    当前大部分的微型低能耗电子设备以及微机电系统(MEMS)器件使用传统的 体积较大的外接电源供能,这就限制了这些微型器件在很多方面的应用。一个选 择就是将微型电源与这些微器件设计集成在同一个芯片上。本论文主要开展了与 微电子技术兼容的全固态的微型锂离子电池的研究,包括相关的薄膜材料、固态 电解质-电极界面研究以及微型锂离子电池制备工艺等方面。 在电极膜制备方面,首先使用射频磁控溅射法制备LiCoO2薄膜,研究了不 同的溅射基底温度和后续的退火温度与薄膜形貌、晶态结构以及电化学性能的联 系。LiCoO2薄膜从非晶态向晶态转变的能垒随着溅射时基底温度的增加而降低。 后续的高温退火以及...Most low-power electronic and microelectronmechanical system (MEMS) devices designed today use conventionally macroscopic external power supplies. This places limits on the functionality of these microdevices in many applications. An alternative solution is to design power sources at a microscale, which can be integrated together with these microdevices on the same chips.

    “海峡西岸经济区”概念的提出,在为该地区物流业发展创造新机遇的同时,也提出了新问题。海峡西岸经济区物流业目前究竟处于怎样的发展水平,有怎样的竞争优势,存在怎样的问题,针对这些优势和问题,我们又应该如何应对,这是本文研究的重点。 本文从两个角度来评价海峡西岸物流业的发展水平:纵向,通过对海峡西岸经济区主体福建省最近10年来物流业的综合评价,得出海峡西岸经济区物流业总体呈现指数状发展速度的结论;横向,通过对海峡西岸经济区21个城市物流业的综合评价,得出海峡西岸经济区物流业城市间发展不平衡,制约了海峡西岸经济区内部协调发展。 最后运用SWOT分析,确定出海峡西岸经济区面临的优势、劣势、机遇和威胁...The conception of the Economic Zone on the Western Coast of the Taiwan Straits puts forward new opportunities and problems to the area. On one hand, with the development of logistics industry, the promotion of the position of Yangtze River delta and Pearl River delta injects new energy into the southeast coast economic development.

    肿瘤的发生机制和治疗一直是医疗卫生领域的难题之一。随着分子生物学技术的发展,肿瘤的发生机制逐渐被揭示,为肿瘤的预防,控制和治疗提供了新的依据和途径。肿瘤是一种高度异质性的疾病,从分子生物学角度来讲,涉及非常多的基因改变,包括基因突变,表达,表观遗传学等多个领域。不同的肿瘤类型,不同的肿瘤患者,不同的发病部位,不同的组织学类型都涉及了不同基因的不同改变形式,而这些改变形式与肿瘤患者的预后及对治疗的反应性相关。因此,针对肿瘤异质性,以患者分子生物学状态为依据的个体化治疗应运而生。从肿瘤的预防,早期诊断到肿瘤的控制和治疗等一系列过程中都需要对患者的分子生物学状态进行深入的分析后才能给出具体的方案。而...Tumorigenesis and treatment is one of the difficult issue for medical treatment and public health system. As the development of molecular biology, the mechanism of tumorigenesis is discovered gradually and provide new approach for the prevention, control and therapy of tumor.

    内容摘要 本文旨在从正当法律程序发展的视角研究中国行政立法程序的正当性问题。尽管在过去,可能由于行政立法程序产生较晚的缘故,正当法律程序没有被适用于行政立法程序领域,但正当法律程序的适用既然能够从最初的司法领域过渡到行政领域和立法领域,其最终必然将被适用于行政立法领域,并形成正当行政立法程序。基于这一认识,本文从正当行政立法程序的内涵、历史演进、宪法制度基础、程序价值以及其中国化等方面,对正当行政立法程序进行了较为系统的理论探讨。除了导论和结语以外,本文共分为五章。导论部分介绍了选题缘由、研究意义、研究思路、研究方法和可能的创新之处,并梳理了中外学者对正当行政立法程序相关问题的研究现状。...ABSTRACT The thesis endeavors to study the legitimacy of China's administrative legislation procedure from the perspective of the development of “due process of law”. Although in the past, “due process of law” has not been used in the field of administrative legislation, as the administrative legislation procedure formed late, the application of “due process of law” is able to transit from the ...学位:法学博士院系专业:法学院_法学理论学号:1362009015314

    目的 探讨不同血糖控制方案对脑出血术后应激性高血糖患者预后及血糖的影响。方法 采用回顾性研究方法将2015年6月~2016年5月入住我院重症医学科的52例脑出血术后应激性高血糖患者根据血糖控制方案的不同分为A组(n=25)和B组(n=27),A组采用静脉单次推注,B组采用持续静脉泵注。比较两组的28 d生存率、格拉斯哥预后评分、血糖达标率、达标时间、血糖监测次数、低血糖发生率、血糖水平和血糖变异度指标的差异。结果 两组的28 d生存率、血糖达标率、达标时间、低血糖发生率比较,差异无统计学意义(P〉0.05)。A组的格拉斯哥预后评分显著高于B组,差异有统计学意义(P〈0.05)。A组的血糖监测次数显著少于B组,差异有统计学意义(P〈0.05)。A组的血糖最大值(Glu_(max))和血糖差值(Glu_(dif))均显著小于B组,差异有统计学意义(P〈0.05)。结论静脉单次推注胰岛素能够改善脑出血术后应激性高血糖患者的神经功能预后,可以降低入ICU后血糖最大值和血糖差异。Objective To investigate influence of different blood glucose control programs on prognosis and blood glucose in patients with intracerebral hemorrhage after operation together with stress hyperglycemia.Methods A retrospective study was conducted,and 52 patients with stress hyperglycemia after cerebral hemorrhage in our hospital from June 2015 to May 2016 were divided into group A (n=25) and group B (n=27) according to different blood glucose control programs.Group A was treated with intravenous bolus injection,and group B was treated with continuous intravenous pump.The 28 d survival rate,the Glasgow outcome score,the blood glucose compliance rate,the standard time,the fre- quency of blood glucose monitoring,the incidence rate of hypoglycemia,blood glucose levels and blood glucose variabili- ty indexes were compared between the two groups.Results There was no significant difference in 28 d survival rate,the blood glucose compliance rate,the standard time,the incidence rate of hypoglycemia between the two groups (P〉0.05). The Glasgow outcome score in group A was significantly higher than that in group B,with significant difference (P〈 0.05).The number of blood glucose monitoring in group A was significantly less than that in group B,with significant dif- ference (P〈0.05).The Glu., and Glu~f in group A was significantly less than that in group B,with significant difference (P〈O.O5).Conclusion Intravenous single bolus insulin injection can improve the prognosis of nervous function in pa- tients with intracerebral hemorrhage after operation together with stress hyperglycemia,and can reduce the maximum blood glucose and blood glucose difference after ICU.广东省东莞市医疗卫生类科技计划一般项目(2015105101220
