Abstract:
传统的阻塞式多线程服务器体系在面对大数据量、长连接、高并发请求时常常遇到性能方面的局限,而新兴的Nodejs通过将最大连接数量更改到单个系统的流量来解决以上的瓶颈。本文旨在从工作方式和运行性能上探究Nodejs搭建的异步非阻塞服务器与传统的阻塞多线程服务器的区别。进而说明Nodejs在处理大数据量、长连接、高并发请求时的优越性。
The old blocking multi-threaded server architecture always encounters the limitations of performance when it faces these problems such as large data, long connection, high concurrent requests. Nodejs will change the maximum number of connections to the flow of a single system to solve the bottleneck. This article aims to explore the difference between asynchronous non-blocking server and blocking multi-threaded server from work and running performance. Then it explains the superiority of Nodejs in processing large data, long connection and high concurrent requests.

Abstract:
2012年3月13日,美国、日本和欧盟就中国稀土、钨矿及钼矿的出口限制措施向世界贸易组织争端解决机构起诉,随后7月23日WTO争端解决机构决定成立专家组审查此案,2014年3月26日,专家组报告公布,随后4月17日、25日中国分别针对美国、欧盟及日本提出上诉,同年8月7日,WTO公布上诉机构报告,宣告中方败诉。本文通过对稀土案所涉及的法律问题进行研究,着重分析中国承担的WTO义务、GATT1994第20条“一般例外”条款的解释与援引、国家经济主权与WTO规则的博弈等,剖析中国在该案件中暴露出的国内法规政策与WTO规则的冲突、对WTO规则及其适用的理解不充分、在争端解决的诉讼程序中举证能力不足等方面的问题,探讨国家在WTO框架下如何运用WTO规则维护国家经济主权。
On March 13, 2012, the United States, Japan and the European Union prosecuted China in export restrictions of rare earth, tungsten and molybdenum mine to the WTO Dispute Settlement Body. On July 23, WTO Dispute Settlement Body decided to set up expert group to review the case. On March 26, 2014, the panel report was released; hereafter on April 17th China appealed United States to Appellate Body, and on 25th China appealed Japan and European Union to Appellate Body. On August 7, 2014, WTO Appellate Body report was released, declaring Chinese lost. This article will analyze the legal issues involved in the case of rare earth research, the obligations of China to WTO, interpretation and quote of Article 20 of the GATT 1994, the game of national economic sovereignty and WTO Rules. Through analyzing the conflict exposed from China’s domestic laws and policies in this case with the WTO rules, the insufficient understanding of WTO rules, the lack of capacity in the proceedings the burden of proof in dispute settlement, this article will discuss how to use WTO rules to safeguard the country’s economic sovereignty under the WTO frame- work.
预防性侵权责任和补偿性侵权责任的法经济学思考


- , 2017,
Abstract: 摘要 侵权法应通过相关制度设计创设一套能够为潜在侵害人和受害人提供充分激励、促使潜在侵害人和受害人采取最优注意水平和行为水平,从而避免事故发生的预防激励机制。预防性侵权责任和补偿性侵权责任作为我国《侵权责任法》规定的两类侵权责任承担方式,在预防损害方面有着不同的制度设计,发挥着不同的威慑效能,也存在着一定的立法不足。为了充分发挥有效预防的作用,应对预防性侵权责任的归责事由、归责原则及构成要件,补偿性侵权责任的过错及比较过错情形、人身损害赔偿项目及赔偿标准进行完善。

控制与决策 , 2010,
Abstract: 针对准则权系数不完全确定,方案的准则值为区间直觉模糊数的随机多准则决策问题,提出一种基于记分函数的直觉随机多准则决策方法.首先定义离散型区间直觉随机变量、记分函数以及记分期望值和记分标准差;然后构造方案集记分期望值的最优线性规划模型得出最优权向量,进而求得方案集的联合直觉随机变量分布和综合记分标准期望区间值,再利用可能度方法确定方案排序;最后,算例分析结果表明了该方法的可行性和合理性.

