Development of Blood Oxygen Saturation Measure Instrument Based On ARM Technology

人体组织细胞进行新陈代谢所需要的氧是通过血液传输获取的。血红蛋白是组织中氧的主要载体，它由氧合血红蛋白(HbO2)和还原血红蛋白(Hb)组成。血氧饱和度(Sp02)是氧合血红蛋白在整个血红蛋白所占的百分比，是血液携氧能力的重要指标。近年来被广泛关注的测量技术是近红外光谱法，它是利用血液中血红蛋白等吸收谱在不同波长下差异来测定血氧饱和度。 随着微处理器运算能力的增加，ARM微处理器以其优越的性能必将成为家庭应用脉搏血氧饱和度测量仪采用的主要平台。本论文立足于家庭医疗监护，进行了基于WinCE5.0嵌入式操作系统的脉搏血氧饱和度测量仪研制，采用三星S3C2410核心芯片并且基于WinCE5.0的...Biological tissue cells obtain oxygen which is carried by blood to process metabolism. Hemoglobin (Hb), an intracellular protein, is the primary vehicle for transporting oxygen in the blood. It carries the oxygen and exchanges this for carbon dioxide oxygen released by the processes of metabolism from the cells. Hemoglobin forms an unstable, reversible bond with oxygen. It is oxy-hemoglobin in its...学位：工学硕士院系专业：信息科学与技术学院电子工程系_电路与系统学号：20043000

A Study on Employment Effects of Fiscal Expenditure Structure:Theoretical Analysis and Empirical Evidence

文章以Barro(1990)的内生经济增长模型为基础,将社会保障支出和科教文卫支出分别引入效用函数和生产函数中进行理论上分析,探究财政支出结构对就业的理论效应,同时利用中国1997-2014年的省级面板数据进行计量分析,以此验证理论模型所得到的推论。结果表明:从长期来看,科教文卫支出与社会保障支出对就业都具有显著的促进作用;从短期来看,科教文卫支出对就业的短期效应非常明显,而社会保障支出对就业的短期效应并不显著。另外,研究还发现技术进步对就业的影响不论在长期还是短期都不显著。Based on the endogenous economic growth model of Barro(1990),this paper incorporated social security expendi-ture and science,education,culture and public health expenditures into utility function and production function respectively,and then explored the theoretical effects of fiscal expenditure structure on employment. Moreover,this paper employed provin-cial-level panel data of China to make a quantitative analysis,so as to verify the inferences of theoretical model. The resultsshow that: In the long run,both two types of expenditures have a significant role in promoting employment. In the short term,science,education,culture and public health expenditures have a significant short term effect on employment,which is differ-ent from social security expenditure. In addition,the study also finds that the effect of technological progress on employment isnot significant whether in the long term or in the short term.国家社会科学基金重大项目(10ZD&036);; 教育部人文社会科学研究一般项目(14YJA790082

公共财政框架下财政监督内涵的新界定

在市场经济体制下,政府作为社会公众的受托人,为社会提供公共产品和服务以弥补市场失效,必须切实履行公共财政的受托责任,维护社会公众的利益。在这一过程中,财政监督的约束和纠偏作用显得尤其重要。随着我国市场经济体制的不断推进和公共财政框架的初步建立,财政监督问题受到极高的重视,十八大报告中提出“加强对财政全口径预算、决算的审查和监国家社会科学基金重大项目《健全公共财政体系研究》项目号的阶段性研究成

含镁离子电解质对氧化铝浆料流变性能的影响

通过高纯氧化铝陶瓷浆料粘度和zeta(ζ)电位等参数的考察,探讨了不同pH值下,含镁离子电解质对其流变性能的影响。结果表明,镁离子会降低氧化铝浆料的流变性能。在其存在下,无分散剂时与添加聚丙烯酸(PAA)作分散剂时,pH值分别为6.5和9.5的浆料具有良好的流变性能。无镁离子存在时,PAA的最佳添加量为0.5%;镁离子浓度为0.05mol/L时,该量增加至0.9%

A Research on the Threshold Effects of Fiscal Expenditure Competition on Economy——The Test Based on Provincial Panel Data in China

文章通过总结前人研究成果,提出财政支出竞争对经济影响的门限理论假说,并基于1997-2013年中国各省份的现实数据,利用门限面板模型进行实证检验。结果表明,财政支出竞争对经济的影响存在显著的门限效应,当地方经济发展处于较低水平时,财政支出竞争的负效应高于正效应,对经济增长显示出一定的抵制作用;当地方经济发展处于中、高水平时,财政支出竞争的正效应大于负效应,有利于经济增长。Based on summarizing the results of previous studies,this paper proposes a threshold theory hypothesis of the im-pact of fiscal expenditure competition on the economy, and applies the threshold panel model to make an empirical test onthe hypothesis by using the realistic data of Chinese provinces from 1997 to 2013.The results show that there are significantthreshold effects of fiscal expenditure competition on the economy.In the areas with low economic development level,the neg-ative effect of fiscal expenditure competition are higher than the positive effects, and show some inhibition on economicgrowth.In the areas with medium or high economic development level,the positive effect of fiscal expenditure competition isgreater than its negative effects,which is conducive to economic growth.国家社会科学基金重大项目(10ZD&036); 福建省软科学重点项目(2012R0079
