浅述我国离婚法定理由

离婚自由是婚姻自由的一个重要方面,我国的《婚姻法》给出了法律规定,将夫妻感情破裂作为离婚的法定理由,并将调解作为前置性程序。但夫妻感情破裂难以界定,不能涵盖离婚理由的各个方面。本文试图从法定理由简要剖析,探讨我国新修改的离婚法定理由的不足,并进行了对策分析

Study on the construction of patient’s Right of Informed Consentin China

患者知情同意权是指患者在充分理解必要的医疗信息后，有自主决定是否接受医疗措施的权利。知情同意权是患者在医疗行为中最基础的一项权利，在各国的司法判例和立法实践中得以不断地扩充和发展，并被越来越多国家的司法所承认和保护。 长期以来，我国的医疗立法和医疗纠纷的司法实践都偏向于对医生、医疗机构的保护，对患者的权益保护重视不足，是导致医疗纠纷增多、医患关系紧张的重要原因。本文从患者知情同意权的产生和发展入手，阐述了患者知情同意权的涵义，从不同角度介绍其理论渊源，分析了知情同意权的制度框架，最后结合我国患者知情同意权的立法现状，借鉴其他国家有关患者知情同意权的立法经验和实践，对我国患者知情同意权制度的建...Informed consent of patients is necessary in patients with a full understanding of medical information, to have independent medical measures to decide whether to accept. Informed consent is the most basic medical practice a right of judicial precedents in national and legislative practice to continue to expand and develop, more and more countries and was recognized by Justice and protection. ...学位：法律硕士院系专业：法学院法律系_法律硕士(JM)学号：1362008115079

支架表面的光滑度对家兔髂动脉内膜增生的影响

目的研究金属支架表面的光滑程度对兔髂动脉模型内膜增生的影响,探讨动脉支架植入术后再狭窄的影响因素。方法选择30只家兔对侧髂动脉作为自身相互对照,随机在一侧髂动脉植入30枚表面光滑支架(组1),而在另一侧植入30枚表面粗糙的支架(组2)。术后5个月处死家兔,并将所有髂动脉取出,对支架部位进行形态学分析。结果组1兔髂动脉测量段内膜面积小于组2:0.69±0.30对1.48±0.32mm2(P<0.05)。组1的内膜及中层横截面积的比率小于组2,1.27±0.47对3.08±0.89(P<0.01)。结论粗糙的支架表面明显增加支架内的内膜增生

现代企业理财与企业社会责任的关系

主持人:"企业社会责任"是西方人创追的概念,英文为 Corporate Social Responsibility。20世纪70～80年代,企业社会责任问题得到西方学术界、实务界和社会公众的普遍关注,并形成一场轰轰烈烈的运动。该项运动从根本上调整了企业与社会的关系,迄今,两者都在受益。从20世纪80

氧离子辐射对体外人精子自发化学发光、运动性、顶体反应和存活率的影响(英文)

我们研究了不同剂量(0,0.25,0.5,1,2,4,8,16,32,64Gy)3.17MeV/u氧离子对体外人精子自发化学发光(SCL)、运动性,顶体反应(AR)和存活率的影响。结果表明,精子SCL随辐射剂量明显增强,最低有效剂量为0.5Gy;精子运动性在0.5—2Gy,AR在0.5—4Gy辐射组均明显高于其对照组,但均随辐射剂量的进一步增加而明显降低;在0.25—8Gy剂量之间,精子存活率与其对照组相比无明显变化,但当剂量进一步增加至16—64Gy时,存活率急剧下降。这些结果提示,低剂量重离子辐射能对精子运动性及AR等功能产生兴奋效应。而大剂量则明显抑制这些功能,甚至造成精子死亡。其作用机制可能与重离子辐射诱导的自由基反应有关。Effects of 16O+6 ion irradiation with different doses on human sperm spontaneous chemilu-minescence (SCL), motility, acrosome reaction (AR) and viability were examined.

The effects of the microstructure on their properties of electrochemical insertion were investigated. The carbon nanotube, which preparaed by catalytic decomposition of acetylene using iron nanoparticles as catalyst, showed a low degree of graphitization. There were large amount of the defects such as wrinkled graphite sheets, interstitial carbon atoms, unorganized graphitic structure and microcavities in this nanotube and lead to a higher specific capacity, which is 640mAh/g at first cycle. But the defect structure resulted in a low cycling stability. After 40 cycles, its capacity was degraded to 58% of the original one. The carbon nanotube, which prepared by the pyrolysis of ethylene catalyzed by iron oxide nanoparticales, showed a high degree of graphitization and a rule microstructure. The well-graphitized carbon nanotube exhibited a low electrochemical storage lithium capacity, which is 282mAh/g at first cycle. But it showed a good cycling stability. After 40 cycles, the capacity maintained 86% of the original capacity. The influences of the temperature and charge/discharge current densities on their electrochemical storage lithium capacities were also discussed.浙江省自然科学基金! (No .2 0 0 0 53);; 厦门大学固体表面物理化学国家重点实验室开放基金&