Abstract:
目的:探讨初中生受欺负、抑郁、自尊三者之间的关系以及自尊在初中生受欺负和抑郁之间的中介效应。方法:采用儿童欺负问卷(中学版)、自尊量表(SES)和儿童抑郁调查量表(CDI),对银川市400名初一年级的学生进行问卷调查,将调查数据输入SPSS进行处理,研究受欺负、自尊和抑郁三者的关系。结果:受欺负与抑郁呈现显著正相关(p < 0.01);受欺负与自尊之间呈显著负相关(p < 0.01);抑郁与自尊呈显著负相关(p < 0.01)。自尊在受欺负与抑郁之间有部分中介效应。初中生受欺负程度对抑郁有预测作用。结论:自尊在受欺负和抑郁间有部分中介作用,受欺负通过自尊的部分中介效应对抑郁产生作用。
Objective: To explore the mediating effect of self-esteem on relationships between victimization and depression among junior middle school students. Methods: A total of 400 pupils of grade one from middle school were investigated by using Olweus’ Bully/Victim Questionnaire (middle school edition), Self-Esteem Scale (SES) and Children’s Depression Inventory (CDI). All the data were analyzed with SPSS. And we investigate the relationship among depression, self-esteem and victi-mization. Result: There was significantly positive correlation between victimization and depression (p < 0.01); victimization was significantly negatively correlated with self-esteem (p < 0.01); and the degree of self-esteem was significantly negatively correlated with that of depression (p < 0.01). The self-esteem partly mediated the path of victimization to depression. The victimization could predict depression and self-esteem. Conclusion: Self-esteem was a significant partly mediator between victimization and depression. Victimization could influence depression significantly through self-esteem as a partly mediator.

Abstract:
暴力行为是个人身心健康发展的影响因素之一,对家庭、社会和谐有很大程度的影响。本研究以在校中学生为研究对象,采用抽样调查的方法,旨在探讨网络暴力游戏和中学生暴力行为的相关,以便发现有暴力行为的人群具有的共性特点,利于提出有效且具有建设性的治疗方案。研究验证与发现:(1) 玩网络暴力游戏会改变人们对暴力行为的看法,且影响是长期的、潜移默化的;(2) 无论在网络世界还是在现实世界,中学生对网络游戏的模仿不具普遍现象;(3) 网络暴力游戏与中学生暴力行为有一定的相关,但“暴力”表现的方式并不相同;(4) 网络暴力游戏对中学生的暴力赞成程度及暴力情绪有明显的预测作用。
Violence is one of the factors affecting the personal health of body and mind development which has a great influence on the family and social harmony. Taking the middle school students of this study as the research object, study using the method of sampling survey, aims to explore the correlation of the violent behavior of the middle school students, in order to find the common characteristics of people with violence, to put forward effective and constructive treatment plan. The validation and found that: (1) Playing violent games will change the way people view of violence; the impact is long-term and subtle. (2) Both in the network world and in the real world, the middle school students imitations of online game is not a common phenomenon. (3) Network of violent games and middle students’ violent behavior related to a certain extent, but the “violence” is not the same performance. (4) Online violent game has a significant predictive effect on middle school students' violence in favor of violence and violence emotion.

Abstract: 室温下1.5mmol·l-1硫酸铵溶液体系中,以阳离子型表面活性剂十六烷基三甲基溴化胺为模板,四水硫酸锆为无机前驱体,按照配位体辅助模板机理合成介孔氧化锆前驱体。通过液相后移植工艺实现了钙对氧化锆的掺杂改性。借助xrd、tem、uv-vis、xps、n2吸-脱附及室温荧光光谱(rtpl)等方法对样品进行了表征分析。研究表明,钙离子进入氧化锆骨架结构中,掺杂改性后的氧化锆具有很强的荧光特性,其孔径尺寸在2.2nm左右。
美国公共债务可持续性的实证研究

Abstract: 运用经济增长率与公共债务利率比较、特定参考值判定、跨期预算约束检验和财政反应函数检验等四种方法,对美国公共债务可持续性进行的实证结果显示,1970—2011年,总体上,美国经济增长率低于公共债务利率水平;联邦财政赤字和联邦债务水平超过了“马约”规定的财政趋同指标;财政收入与财政支出之间不存在协整关系,财政盈余比例与公共债务比例之间尽管存在协整关系但其系数不符合理论预期和现实情况;财政盈余对公共债务的反应系数并非一直为正,且进入2000年以来大幅下降。因此,2008年金融危机爆发前美国公共债务已偏离可持续轨道,而金融危机恶化了美国联邦财政,其公共债务表现出不可持续的特征。美国政府可能通过创造低利率和温和通货膨胀来缓解和解决公共债务问题,对此,各国政府和央行应当给予充分关注,并考虑应对措施。

肝星状细胞的免疫学特性

复旦学报(医学版) , 2010,
Abstract: 活化的肝星状细胞(hepaticstellatecells,HSCs)可合成大量细胞外基质(extracellularmatrix,ECM),并可分泌转化生长因子β(transforminggrowthfactor-β,TGF-β)、血小板源性生长因子(plateletderivedgrowthfactor,PDGF)等促纤维化因子,在肝纤维化的发生发展中起着关键作用。近来研究发现活化的肝星状细胞具有多种免疫细胞的特性,可直接参与肝脏局部免疫调控,而免疫因素在肝纤维化发病机制中占据着重要地位,因此深刻认识肝星状细胞的免疫学特征有助于进一步阐明肝纤维化的发病机制。
