water resource allocation for the Songhua River Region, China under the uncertainty of water supply
<span class="MedBlackText">Water resources allocation (WRA) is a useful and yet complicated topic in water resources management. The solution of WRA may be uncertain due to the uncertainty of the input, the structure itself, and the parameters of the models. So far, very few studies deal with the topic about how much these uncertainties influence the solution and how to adapt the situation. By using Dependent-Chance Goal Programming (DCGP), this paper built a WRA under the uncertainty of water supply for the Songhua River Region (SHRR) located in the northeast of China, one of China's most important commercial grain bases. Two sets of WRA results were obtained under the two ranges of uncertainty relative to bad (S1) and good (S2) water supply situations. Situation SI takes a higher water shortage rate and S2 takes a lower water shortage rate than the routine WRA results by the SHRR Commission's comprehensive plan, but all keeping the rate of water resources exploitation approaching or lower than the international standards. The result helps SHRR to make a more resilient decision to the change of water supply condition in meeting the national needs of Newly Increasing Yield of 10 × 10<sup>11</sup> Jin. </span
汉语反问句在会话交际中的信息调节功能分析
以不同的事件信息类型(A、B-events),即交际双方对信息的认识状态的不同为出发点,可以更好地对汉语反问句的使用情况进行描写,能够分析反问句如何协调共同背景从而推进信息的交流。基于不同事件信息类型的反问句的语言形式和语用功能在使用时显现出的特点,也可以判断反问句是否有疑,如果是基于Bevents的反问句,可能会有疑,而其他类型的反问句则无疑。另外,反问句在交际互动中呈现出礼貌程度的等级差异,其中基于AB-events的反问句礼貌程度最高,而基于O-events的礼貌程度最低。文章强调,对反问句的研究离不开它所处的真实言谈环境。国家社科基金重点项目(14AYY015)资

Research & Design of Shooting Training System on Android OS Platform
部队的射击训练常常都是实弹训练,使用人工报靶,这是对人力物力的巨大浪费,也存在一定的安全隐患,而且射手无法根据射击情况进行调整,这使得射击训练的效率低下。以光电技术和图像技术为代表的射击训练系统能替代传统射击训练报靶的人工操作,减少误报率,提高训练效率。尤其是随着计算机软硬件的发展,射击训练系统性能日渐稳定。但现有的射击训练系统的现状是功能上基本还停留在自动报靶上、使用时安装繁琐对环境要求很高,这限制了射击训练系统的推广与普及,而且也不能满足更高要求的射击训练。 本文致力于提供一套基于图像识别的射击训练系统。该系统能分析射手瞄准、据枪、击发等射击环节的表现,以指标的形式反馈给射手,并给出具有...The way shooting with bullets is usually used in troops’ shooting training. The method uses artificial target record. But this way cost large amount of unnecessary human and time and it’s not security. What’s more, shooter can’t get more information about shooting processing to improve shooting level. Shooting system based on photoelectric and image technology comes into being which will represent...学位:工学硕士院系专业:信息科学与技术学院_模式识别与智能系统学号:2322011115326
Design and Implementation of Payment Cipher Instrument Management System
近年来,我国社会经济快速发展,经济规模不断扩大,交易活动日益频繁,金融市场体系逐渐完善;市场的广度和深度不断拓展,综合国力显著增强,与其他国家和地区的经贸往来日益密切,人民币的国际地位不断提高。这一外部环境对中央银行的支付清算服务提出了新的、更高的要求。 现代化支付系统在提供快速、高效的支付清算服务的同时,如何保证其资金的安全性是一件头等重要的事情。使用支付密码及支付密码器是确保资金安全的一个重要、有效的途径。支付密码器能够保障单位的资金安全;提高结算效率,加快资金的到账速度;加强单位的财务管理和内部控制。随着支付密码器的推广,对支付密码器信息进行高效、便捷、安全可靠的管理是一件急需进行解决...In recent years,with the rapid development of economy, expanding economies of scale, transaction activities have become increasingly frequent, the financial market system gradually improved; the market continue to expand the breadth and depth, comprehensive national strength enhanced markedly, the increasingly close economic exchanges and trade with other countries and regions, the RMB's internati...学位:工程硕士院系专业:软件学院_工程硕士(软件工程)学号:X201023036
高等职业技术教育与普通高等教育:相互衔接抑或各成体系——若干国家和地区的经验与启示
高等职业技术教育与普通高等教育是性质不同的两种教育类型。当前我国高职院校通过“升格”、高职学生通过“专升本”与普通高等教育相衔接,缩小与普通高校的差别,这在一定程度上妨碍了高职教育的正常发展。然而考察若干国家和地区高职教育与普通高等教育的关系可以看出,这两类教育的沟通与衔接存在一定的现实性和必要性。因此,当前我国高职教育的发展要坚持两手抓,既要承认这两类教育衔接的必然性,更要不断提升高职教育的层次,进而完善职业教育自身体系
The Study of the Regional Circular Economy Index System and Examples
转变传统的经济增长方式,以循环经济崭新模式克服当前愈来愈严峻的资源、能源和环境的瓶颈,是我国现阶段经济社会发展的战略抉择。循环经济的实质被人们普遍解读为“3R”原则,即减量化、再循环、再利用。从物质流动和表现形态的角度看,它要求经济活动组织成一个“资源-产品-再生资源”的反馈式流程,其实现载体主要包括企业、工业园区和区域三个层面。如何在区域层面上全方位的建立循环经济体系,客观评价区域循环经济水平,制定区域循环经济发展战略,是当前亟待解决的研究热点。 客观评价一个区域循环经济发展的水平,制定区域循环经济评价指标体系是循环经济能健康发展的必要条件。同时制定区域循环经济评价指标体系是区域循环经济有...Strategic choice of the development of domestic economy and society is changing the mode of economic growth and overcome the bottle-neck of nore austere resource、energy and environment.

On the Nature of the party statute
国内学者对于“党内法规”的研究相对完善,在不同角度分别给出了不同的定义,综合的来看我们可以将“党内法规”这一个宏观概念诠释为包含了法律、纪律、行政规范以及制度建设等多个方面。在本文的研究中我们应该严谨地来探讨“党内法规”的本意,并从中找到我们是在什么意义上或什么层面上使用这个概念。这样便于我们有效地进行有关的科学探讨。 在当前理论研究中,学术界对于“党内法规”这个提法是有一定争议的。有学者认为,“由于‘党内法规’这一提法不能准确地将党的规章制度与国家法律法规相区别,建议用‘党的纪律’代替‘党内法规’的相关定义,此种提法是相对准确的。同时,部分研究人员从法学的角度给出了不同的定义,其认为法规与..."
