A dissertation is a research report or scientific paper written by an author to obtain a certain degree. It reflects postgraduates’ research achievements and the educational quality of an institute, even a country. To construct an optimized quality evaluation system for postgraduate dissertation (QESPD), we summarized the influencing factors and invited 10 experienced specialists to rate and prioritize them based on fuzzy analytic hierarchy process. Four primary indicators (innovation, integrity, scientificity and normativity) and 16 sub-indicators were selected to form the evaluation system. The order of primary indicators by weight, was innovation (0.4269), scientificity (0.2807), integrity (0.1728) and normativity (0.1196). The top five sub-dimensions were theoretical originality, scientific value, data reliability, design rationality and evidence credibility. To demonstrate the effectiveness of the proposed system, a case study was performed. In the case study, it was demonstrated that the established two-index-hierarchy QESPD in this study was a more scientific and reasonable evaluation system worthy of promotion and application.

在卦象关系中,“错”指两卦“左右相错”,“综”指两卦“上下颠倒”。方以智的“错综”思想是对“相错”和“颠倒”关系的进一步凝练,展现了体用间的双向流行和双向主宰,这把“单向”的体用观推进到了“双向”的体用观:“体”从自身出发过渡为“用”,“用”也在“体”的统摄下过渡到“体”,在双向过渡中“体”和“用”都实现了自身。方以智的“错综”思想分为“十错”“十综”,“十错”包括“对舍”“对摄”“对入”“对夺”和“对即”,“十综”包括“绳衡”“太极”“善恶”“中旁”“往来”五个方面,展现了纵贯与横摄相统一、太极与阴阳双向互成、无善恶在为善去恶中、时空合一等思想。

It is difficult to determine the discharge stages in a fixed time of repetitive discharge underwater due to the arc formation process being susceptible to external environmental influences. This paper proposes a novel underwater discharge stage identification method based on the Strong Tracking Filter(STF) and impedance change characteristics. The time-varying equivalent circuit model of the discharge underwater is established based on the plasma theory analysis of the impedance change characteristics and mechanism of the discharge process. The STF is used to reduce the randomness of the impedance of repeated discharges underwater, and then the universal identification resistance data is obtained. Based on the resistance variation characteristics of the discriminating resistance of the pre-breakdown, main, and oscillatory discharge stages, the threshold values for determining the discharge stage are obtained. These include the threshold values for the resistance variation rate(K) and the moment(t).Experimental and error analysis results demonstrate the efficacy of this innovative method in discharge stage determination, with a maximum mean square deviation of Scrless than 1.761.

【目的】晚泥盆世弗拉—法门(Frasnian-Famennian,F-F)转折期是地质历史的一个关键时期,海洋生态系统发生了重大变化并造成了低纬度地区浅海底栖生物的大量灭绝。关于该时期的古气候、古海洋环境变化以及生物灭绝的成因机制研究目前已取得一定的进展,但仍然存在争议且各环境要素之间的相互作用尚不明确。【方法】在系统梳理F-F转折期古气候、古海洋环境变化研究现状的基础上,结合华南的研究实例探讨了F-F转折期的古海洋缺氧模式。【结果与结论】F-F转折期,气候在变冷的趋势下出现多次快速的暖—冷交替;缺氧范围和程度各地表现不一,但主要集中在低纬度浅海地区上Kellwasser层附近。因此,F-F生物危机并不是单一因素造成的。频繁、短暂的火山活动引起大陆风化作用增强,一方面导致了气候快速的暖—冷交替,另一方面促进了陆地向海洋中输入营养物质造成浅海的富营养化和缺氧。各个环境因素相互制约/影响对低纬度浅海地区生命造成极大的环境压力,最终导致了F-F生物危机。

随着低轨星座规模的不断扩张,本就相对匮乏的信关站资源变得更加紧张.为提高信关站天线的使用效率,提出一种混合克隆选择算法.首先,将卫星与信关站可见弧段转化为任务集合,将馈电链路切换问题转化为任务分配问题,并建立相应的数学整数规划模型;然后,将抗体编码为一组任务分配向量,结合启发式冲突消解规则,建立基于有向图最短路的解码方法,引入阈值参数降低解码的计算开销,提出基于自适应邻域选择的局部搜索算法,增强局部寻优能力;最后,搭建低轨星座馈电链路切换仿真场景,生成不同规模的算例来开展对比实验.仿真实验结果表明,所提出算法能够快速收敛到小规模算例的最优解,同时在大规模算例上比现有启发式算法表现出更强的求解能力和更稳定的性能,从而验证所提出算法的有效性.

文中以水为增塑剂,研究了不同卡拉胶/水溶液比例制备卡拉胶膜材料的热塑加工工艺。在此基础上,分别以Ca^(2+),Na^(+)和Mg^(2+)为交联剂,研究了盐离子的种类和浓度对ι型卡拉胶膜材料结构及性能的影响。结果表明,ι型卡拉胶可以在水的作用下,在热压机中热塑加工成型,当ι型卡拉胶/水质量比为1:0.8左右时成膜效果最佳。卡拉胶膜的结构性能受材料的塑化效果和盐离子的静电协同作用共同影响。随着离子半径减小(Ca^(2+)>Na^(+)>Mg^(2+)),盐离子与水分子的水合作用增强(Ca^(2+)+^(2+)),热塑性卡拉胶的塑化效果、膜透光性和热稳定性依次降低。与未改性卡拉胶相比,盐离子改性卡拉胶材料的拉伸强度和断裂伸长率均有所提高,说明盐离子的静电作用可以增加卡拉胶分子链之间的缠结,提高其力学性能;对比3种盐离子,Ca^(2+)浓度在0~50μL范围内,改性卡拉胶的拉伸强度和断裂伸长率由原来的4.94 MPa和6.4%分别提高到了10.18 MPa和9.2%;由于Ca^(2+)与水分子水合作用较弱及二价离子具有更强的静电作用,其改性卡拉胶材料的力学性能与其它2种盐离子相比效果更佳。
