上的关系,往往被当作句子中可有可无的成分,忽略了它的表意作用和篇章连接功能。本文侧重从语言篇章教学的角度,在比较汉语母语者与留学生插入语使用的基础上指出:插入语是语言表达中的重要成分。没有插入语介入,在交际中就会出现话语断层,语言态度模糊,语言信息不明等现象,从而引起交际偏差,深入地进行插入语研究并将之应用于语言教学实践,具有重要意义。由于以往插入语本体研究的不足,在语言教学特别是对外汉语教学中,插入语这一语言项目的教学存在一些缺陷。本文通过对留学生汉语插入语使用...In the Chinese teaching and researching in the past, parenthesis haven’t been paid reasonable attention. The cause of this appearance may be: Parenthesis is not the component of sentence, and it has no structural relation with components of sentence. It looks like a useless dot in our language. In fact, parenthesis has important function in paragraph’s cohesion and coherence. It also gives the way...学位:文学硕士院系专业:人文学院中文系_语言学及应用语言学学号:20030101

    摘要传统的设计工具始终是以几何造型为核心,对工程设计考虑较少,设计流程的优化,设计意图的捕捉,经验参数的重用都缺乏相应的解决方案。而在特定行业中,产品的开发往往是建立在已有产品开发经验和工程制造经验基础之上的,因此对这些产品的开发而言,没有哪种技术能比知识工程技术(KnowledgeBasedEngineering简称KBE)更具应用价值。KBE是领域专家知识的继承,集成,创新和管理,是CAX技术与AI(人工智能)技术的集成。大多数工业产品的设计开发要求设计者具有较高的专业技术素养和丰富的实际设计经验,培养一个专家级的设计人员需要很长的周期,并且一旦人员流动,相应的经验也被带走。通过KBE技术...Abstract The traditional design tool always takes shapes modeling as core, have less consideration to the engineering design and lack good solution in design process of excellent turn, catch design intention and experience parameter of reuse.But in the particular profession, the development of product usually foundation on product development experiences and engineering manufacture experiences whi...学位:工程硕士院系专业:软件学院_工程硕士(软件工程)学号:X20044001
