Abstract:
选取2008年3月~2011年12月25只封闭式股票型基金收益率和成交量、上证国债的收益率和成交量、3种人气指标(投资者信心指数,AR指标,心理线PSY指标)的周数据和月数据,建立基于周数据和月数据的计量回归模型,通过研究表明:1) 无论是在长期中还是在短期中市场的人气指标与基金相应期间的收益率成正相关性;2) 在短期中,基金的交易量与基金的收益率成正的相关性,但在长期中,基金的交易量已经不能对基金的收益率起解释作;3) 股票型基金的收益率与国债的收益率,成交量成负相关;4) 本期人气指标对本期的收益率起到正相关性,但对下一期的收益率解释力很弱。
Through the measurement regression model depending on weekly and monthly data of the returns and volume of 25 closed-end fund and the Shanghai bonds from March 2008 to December 2011 and three kinds of popular indicators (Investor Confidence Index, AR targets, indicators of psychological line PSY during the same period, we can find four important conclusions: 1) Whether long-term or the short-term, the market sentiment indicator and the Fund show a positive correlation; 2) In the short term, the fund’s transac-tion and the returns of the fund show a positive correlation, but in the long term, the fund’s transaction can’t explain the retunes of the Fund; 3) The returns of the fund and the returns of the bonds show a negative cor-relation; 4) Current sentiment indicator explain the returns of the funds for the same period, but the power of the explanation is weak for the next period.

钢桁公铁斜拉桥动力特性参数分析

武汉理工大学学报 , 2009,
Abstract: ?以某钢桁公铁斜拉桥为研究对象,建立空间有限元模型,从斜拉桥自振特性方面,分别就索塔高跨比、边中跨之比、主梁高跨比、辅助墩位置、主塔刚度、主桁斜竖杆刚度等一些特征参数展开了深入的比较研究。研究表明,对大跨度钢桁梁斜拉桥,最佳索塔高跨比为1/3;边中跨之比应不小于0.53;最佳的辅助墩布置范围在最外侧拉索索位与中索(与最长索和最短索距离相等的位置)索位之间;主梁高跨比对斜拉桥结构刚度影响不大;此外,桥塔刚度和主桁斜竖杆刚度是斜拉桥面内和面外稳定的主要力学参数。
考虑几何非线性的斜拉桥成桥索力计算

武汉理工大学学报 , 2008,
Abstract: ?基于非线性有限元法,采用分步迭代算法计算斜拉桥成桥索力。首先,考虑塔柱和主梁因柔度效应对弯曲能量吸收的权的分配,按最小能量法计算出索力的初值;然后,以结构线型变化最小为目标函数进行索力迭代计算,并确定出合理成桥索力。在迭代计算中考虑垂度效应等几何非线性的影响。比较了分别采用线性和几何非线性方法计算出的某大跨径斜拉桥的成桥索力,算例表明几何非线性对成桥索力的影响较小。

Abstract:

均温板(Vapor Chamber)为一两相流热传组件,具有将热量均匀扩散传递的功能,非常适合应用在不均匀发热的热源条件上。本文主要即是探讨均温板应用于非均匀发热的电子组件,如CPU、GPU及LED等,其扩散传递热量的能力。首先利用本文所开发的计算程序VCEK_ML V1及BaseResistance_ML,先行估算均温板的扩散传递热量的能力,再使用窗口软件VCTM V1.0配合热性能实验,分析整个均温板模块在非均匀热源物理条件的热流现象,最后可藉由热显像仪的温度分布结果验证均温板扩散热量的传递能力。结果显示,均温板模块可有效改善非均匀热物理条件的热分布现象,比纯铜及纯铝板佳。

应用DEA分析2006~2010年澳门银行业效率演进实例
Analysis of Evolution of Banking Efficiency of Macao during 2006-2010 with DEA Method
 [PDF]


Finance (FIN) , 2012, DOI: 10.12677/FIN.2012.23018
Abstract: 本研究,通过数据包络分析法(DEA)对澳门银行业从20062010年金融危机前后的成本效率(Cost-Efficiency)演进进行了实例评估。首先发现:按中介方法(Intermediation Approach)计算的成本效率5年总计增加23.3%,主要是因为澳门银行业总收入增加所致。澳门银行业内部业务结构也有所改变,有些银行大力增加存贷款规模,而另一些银行大力发展非利息收入占比,在考虑规模变化因素情况下(VRS)的技术效率(TE)增长1.5%。通过对成本效率分数与一些环境变量的线性回归分析,进一步得出:澳门地区银行业的产品输出范围(Scope)适度集中和增加支行平均资产额将会对今后澳门银行业整体成本效率具有正面影响;这就意味着,若现在的市场条件不作改变,澳门银行业内部的竞争可能会加剧。
In this study, the data envelope analysis (DEA) has been used to analyze the evolution of cost-efficiency of the banks of Macaoduring the period of 2006 to 2010. The cost-efficiency calculated with the intermediation approach has increased by 23.3%. This is because the total income of the Macao banks in- creased during this period and the internal structure of the banking business of Macao was changed. The technical efficiency has been calculated with consideration of variable return to scale and it was found that the technical efficiency increased by 1.5% if it was calculated with the intermediation approach. Linear re- gression of the cost-efficiency with
